WebThe TLS 1.2 Protocol Handshaking Again (Renegotiation) Cipher Suite Choice and Remote Entity Verification Transport Layer Security (TLS) is the most widely used protocol for implementing cryptography on the web. TLS uses a combination of cryptographic processes to provide secure communication over a network. This section provides an 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.
