Struct ring::aead::OpeningKey

pub struct OpeningKey { /* fields omitted */ }

A key for authenticating and decrypting (“opening”) AEAD-protected data.

C analog: EVP_AEAD_CTX with direction evp_aead_open

Go analog: [crypto.cipher.AEAD]

Methods

impl OpeningKey

pub fn new(     algorithm: &'static Algorithm,     key_bytes: &[u8] ) -> Result<OpeningKey, Unspecified>

Create a new opening key.

key_bytes must be exactly algorithm.key_len bytes long.

C analogs: EVP_AEAD_CTX_init_with_direction with direction evp_aead_open, EVP_AEAD_CTX_init.

Go analog: crypto.aes.NewCipher

• crypto.cipher.NewGCM

pub fn algorithm(&self) -> &'static Algorithm

The key's AEAD algorithm.
