A trivial file encryption/decryption application written in C++. It uses XChaCha20-Poly1305 for symmetric encryption and Argon2i for key derivation. Asymmetric encryption may be added later.
Only depends on libsodium.
cmake .
make -j2
% encrypt-cli secret-notes.txt
Please enter your symmetric encryption key: mypassword
Please confirm your symmetric encryption key: mypassword
Deriving key, please wait...
