⚠️ Word of Warning

Where possible, choose a cross-platform and well established encryption method, so that you are never faced with not being able to access your files using your current system.
Although well-established encryption methods are usually very secure, if the password is not strong, then an adversary may be able to gain access to your files, with a powerful enough GPU. If your system is compromised, then the password may also be able to be skimmed with a keylogger or other similar malware, so take care to follow good basic security practices

✳️ Notable Mentions

• AES Crypt - A light-weight and easy file encryption utility. It includes applications for Windows, Mac OS, BSD and Linux, all of which can be interacted with either through the GUI, CLI or programatically though an API (available for Java, C, C# and Python). Although it is well established, with an overall positive reputation, there have been some security issues raised recently.
• CryptSetup - is a convenient layer for use on top of dm-crypt. EncFS is a cross-platform file-based encryption module, for use within user local directories. geli is a disk encryption subsystem included with FreeBSD.
• BitLocker - is popular among Microsoft Windows and enterprise users, and provides fast, efficient and (if correctly configured) reasonably secure full drive encryption. However it is not open source, has poor compatibility with other operating systems, and has some very dodgy defaults, which could lead to your system being compromised. Similarly, Apple's FileVault on MacOS is easy and secure, but again, the source code is proprietary.
• DiskCryptor - Windows-only, open source, file and volume encryption solution, that makes a good alternative to BitLocker.

    📦 Open Source ˙

⚠️ Word of Warning

Many messaging apps claim to be secure, but if they are not open source, then this cannot be verified - and they should not be trusted. This applies to Telegram, Threema, Cypher, Wickr, Silent Phone and Viber, to name a few - these apps should not be used to communicate any sensitive data. Wire has also been removed, due to a recent acquisition

✳️ Notable Mentions

• Chat Secure
• KeyBase - Allows encrypted real-time chat, group chats, and public and private file sharing. It also has some nice features around cryptographically proving social identities, and makes PGP signing, encrypting and decrypting messages easy. However, since it was acquired by Zoom in 2020, it has no longer been receiving regular updates.
• OpenPGP - can be used over existing chat networks (such as email or message boards). It provides cryptographic privacy and authentication, PGP is used to encrypt messages.
  Note/ Issues with PGP PGP is not easy to use for beginners, and could lead to human error/ mistakes being made, which would be overall much worse than if an alternate, simpler system was used. Do not use 32-bit key IDs - they are too short to be secure. There have also been vulnerabilities found in the OpenPGP and S/MIME, defined in EFAIL, so although it still considered secure for general purpose use, for general chat, it may be better to use an encrypted messaging or email app instead.

Encrypted Email

Email is not secure - your messages can be easily intercepted and read. Corporations scan the content of your mail, to build up a profile of you, either to show you targeted ads or to sell onto third-parties. Through the Prism Program, the government also has full access to your emails (if not end-to-end encrypted) - this applies to Gmail, Outlook Mail, Yahoo Mail, GMX, ZoHo, iCloud, AOL and more.

For a more details comparison of email providers, see email-comparison.as93.net

• ProtonMail - An open-source, end-to-end encrypted anonymous email service. ProtonMail has a modern easy-to-use and customizable UI, as well as fast, secure native mobile apps.

• Tuta - Free and open source email service based in Germany. It has a basic intuitive UI, secure native mobile apps, anonymous signup, and a .onion site. Tuta has a full-featured free plan or a premium subscription for businesses allowing for custom domains ($12/ month). Tuta does not use OpenPGP like most encrypted mail providers, instead they use a standardized, hybrid method consisting of a symmetrical and an asymmetrical algorithm (with 128 bit AES, and 2048 bit RSA). This causes compatibility issues when communicating with contacts using PGP. But it does allow them to encrypt much more of the header data (body, attachments, subject lines, and sender names etc) which PGP mail providers cannot do. …

⚠️ Word of Warning

• When using an end-to-end encryption technology like OpenPGP, some metadata in the email header will not be encrypted.

• OpenPGP also does not support Forward secrecy, which means if either your or the recipient's private key is ever stolen, all previous messages encrypted with it will be exposed. You should take great care to keep your private keys safe.

