Struct ChannelKey 

pub struct ChannelKey { /* private fields */ }

The AES-256-GCM key for channel targets.

Implementations

impl ChannelKey

pub fn derive(secret_key: &str) -> ChannelKey

HMAC-SHA256 of the fixed label, keyed by secret_key: 32 bytes.

pub fn encrypt(&self, plaintext: &[u8]) -> Vec<u8>

Nonce (12 random bytes) followed by the ciphertext and tag.

pub fn decrypt(&self, bytes: &[u8]) -> Result<Vec<u8>, CryptoError>

Reverses ChannelKey::encrypt; fails on a wrong key or any changed byte.
