Fencryption (binary)

I first built this program with typescript (see fencryption-typescript) but I switched to Rust because typescript was not the most suitable language for this kind of project and also because I wanted to try Rust and low-level programming.

Fencryption is program to encrypt and decrypt files and full directories. Note that this project is at an early stage of development.

THERE IS ABSOLUTELY NO WARRANTY THAT THIS PROGRAM DOES NOT CONTAIN VULNERABILITIES. USE IT AT YOUR OWN RISK.

This program is not supposed to be used in "real conditions" as it is a mere personal project. Although I think above v1.0 (not released yet) the commands encrypt and decrypt should be pretty safe.

Limitations/Issues

• When encrypting files, make sure to encrypt and decrypt them with the same version of fencryption (it is very likely that different versions will not work the same way)

Roadmap

• Provide better help about commands
• Add default file encryption features
• Add stream enc-/decryption features
• Setup directory recursive mapping
• Improve log, error handling and cli
• Implement multithreading
• Edit encryption process so the output file is smaller
• Add commands to enc/decrypt text/base64
• Come up with a stable version (v1.0)

fencryption-lib

The lib used in the fencryption binary. You can take a look, it has some interesting things...
