Struct rc5_rs::Context

pub struct Context<W: Word = u32> {
    pub expanded_key: SecretVec<W>,
    pub rounds: usize,
}

RC5 Context

This struct holds the expanded key and the number of rounds that the algorithm will use. Use this struct if you are going to encrypt or decrypt multiple buffers of data with the same key.

Otherwise you can use the shorthand free standing functions encrypt and decrypt.

Fields

expanded_key: SecretVec<W>

rounds: usize

Implementations

impl<W: Word> Context<W>

pub fn new(key: Vec<u8>, rounds: usize) -> Result<Self, Error>

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

Encrypts bytes using the RC5 context and returns the ciphertext. The plaintext must be a multiple of the block size. Padding is not implemented.

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