Email Clients

Email clients are the programs used to interact with the mail server. For hosted email, then the web and mobile clients provided by your email service are usually adequate, and may be the most secure option. For self-hosted email, you will need to install and configure mail clients for web, desktop or mobile. A benefit of using an IMAP client, is that you will always have an offline backup of all email messages (which can then be encrypted and archived), and many applications let you aggregate multiple mailboxes for convenience. Desktop mail clients are not vulnerable to the common browser attacks, that their web app counterparts are.

• Mozilla Thunderbird - Free and open source email application developed and backed by Mozilla -it's secure, private easy and customizable.

Mail Forwarding

Revealing your real email address online can put you at risk. Email aliasing allows messages to be sent to [anything]@my-domain.com and still land in your primary inbox.

Now more than ever we are relying on software to help with team collaboration. Unfortunately many popular options, such as Slack, Microsoft Teams, Google for Work and Discord all come with some serious privacy implications.
Typical features of team collaboration software includes: instant messaging, closed and open group messaging, voice and video conference calling, file sharing/ file drop, and some level or scheduling functionality.

• Rocket.Chat - Easy-to-deploy, self-hosted team collaboration platform with stable, feature-rich cross-platform client apps. The UI is fast, good looking and intuitive, so very little technical experience is needed for users of the platform. Rocket.Chat's feature set is similar to Slack's, making it a good replacement for any team looking to have greater control over their data. …

• RetroShare - Secure group communications, with the option to be used over Tor or I2P. Fast intuitive group and 1-to-1 chats with text and rich media using decentralized chat rooms, with a mail feature for delivering messages to offline contacts. A channels feature makes it possible for members of different teams to stay up-to-date with each other, and to share files. Also includes built-in forums, link aggregations, file sharing and voice and video calling. RetroShare is a bit more complex to use than some alternatives, and the UI is quite retro, so may not be appropriate for a non-technical team. …

However it's important to keep security in mind while configuring your IRC instance and ensure that channels are properly encrypted - IRC tends to be better for open communications. There's a variety of clients to choose from - popular options include: The Longe (Web-based), HexChat (Linux), Pidgin (Linux), WeeChat (Linux, terminal-based), IceChat (Windows), XChat Aqua (MacOS), Palaver (iOS) and Revolution (Android). …

⚠️ Word of Warning

• Having many extensions installed raises entropy, causing your fingerprint to be more unique, hence making tracking easier.

• Much of the functionality of the above addons can be applied without installing anything, by configuring browser settings yourself. For Firefox this is done in the user.js
• Be careful when installing unfamiliar browser add-ons, since some can compromise your security and privacy. At the time of writing, the above list were all open source, verified and 'safe' extensions.
• In most situations, only a few of the above extensions will be needed in combination.
• See the arkenfox wiki for more information on the obsolescence and purposelessness of many popular extensions, and why you may only need a very limited set.

• A VPN does not make you anonymous - it merely changes your public IP address to that of your VPN provider, instead of your ISP. Your browsing session can still be linked back to your real identity either through your system details (such as user agent, screen resolution even typing patterns), cookies / session storage, or by the identifiable data that you enter. Read more about fingerprinting

• Logging - If you choose to use a VPN because you do not agree with your ISP logging your full browsing history, then it is important to keep in mind that your VPN provider can see (and mess with) all your traffic. Many VPNs claim not to keep logs, but you cannot be certain of this (VPN leaks). See this article for more
• IP Leaks - If configured incorrectly, your IP may be exposed through a DNS leak. This usually happens when your system is unknowingly accessing default DNS servers rather than the anonymous DNS servers assigned by an anonymity network or VPN. Read more: What is a DNS leak, DNS Leak Test, How to Fix a DNS Leak
• Stealth - It will be visible to your adversary that you are using a VPN (usually from the IP address), but other system and browser data, can still reveal information about you and your device (such as your local time-zone, indicating which region you are operating from)
• Many reviews are sponsored, and hence biased. Do your own research, or go with one of the above options
• Using Tor (or another Mix Network) may be a better option for anonimity

