Traits used to define functionality of block ciphers and modes of operation.

§About block ciphers

Block ciphers are keyed, deterministic permutations of a fixed-sized input “block” providing a reversible transformation to/from an encrypted output. They are one of the fundamental structural components of symmetric cryptography.

Structs§

  • BlockCtx 🔒
    Closure used in methods which operate over separate blocks.
  • BlocksCtx 🔒
    Closure used in methods which operate over slice of blocks.

Traits§

  • ArrayLength
    Trait making GenericArray work, marking types to be used as length of an array
  • BlockBackend
    Trait implemented by block cipher encryption and decryption backends.
  • BlockCipher
    Marker trait for block ciphers.
  • BlockClosure
    Trait for BlockBackend users.
  • BlockDecrypt
    Decrypt-only functionality for block ciphers.
  • BlockDecryptMut
    Decrypt-only functionality for block ciphers and modes with mutable access to self.
  • BlockEncrypt
    Encrypt-only functionality for block ciphers.
  • BlockEncryptMut
    Encrypt-only functionality for block ciphers and modes with mutable access to self.
  • BlockSizeUser
    Types which process data in blocks.
  • Unsigned
    The marker trait for compile time unsigned integers.
