Struct nettle::cipher::insecure_do_not_use::Des

pub struct Des { /* fields omitted */ }

The Data Encryption Standard (DES) defined in FIPS 46-3.

Note

DES is no longer considered a secure cipher. Only use it for legacy applications.

Implementations

impl Des

pub fn with_key(key: &[u8]) -> Result<Self>

Creates a new instance with key that can be used for both encryption and decryption.

pub fn check_parity(key: &[u8]) -> bool

Checks the parity bits of the given DES key. Returns true if parity is correct, false otherwise.

pub fn fix_parity(key: &mut [u8])

Sets the parity bits in the given DES key.

Trait Implementations

impl Cipher for Des

const BLOCK_SIZE: usize

Block size in bytes.

const KEY_SIZE: usize

Maximal key size in bytes.

fn with_encrypt_key(key: &[u8]) -> Result<Des>

Creates a new cipher instance for encryption. The key parameter must have size KEY_SIZE.

fn with_decrypt_key(key: &[u8]) -> Result<Des>

Creates a new cipher instance for decryption. The key parameter must have size KEY_SIZE.

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

Encrypt src into dst. Both must have the same length. That length must be a multiple of BLOCK_SIZE. Blocks are processed in ECB mode.

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

Decrypt src into dst. Both must have the same length. That length must be a multiple of BLOCK_SIZE. Blocks are processed in ECB mode.

fn context(&mut self) -> *mut c_void

Returns a pointer to the C context struct of the cipher instance. Used internally by block modi.

fn raw_encrypt_function() -> RawCipherFunctionPointer

Pointer to the *_encrypt C function. Used internally for block modi.

fn raw_decrypt_function() -> RawCipherFunctionPointer

Pointer to the *_decrypt C function. Used internally for block modi.