✳️ Notable Mentions

If you don't trust a VPN provider not to keep logs, then you could self-host your own VPN. This gives you you total control, but at the cost of anonymity (since your cloud provider, will require your billing info). See Streisand, to learn more, and get started with running a VPN. Digital Ocean provides flexible, secure and easy Linux VMs, (from $0.007/hour or $5/month), Here is a 1-click install scriptfor on Digital Ocean, by Carl Friess. Recently distributed self-hosted solutions for running your own VPNs have become more popular, with services like Outline letting you spin up your own instance and share it with friends and family. Since it's distributed, it is very resistant to blocking, and gives you world-wide access to the free and open internet. And since you have full control over the server, you can be confident that there is no logging or monitoring happening. However it comes at the cost of anonymity, especially if it's only you using your instance.

ℹ️ Further Info

While choosing a VPN, consider the following: Logging policy (logs are bad), Jurisdiction (avoid 5-eyes), Number of servers, availability and average load. Payment method (anonymous methods such as BTC, Monero or cash are better), Leak protection (1st-party DNS servers = good, and check if IPv6 is supported), protocols (OpenVPN and WireGuard = good). Finally, usability of their apps, user reviews and download speeds.

I2P is less mature, but fully-distributed and self-organising, its smaller size means that it hasn't yet been blocked or DOSed much. …
• Freenet - Freenet is easy to setup, provides excellent friend To Friend Sharing vs I2P, and is great for publishing content anonymously. It's quite large in size, and very slow so not the best choice for casual browsing. …
  • Stats

    ˙

⚠️ Word of Warning

To provide low-latency browsing, Tor does not mix packets or generate cover traffic. If an adversary is powerful enough, theoretically they could either observe the entire network, or just the victims entry and exit nodes. It's worth mentioning, that even though your ISP can not see what you are doing, they will be able determine that you are using a mix net, to hide this - a VPN could be used as well. If you are doing anything which could put you at risk, then good OpSec is essential, as the authorities have traced criminals through the Tor network before, and made arrests. Don't let Tor provide you a false sense of security - be aware of information leaks through DNS, other programs or human error. Tor-supported browsers may might lag behind their upstream forks, and include exploitable unpatched issues. See #19

Note: The Tor network is run by the community. If you benefit from using it and would like to help sustain uncensored internet access for all, consider running a Tor relay

DNS Protocols

DNS-over-TLS was proposed in RTC-7858 by the IETF, then 2 years later, the DNS-over-HTTPS specification was outlined in RFC8484 in October '18. DNSCrypt, is a protocol that authenticates communications between a DNS client and a DNS resolver. It prevents DNS spoofing, through using cryptographic signatures to verify that responses originate from the chosen DNS resolver, and haven't been tampered with. DNSCrypt is a well battle-tested protocol, that has been in use since 2013, and is still widely used.

Metadata Removal

Exif/ Metadata is "data about data", this additional information attached to files can lead us to share significantly more information than we intended to.

For example, if you upload an image of a sunset to the internet, but don't remove the metadata, it may reveal the location (GPS lat + long) of where it was taken, the device is was taken on, precise camera data, details about modifications and the picture source + author. Social networks that remove metadata from your photos, often collect and store it, for their own use. This could obviously pose a security risk, and that is why it is recommended to strip out this data from a file before sharing.

It's possible (but slower) to do this without a third-party tool. For Windows, right click on a file, and go to: Properties --> Details --> Remove Properties --> Remove from this File --> Select All --> OK.

Alternatively, with ImageMagic installed, just run convert -strip path/to/image.png to remove all metadata.

If you have GIMP installed, then just go to File --> Export As --> Export --> Advanced Options --> Uncheck the "Save EXIF data" option.

Often you need to perform meta data removal programmatically, as part of a script or automation process.

✳️ Notable Mentions

There's no need to use a third-party tool. You can boot into a UNIX-based system, mount the disk you need to erase, and use a command to write it with arbitrary data. For best results, this process should be repeated several times. This is a good way to wipe a disk, before selling or destroying it, to protect your data.

Such as the dd command, is a tool to convert and copy files, but running sudo dd if=/dev/zero of=/dev/sdX bs=1M will quickly overwrite the whole disk with zeros. Or badblocks which is intended to search for all bad blocks, but can also be used to write zeros to a disk, by running sudo badblocks -wsv /dev/sdd.

