Feature List

Randomized authenticated encryption with strong (256-bit) keys

HMAC256 algorithm for unforgeable integrity checking

Function to correctly hash a password and compare it.

By popular demand, added a function to hash a string using standard message digest (SHA256 is default)

Encrypt, Decrypt using RSA (OAEP padding). Generation of RSA keys.

Main Benefits

Your encrypted data cannot be tampered with without you knowing about it.

People can't tell when you're encrypting the same plaintext with the same key (Chosen Plaintext Attack secure scheme)
