A cipher suite is a set of algorithms that help secure a network connection. Suites typically use Transport Layer Security (TLS) or its now-deprecated predecessor Secure Socket Layer (SSL). The set of algorithms that cipher suites usually contain include: a key exchange algorithm, a bulk encryption algorithm, and a message authentication code (MAC) algorithm. The key exchange algorithm is used to exchange a key between two devices. This key is used to WebCiphers, also called encryption algorithms, are systems for encrypting and decrypting data.
