Struct safe_crypto::SharedSecretKey

pub struct SharedSecretKey { /* fields omitted */ }

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

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

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 PublicId and SecretId.

Returns ciphertext in case of success. Can return an EncryptionError in case of a serialisation error.

pub fn encrypt<T>(&self, plaintext: &T) -> Result<Vec<u8>, EncryptionError> where     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 PublicId and SecretId.

Returns ciphertext in case of success. Can return an EncryptionError in case of a serialisation error.

pub fn decrypt_bytes(&self, encoded: &[u8]) -> Result<Vec<u8>, EncryptionError>

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 EncryptionError 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, EncryptionError> where     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 EncryptionError in case of a deserialisation error, if the ciphertext is not valid, or if it can not be decrypted.
