Use SSH keys, Ed22519, X25519 and GCM to encrypt and decrypt messages and files for communication
version: 1.0.26 date: 2025-11-08 author: bestia.dev repository: GitHub

Hashtags: #maintained #ready-for-use #rustlang
My projects on GitHub are more like a tutorial than a finished product: bestia-dev tutorials.

⚠️ Security Warning

The implementation contained in this crate has never been independently audited!
USE AT YOUR OWN RISK!

Try it

For encrypted communication between two parties, both parties must use msg_enc_dec.
Install msg_enc_dec from GitHub.
It is preferred to use Rust locally to build the program, so you know exactly the source code and you can review it.
I use the CRUSTDE container to run Rust programs inside an isolated environment to not compromise my base operating system.

On Linux

Linux everywhere!
On Linux (I use Debian inside WSL on Windows):

cd ~/rustprojects
git clone git@github.com:bestia-dev/msg_enc_dec.git
code msg_enc_dec
cargo auto release
alias msg_enc_dec="./target/release/msg_enc_dec"
msg_enc_dec --help
