Struct nettle::cipher::insecure_do_not_use::ArcTwo

pub struct ArcTwo { /* private fields */ }

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 = 8usize

Block size in bytes.

const KEY_SIZE: usize = 128usize
