Struct nettle::cipher::insecure_do_not_use::ArcTwo

pub struct ArcTwo { /* fields omitted */ }

Ron Rivest's RC2 block cipher defined RFC 2268.

Note

RC2 is no longer considered a secure cipher. Only use it for legacy applications.

Implementations

impl ArcTwo

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

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

pub fn with_key_ekb(key: &[u8], ekb: u32) -> Self

Creates a new instance with key that can be used for both encryption and decryption. The ekb parameter can be used to limit the effective key size to ekb bits. A value of 0 is handled as 1024.

Trait Implementations

impl Cipher for ArcTwo

const BLOCK_SIZE: usize

Block size in bytes.

const KEY_SIZE: usize

Maximal key size in bytes.

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

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

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

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.