An effective method of erasing an SSD, it to use hdparm to issue a secure erase command, to your target storage device, for this, see step-by-step instructions via: wiki.kernel.org.

Finally, srm can be use to securely remove files or directories, just run srm -zsv /path/to/file for a single pass over.

⚠️ Word of Warning

It is not recommended to root, or flash your device with a custom ROM if you are not an advanced user. There are risks involved

• Although the above ROMs omit Google, they do open up other security issues: Without DM-verity on the system partition, the file system could be tampered with, and no verified boot stack, the kernel/initramfs also could be edited. You should understand the risks, before proceeding to flash a custom ROM to your device
• You will need to rely on updates from the community, which could be slower to be released - this may be an issue for a time-urgent, security-critical patch
• It is also possible to brick your device, through interrupted install or bad software
• Finally, rooting and flashing your device, will void your warranty

Desktop Operating Systems

Windows and MacOS have many features that violate your privacy. Microsoft and Apple are able to collect all your data (including, but not limited to: keystrokes, searches and mic input, calendar data, music, photos, credit card information and purchases, identity, passwords, contacts, conversations and location data). Microsoft Windows is also more susceptible to malware and viruses, than alternative systems.

Switching to Linux is a great choice in terms of security and privacy - you don't need necessarily need to use a security distro, any well-maintained stable distro is going to be considerably better than a proprietary OS

• Qubes OS - Open-source security-oriented operating system for single-user desktop computing. It uses virtualisation, to run each application in its own compartment to avoid data being leaked.

Other security-focused distros include: TENS OS, Fedora CoreOS, Kodachi and IprediaOS (Avoid systems that are not being actively maintained)

ℹ️ Further Info

General Purpose Linux Distros

If you do not want to use a specalist security-based distro, or you are new to Unix - then just switching to any well-maintained Linux distro, is going to be significantly more secure and private than Windows or Mac OS. Since it is open source, major distros are constantly being audited by members of the community. Linux does not give users admin rights by default - this makes is much less likely that your system could become infected with malware. And of course, there is no proprietary Microsoft or Apple software constantly monitoring everything you do.

Some good distros to consider would be: Fedora, Debian, or Arch- all of which have a large community behind them. Manjaro (based of Arch) is a good option, with a simple install process, used by new comers, and expers alike. POP_OS and PureOS are reasonably new general purpose Linux, with a strong focus on privacy, but also very user-friendly with an intuitive interfac and install process. See Detailed Comparison.

BSD

BSD systems arguably have far superior network stacks. OpenBSD is designed for maximum security — not just with its features, but with its implementation practices. It's a commonly used OS by banks and critical systems. FreeBSD is more popular, and aims for high performance and ease of use.

Windows

Two alternative options for Windows users are Windows 10 AME (ameliorated) project and the LTSC stream.

• Windows 10 AME AME project aims at delivering a stable, non-intrusive yet fully functional build of Windows 10 to anyone, who requires the Windows operating system natively. Core applications, such as the included Edge web-browser, Windows Media Player, Cortana, as well as any appx applications (appx apps will no longer work), have also been successfully eliminated. The total size of removed files is about 2 GB. Comes as a pre-built ISO or option to build from scratch with de-bloat scripts. Strong, supportive community on Telegram.
• Windows 10 LTSC LTSC provides several security benefits over a standard Win 10 Installation. LTSC or Long Term Servicing Channel is a lightweight, low-cost Windows 10 version, that is intended for specialized systems, and receives less regular feature updates. What makes it appealing, is that it doesn't come with any bloatware or non-essential applications, and needs to be configured from the ground up by the user. This gives you much better control over what is running on your system, ultimately improving security and privacy. It also includes several enterprise-grade security features, which are not available in a standard Windows 10 instance. It does require some technical knowledge to get started with, but once setup should perform just as any other Windows 10 system. Note that you should only download the LTSC ISO from the Microsoft's official page

Improve the Security and Privacy of your current OS

After installing your new operating system, or if you have chosen to stick with your current OS, there are a couple of things you can do to improve security. See: Windows 10 security guide, Mac OS security guide or Linux security guide.

