Struct gost_modes::GostCfb[−][src]

pub struct GostCfb<C, M = <C as BlockCipher>::BlockSize, S = <C as BlockCipher>::BlockSize> where
    C: BlockCipher + BlockEncrypt + NewBlockCipher,
    C::BlockSize: IsLessOrEqual<U255>,
    M: Unsigned + ArrayLength<u8> + IsGreaterOrEqual<C::BlockSize> + Sub<C::BlockSize>,
    S: Unsigned + ArrayLength<u8> + IsGreater<U0> + IsLessOrEqual<C::BlockSize>,
    Diff<M, C::BlockSize>: ArrayLength<u8>,  { /* fields omitted */ }

Cipher feedback (CFB) mode of operation as defined in GOST R 34.13-2015

Type parameters:

  • C: block cipher.
  • M: nonce length in bytes. Default: block size.
  • S: number of block bytes used for message encryption. Default: block size.

With default parameters this mode is fully equivalent to the Cfb mode defined in the cfb-mode crate.
