Expand description

Synchronous block cipher trait.

Required Associated Types§

Source

type Key: AsRef<[u8]>

The byte array key type which specifies the size of the key used to instantiate the cipher.

Source

type Nonce: AsRef<[u8]>

The byte array nonce type which specifies the size of the nonce used in the cipher operations.

Required Methods§

Source

fn new_encrypt(key: &Self::Key, iv: &Self::Nonce) -> Self

Instantiate a new instance of a block cipher for encryption from a key and iv.

Source

fn new_decrypt(key: &Self::Key, iv: &Self::Nonce) -> Self

Instantiate a new instance of a block cipher for decryption from a key and iv.

Source

fn encrypt_padded(self, buffer: &[u8]) -> Result<Vec<u8>, CipherError>

Encrypts the given data in buffer, and returns the result (with padding) in a newly allocated vector, or a CipherError if the operation was unsuccessful.

Source

fn decrypt_padded(self, buffer: &[u8]) -> Result<Vec<u8>, CipherError>

Decrypts the given data in a buffer, and returns the result (with padding removed) in a newly allocated vector, or a CipherError if the operation was unsuccessful.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
