WebSome modes (like CTR) effectively turn a block cipher into a stream cipher. The widespread consensus is that ciphers that provide only confidentiality, without any form of authentication, are undesirable. Instead, primitives have been defined to integrate symmetric encryption and authentication (MAC). For instance:
