Struct Present

pub struct Present { /* private fields */ }

PRESENT block cipher.

Based on version 1.2 of the following Python implementation https://github.com/doegox/python-cryptoplus

Implementations

impl Present

pub fn try_new_rounds(key: Vec<u8>, rounds: usize) -> Result<Present>

pub fn try_new(key: Vec<u8>) -> Result<Present>

Create a new instance of the PRESENT cipher.

Valid key lengths are 80 and 128 bits. All other key lengths will return an error.

pub fn new_128(key: &[u8; 16]) -> Present

Create a new 128-bit PRESENT cipher instance.

pub fn new_80(key: &[u8; 10]) -> Present

Create a new 80-bit PRESENT cipher instance.

pub fn encrypt_block(&self, block: u64) -> u64

Encrypt a 64-bit block.

pub fn decrypt_block(&self, block: u64) -> u64

Decrypt a 64-bit block.