⚠️ Word of Warning

(The above software was last tested on 01/05/20). Many of the above tools are not necessary or suitable for beginners, and can cause your system to break - only use software that you need, according to your threat model. Take care to only download from an official/ legitimate source, verify the executable before proceeding, and check reviews/ forums. Create a system restore point, before making any significant changes to your OS (such as disabling core features).

From a security and privacy perspective, Linux may be a better option.

⚠️ Word of Warning

For Microsoft Windows, Windows Defender provides totally adequate virus protection in most cases. These tools are intended for single-use in detecting/ removing threats on an infected machine, and are not recommended to be left running in the background, use portable editions where available.

Many anti virus products have a history of introducing vulnerabilities themselves, and several of them seriously degrade the performance of your computer, as well as decrease your privacy. Never use a free anti-virus, and never trust the companies that offer free solutions, even if you pay for the premium package. This includes (but not limited to) Avast, AVG, McAfee and Kasperky. For AV to be effective, it needs intermate access to all areas of your PC, so it is important to go with a trusted vendor, and monitor its activity closely.

⚠️ Word of Warning

Not all cryptocurrencies are anonymous, and without using a privacy-focused coin, a record of your transaction will live on a publicly available distributed ledger, forever. If you send of receive multiple payments, ensure you switch up addresses or use a mixer, to make it harder for anyone trying to trace your transactions. Cryptocurrencies that allow private and public transactions may reveal meta data about your transactions and balances when funds are moving from private to public addresses which can compromise your privacy with methods similar to a knapsack problem.

Always store private keys somewhere safe, but offline

Note: Cryptocurrency prices can go down. Storing any wealth in crypto may result in losses. If you are new to digital currencies - do your research first, don't invest more than you can afford to loose, and be very weary crypto-related scams are very common. as is and cryptocurrency-related malware.

This is NOT financial advice

✳️ Notable Mentions

Other privacy-focused cryptocurrencies include: PIVX, Verge, and Piratechain.

ℹ️ Further Info

It is still possible to use currencies that have a public ledger 'privately', but you will need to take great care not to cause any transactions to be linked with your identity or activity. For example, avoid exchanges that require KYC, and consider using a service such as Local Bitcoins. If you use a Bitcoin ATM, then take care to not be physically tracked (CCTV, phone location, card payments etc)

Atomic has a great feature set, and supports swapping, staking, and lending directly from the app. However, most of Atomic's features require an active internet connection, and Atomic does not support hardware wallets yet.

⚠️ Word of Warning

Avoid using any online/ hot-wallet, as you will have no control over the security of your private keys.

Offline paper wallets are very secure, but ensure you store it properly - to keep it safe from theft, loss or damage.

✳️ Notable Mentions

Metamask (Ethereum and ERC20 tokens) is a bridge that allows you to visit and interact with distributed web apps in your browser. Metamask has good hardware wallet support, so you can use it to swap, stake, sign, lend and interact with dapps without you're private key ever leaving your device. However the very nature of being a browser-based app means that you need to stay vigilant with what services you give access to.

Virtual Credit Cards

Virtual cards generated provide an extra layer of security, improve privacy and help protect from fraud. Most providers have additional features, such as single-use cards (that cannot be charged more than once), card limits (so you can be sure you won't be charged more than you expected) and other security controls.

In most countries KYC is required. The bank will of course be able to see all your transactions. Be sure to read their privacy policy and terms of service beforehand. Not all services are available in all countries.

• Privacy.com - Privacy.com has a good reputation, and is the largest virtual card provider in the US. Unlike other providers, it is free for personal use (up to 12 cards per month) with no fees, apps and support is good. There is a premium plan for $10/month, with 1% cashback and 36 cards/month. …

Other Payment Methods

• Cash - Actual physical cash is still the most private option, with no chance of leaving any transactional records. …
• Gift Cards - Gift cards can be purchased for cash in many convenience stores, and redeemed online for goods or services. Try to avoid CCTV as best as possible. …
• Pre-paid Cards - Similarly to gift cards, buying a pre-paid card for cash can enable you to purchase goods and services in stores that only accept card payments. …

⚠️ Word of Warning

Note that credit card providers heavily track transaction metadata, which build up a detailed picture of each persons spending habits. This is done both to provide improved fraud alerts, but also because the data is extremely valuable and is often 'anonymized' and sold to 3rd parties. Hence your privacy is degraded if these cards are used for daily transactions

ℹ️ Further Info

Paying for goods and services is a good example of where privacy and security conflict; the most secure option would be to pay with credit card, since most providers include comprehensive fraud protection, whereas the most private option would be to pay using crypto currency or cash, since neither can be easily tied back to your identity.

