    C: Cipher,
    IV: InitialVec<C>, 

pub fn new(c: C, iv: IV) -> Result<Self, CryptoError>

pub fn update_iv(&mut self) -> Result<&Vec<u8>, CryptoError>

pub fn cur_iv(&self) -> Vec<u8>

Trait Implementations

impl<C, IV> Cipher for OFB<C, IV> where
    C: Cipher,
    IV: InitialVec<C>, 

type Output = usize

fn block_size(&self) -> Option<usize>

The cryptography algorithm used data block size(in bytes) for plaintext, None means that there is no requirement for the data block size.

fn encrypt(
    &self,
    dst: &mut Vec<u8>,
    plaintext_block: &[u8]
) -> Result<usize, CryptoError>

To encrypt the data_block and output the encrypted data dst, the length in bytes of the encrypted data will return if encrypt success, otherwise CryptoError returned.

fn decrypt(
    &self,
    dst: &mut Vec<u8>,
    cipher_block: &[u8]
) -> Result<usize, CryptoError>

To decrypt the cipher_block and output the decrypted data dst, the length in bytes of the decrypted data will return if decrypt success, other CryptoError returned.

impl<C, IV> Clone for OFB<C, IV> where
    C: Cipher + Clone,
    IV: InitialVec<C> + Clone, 

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
