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, shred files, 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 SHA3 hash 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>

Picocrypt for macOS is very simple as well. Download Picocrypt <a href="https://github.com/HACKERALERT/Picocrypt/releases/download/1.21/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.
## Linux
A Snap is available for Linux. Assuming you're on a Debian-based system, a simple `sudo 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.

# 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>Keep decrypted output even if it's corrupted or modified</strong>: Picocrypt automatically checks for integrity upon decryption. If the file has been modified or is corrupted, Picocrypt will automatically delete the output for the user's safety. If you want to keep the corrupted or modified data after decryption, check this option. Also, if this option is checked and the Reed-Solomon feature was used on the encrypted file, Picocrypt will attempt to recover as much of the file as possible during decryption.</li>
</ul>
In addition to these options for encryption and decryption, Picocrypt also provides a secure file shredder and a checksum generator.
In addition to these options for encryption and decryption, Picocrypt also provides a checksum generator for validating the integrity of sensitive files.
# 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 "offline" 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.
