[−][src]Struct safe_crypto::SharedSecretKey
Precomputed shared secret key.
Can be created from a pair of our secret key and the recipient's public key. As a result, we'll get the same key as the recipient with their secret key and our public key.
Methods
impl SharedSecretKey
[src]
pub fn from_bytes(key: [u8; 32]) -> Self
[src]
Construct shared secret key from bytes. Useful when it was serialised before.
pub fn into_bytes(self) -> [u8; 32]
[src]
Convert the SharedSecretKey
into the raw underlying bytes.
For anyone who wants to store the shared secret key.
pub fn encrypt_bytes(&self, plaintext: &[u8]) -> Result<Vec<u8>, Error>
[src]
Encrypts bytestring plaintext
using authenticated encryption.
With authenticated encryption the recipient will be able to verify the authenticity
of the sender using a sender's public key.
If you want to use anonymous encryption, use the functions provided by PublicKeys
and SecretKeys
.
Returns ciphertext in case of success.
Can return an Error
in case of a serialisation error.
pub fn encrypt<T>(&self, plaintext: &T) -> Result<Vec<u8>, Error> where
T: Serialize,
[src]
T: Serialize,
Encrypts serialisable plaintext
using authenticated encryption.
With authenticated encryption the recipient will be able to verify the authenticity
of the sender using a sender's public key.
If you wish to encrypt bytestring plaintext, use encrypt_bytes
.
If you want to use anonymous encryption, use the functions provided by PublicKeys
and SecretKeys
.
Returns ciphertext in case of success.
Can return an Error
in case of a serialisation error.
pub fn decrypt_bytes(&self, encoded: &[u8]) -> Result<Vec<u8>, Error>
[src]
Decrypts bytestring encoded
encrypted using authenticated encryption.
With authenticated encryption we will be able to verify the authenticity of the sender using a sender's public key.
Returns plaintext 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 decrypt<T>(&self, ciphertext: &[u8]) -> Result<T, Error> where
T: Serialize + DeserializeOwned,
[src]
T: Serialize + DeserializeOwned,
Decrypts serialised ciphertext
encrypted using authenticated encryption.
With authenticated encryption we will be able to verify the authenticity of the sender using a sender's public key.
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.
