Struct gost_modes::GostCbc

pub struct GostCbc<C, P = GostPadding, Z = U1> where
    C: BlockCipher + NewBlockCipher,
    C::BlockSize: IsLessOrEqual<U255>,
    Z: ArrayLength<Block<C>> + Unsigned + Mul<C::BlockSize> + IsGreater<U0> + IsLessOrEqual<U255>,
    Prod<Z, C::BlockSize>: ArrayLength<u8>,
    P: Padding,  { /* fields omitted */ }

Cipher Block Chaining (CBC) mode of operation as defined in GOST R 34.13-2015

Type parameters:

• C: block cipher.
• P: padding algorithm. Default: GostPadding.
• Z: nonce length in block sizes. Default: 1.

With default parameters this mode is fully equivalent to the Cbc mode defined in the block-modes crate.
