Struct Des 

pub struct Des { /* private fields */ }

A DES cipher keyed with a single 64-bit key (including parity bits).

Implementations

impl Des

pub fn new(key: &[u8; 8]) -> Result<Self, DesKeyError>

Create a new DES instance from an 8-byte key.

pub fn new_unchecked(key: &[u8; 8]) -> Self

Create DES from an 8-byte key without weak-key screening.

This is intended for known-answer tests that intentionally exercise weak key behavior from FIPS 74 style vector sets.

pub fn new_wiping(key: &mut [u8; 8]) -> Result<Self, DesKeyError>

Create a new DES instance and wipe the provided key buffer.

pub fn encrypt_block(&self, block: &[u8; 8]) -> [u8; 8]

Encrypt a single 64-bit block (ECB mode).

pub fn decrypt_block(&self, block: &[u8; 8]) -> [u8; 8]

Decrypt a single 64-bit block (ECB mode).

Trait Implementations

impl BlockCipher for Des

const BLOCK_LEN: usize = 8

Block length in bytes.

fn encrypt(&self, block: &mut [u8])

Encrypt one block in-place. Panics if block.len() != BLOCK_LEN.

fn decrypt(&self, block: &mut [u8])

Decrypt one block in-place. Panics if block.len() != BLOCK_LEN.

impl Drop for Des

fn drop(&mut self)

Executes the destructor for this type.