Final Notes

Conclusion

Many corporations put profit before people, collecting data and exploiting privacy. They claim to be secure but without being open source it can't be verified, until there's been a breach and it's too late. Switching to privacy-respecting open source software will drastically help improving your security, privacy and anonymity online.

However, that's not all you need to do. It is also important to: use strong and unique passwords, 2-factor authentication, adopt good networking practices and be mindful of data that are collected when browsing the web. You can see the full personal security checklist for more tips to stay safe.

Important Considerations

Compartmentalise, Update and Be Ready
No piece of software is truly secure or private. Further to this, software can only as secure as the system it is running on. Vulnerabilities are being discovered and patched all the time, so you much keep your system up-to-date. Breaches occur regularly, so compartmentalise your data to minimise damage. It's not just about choosing secure software, you must also follow good security practices.

Attack Surface
It is a good idea to keep your trusted software base small, to reduce potential attack surface. At the same time trusting a single application for too many tasks or too much personal data could be a weakness in your system. So you will need to judge the situation according to your threat model, and carefully plan which software and applications you trust with each segment of your data.

Convenience Vs Security
There is often a trade-off between convenience and security. Construct a threat model, and choose a balance that is right for you. In a similar way in some situations there is privacy and security conflict (e.g. Find My Phone is great for security, but terrible for privacy, and anonymous payments may be good for privacy but less secure than insured fiat currency). Again it is about assessing your situation, understanding the risks and making an informed decision.

Hosted Vs Self-Hosted Considerations
When using a hosted or managed application that is open-source software - there is often no easy way to tell if the version running is the same as that of the published source code (even published signatures can be faked). There is always the possibility that additional backdoors may have been knowingly or unknowingly implemented in the running instance. One way round this is to self-host software yourself. When self-hosting you will then know for sure which code is running, however you will also be responsible for the managing security of the server, and so may not be recommended for beginners.

Open Source Software Considerations
Open source software has long had a reputation of being more secure than its closed source counterparts. Since bugs are raised transparently, fixed quickly, the code can be checked by experts in the community and there is usually little or no data collection or analytics. That being said, there is no piece of software that it totally bug free, and hence never truly secure or private. Being open source, is in no way a guarantee that something is safe. There is no shortage of poorly-written, obsolete or sometimes harmful open source projects on the internet. Some open source apps, or a dependency bundled within it are just plain malicious (such as, that time Colourama was found in the PyPI Repository)

Proprietary Software Considerations
When using a hosted or proprietary solution - always check the privacy policy, research the reputation of the organisation, and be weary about which data you trust them with. It may be best to choose open source software for security-critical situations, where possible.

Maintenance
When selecting a new application, ensure it is still being regularly maintained, as this will allow for recently discovered security issues to be addressed. Software in an alpha or beta phase, may be buggy and lacking in features, but more importantly - it could have critical vulnerabilities open to exploit. Similarly, applications that are no longer being actively maintained may pose a security risk, due to lack of patching. When using a forked application, or software that is based on an upstream code base, be aware that it may receive security-critical patches and updates at a slightly later date than the original application.

This List: Disclaimer
This list contains packages that range from entry-level to advanced, a lot of the software here will not be appropriate for all audiences. It is in no way a definitive list of secure applications, and aims only to be a guide, a collection of software and services that myself and other contributors have used, and would recommend. There will always be new vulnerabilities discovered or introduced, bugs and security-critical glitches, malicious actors and poorly configured systems. It is up to you to do your research, draw up a threat model, and decide where and how your data are managed.

If you find something on this list that should no longer be deemed secure or private/ or should have a warning note attached, please raise an issue. In the same way if you know of something that is missing, or would like to make an edit, then pull requests are welcome, and are much appreciated!
