WebJun 6, 2024 · Cipher Modes. Symmetric algorithms can operate in a variety of modes, most of which link together the encryption operations on successive blocks of plaintext and ciphertext. Symmetric block ciphers should be used with one of the following cipher modes: Cipher Block Chaining (CBC) Ciphertext Stealing (CTS) WebWe introduce a new primitive called a block cipher that will let us build more powerful forms of encryption. We will look at a few classic block-cipher constructions (AES and 3DES) and see how to use them for encryption. Block ciphers are the work horse of cryptography and have many applications.
