Trait bdrck::crypto::key::AbstractKey

pub trait AbstractKey {
    fn get_digest(&self) -> Digest;
    fn encrypt(
        &self, 
        plaintext: &[u8], 
        nonce: Option<Nonce>
    ) -> Result<(Option<Nonce>, Vec<u8>), Error>;

        ciphertext: &[u8]
    ) -> Result<Vec<u8>, Error>;
}

An AbstractKey is any cryptographic structure which supports encryption and decryption.

Required methods

fn get_digest(&self) -> Digest

Return a digest/signature computed from this key.

fn encrypt(
    &self,
    plaintext: &[u8],
    nonce: Option<Nonce>
) -> Result<(Option<Nonce>, Vec<u8>), Error>

Encrypt the given plaintext with this key. This function optionally takes a nonce as an argument. If this key's encryption algorithm utilizes a nonce, the provided one will be used.

This function returns the ciphertext, as well as a Nonce (if one was used for encryption). If a Nonce was provided, that same Nonce is returned.

fn decrypt(
    &self,
    nonce: Option<&Nonce>,
    ciphertext: &[u8]
) -> Result<Vec<u8>, Error>

Decrypt the given ciphertext using this key and the nonce which was generated at encryption time (if any), returning the plaintext.
