Symmetric Primitives

Facts and frequently asked questions about symmetric cryptography. Block ciphers, stream ciphers and hash functions are symmetric operations. A symmetric keyed operation is where the sender and receiver share a common key to perform encoding and decoding of a message. Examples include DES and AES. A symmetric unkeyed operation is where the sender and receiver call the same cryptographic operation on a message. For example the SHA hash function.
