Picocrypt is a very small (hence <i>Pico</i>), very simple, yet very secure encryption tool that you can use to protect your files, generate checksums, and much more. It's designed to be the <i>go-to</i> tool for encryption, with a focus on security, simplicity, and reliability. Picocrypt uses the secure XChaCha20 cipher and the Argon2 key derivation function to provide a high level of security, even from three-letter agencies like the NSA. It's designed for maximal security, making absolutely no compromises security-wise, and is built with Go's standard x/crypto modules. <strong>Your privacy and security is under attack. Take it back with confidence by protecting your files with Picocrypt.</strong>

Please donate to Picocrypt on <a href="https://opencollective.com/picocrypt">Open Collective</a> (crypto is accepted) to raise money for a potential audit from Cure53. Because this is a project that I spend many hours on and make no money from, I cannot pay for an audit myself. <i>Picocrypt needs support from its community.</i>
# Downloads
<strong>Important:</strong> There's an outdated and useless piece of abandonware called PicoCrypt on the Internet, which was last updated in 2005. PicoCrypt is not related in any way to Picocrypt (this project). Make sure you only download Picocrypt from this repository to ensure that you get the authentic and backdoor-free Picocrypt.
## Windows
Picocrypt for Windows is as simple as it gets. To download the latest, standalone, and portable executable for Windows, click <a href="https://github.com/HACKERALERT/Picocrypt/releases/download/1.22/Picocrypt.exe">here</a>. If Windows Defender or your antivirus flags Picocrypt as a virus, please do your part and submit it as a false positive for the betterment of everyone.

## macOS
Picocrypt for macOS is very simple as well. Download Picocrypt <a href="https://github.com/HACKERALERT/Picocrypt/releases/download/1.22/Picocrypt.app.zip">here</a>, extract the zip file, and run Picocrypt which is inside. If you can't open Picocrypt because it's not from a verified developer, right click on Picocrypt and hit "Open". If you still get the warning, right click on Picocrypt and hit "Open" again and you should be able to start Picocrypt.

A Snap is available for Linux. Assuming you're on a Debian-based system, a simple `apt install snapd` and `snap install picocrypt` will be enough. For other distros such as Fedora, detailed instructions are available at https://snapcraft.io/picocrypt. Due to the complexity of dependencies and static linking, I don't distribute standalone .deb or .rpm binaries because they would be unreliable and not worth the hassle. Snapcraft manages all dependencies and runtimes automatically and is the recommended way to run Picocrypt on any major Linux distribution. Additionally, Snapcraft provides better security and containerization than Flatpaks and AppImages, which is important for an encryption tool like Picocrypt. If you would prefer not to deal with Canonical, remember that building from source is always an option.
## Paranoid Packs
The Paranoid Pack is a compressed archive that contains executables for every version of Picocrypt ever released for Windows, macOS, and Linux. As long as you have it stored in a place you can access, you'll be able to open it and use any version of Picocrypt in case this repository mysteriously vanishes or the entire Internet burns down. Think of it as a seed vault for Picocrypt. As long as one person has the Paranoid Pack within reach, they can share it with the rest of the world and keep Picocrypt functional in cases of catastrophic events like GitHub shutting down suddenly or the NSA capturing me (just in case, you know?). The best way to ensure Picocrypt is accessible many decades from now is to keep a Paranoid Pack in a safe place. So if you are worried about being unable to access Picocrypt in the future, well, here's your solution.

# Why Picocrypt?
Why should you use Picocrypt instead of BitLocker, NordLocker, VeraCrypt, AxCrypt, or 7-Zip? Here are a few reasons why you should choose Picocrypt:

<li><strong>Split files into chunks</strong>: Don't feel like dealing with gargantuan files? No worries! With Picocrypt, you can choose to split your output file into custom-sized chunks, so large files can become more manageable and easier to upload to cloud providers. Simply choose a unit (KiB, MiB, or GiB) and enter your desired number for that unit. To decrypt the chunks, simply drag one of them into Picocrypt, and the chunks will be automatically recombined during decryption.</li>
</ul>
In addition to these comprehensive options for encryption and decryption, Picocrypt also provides a checksum generator for validating the integrity of sensitive files, which supports numerous hash functions like MD5, BLAKE2, and SHA3.
# Security
For more information on how Picocrypt handles cryptography, see <a href="Internals.md">Internals</a> for the technical details. If you're worried about the safety of me or this project, let me assure you that this repository won't be hijacked or backdoored. I have 2FA (TOTP) enabled on all accounts with a tie to Picocrypt (GitHub, Google, Reddit, Ubuntu One/Snapcraft, Discord, etc.), in addition to full-disk encryption on all of my portable devices. For further hardening, Picocrypt uses my isolated forks of dependencies and I fetch upstream only when I have taken a look at the changes and believe that there aren't any security issues. This means that if a dependency gets hacked or deleted by the author, Picocrypt will be using my fork of it and remain completely unaffected. You can feel confident about using Picocrypt.
Note: Current versions of Picocrypt will make a network request to raw.githubusercontent.com to check whether a newer verison of Picocrypt is available. In the future, when Picocrypt becomes production-ready, I will remove the update checker and Picocrypt will become completely isolated from the Internet.
