Vaulty

Encrypt/Decrypt with ChaCha20-Poly1305

Vaulty is an extremely lightweight encryption/decryption tool which uses ChaCha20-Poly1305 to provide 256-bit authenticated symmetric encryption (AEAD) using Scrypt as the password based key derivation function.

Usage - Symmetric Encryption

Symmetric encryption is where encryption and decryption happens with the same password/key. If Alice is sharing an encrypted file with Bob then both Alice and Bob need to know the same password/key. With symmetric encryption both parties need a secure mechanism to exchange the password/key without anyone else (i.e. Eve) obtaining it.

echo "Hello World" | vaulty encrypt
$VAULTY;AY3eJ98NF6WFDMAP62lRdl58A2db5XJ2gNvKd0nmDs5ZrmNlJ8TSURpxc3bNF1iGw77dHA==

echo "$VAULTY;..." | vaulty decrypt
Hello World

Usage - SHA256

echo "Hello World" | vaulty sha256
