Expand description

A trait for the ability to encrypt and decrypt tickets.

Required Methods§

Source

fn encrypt(&self, plain: &[u8]) -> Option<Vec<u8>>

Encrypt and authenticate plain, returning the resulting ticket. Return None if plain cannot be encrypted for some reason: an empty ticket will be sent and the connection will continue.

Source

fn decrypt(&self, cipher: &[u8]) -> Option<Vec<u8>>

Decrypt cipher, validating its authenticity protection and recovering the plaintext. cipher is fully attacker controlled, so this decryption must be side-channel free, panic-proof, and otherwise bullet-proof. If the decryption fails, return None.
