Struct safe_crypto::SecretEncryptKey

pub struct SecretEncryptKey { /* fields omitted */ }

Reference counted secret encryption key used to decrypt data previously encrypted with PublicEncryptKey. Use gen_encrypt_keypair() to generate a public and secret key pair.

Methods

impl SecretEncryptKey

pub fn from_bytes(secret_key: [u8; 32]) -> Self

Construct secret key from given bytes. Useful when secret key was serialised before.

pub fn shared_secret(&self, their_pk: &PublicEncryptKey) -> SharedSecretKey

Computes a shared secret from our secret key and the recipient's public key.

pub fn into_bytes(self) -> [u8; 32]

Get the inner secret key representation.

pub fn anonymously_decrypt<T>(
    &self,
    ciphertext: &[u8],
    my_pk: &PublicEncryptKey
) -> Result<T, Error> where
    T: Serialize + DeserializeOwned, 

Decrypts serialised ciphertext encrypted using anonymous encryption.

With anonymous encryption we won't be able to verify the sender and tell who sent the ciphertext.

Returns deserialised type T in case of success. Can return Error in case of a deserialisation error, if the ciphertext is not valid, or if it can not be decrypted.

pub fn anonymously_decrypt_bytes(
    &self,
    ciphertext: &[u8],
    my_pk: &PublicEncryptKey
) -> Result<Vec<u8>, Error>

Decrypts bytestring ciphertext encrypted using anonymous encryption.

With anonymous encryption we won't be able to verify the sender and tell who sent the ciphertext.

Returns plaintext in case of success. Can return Error if the ciphertext is not valid or if it can not be decrypted.
