In programming, a cipher suite is referred to in both plural and non-plural forms. Each one has different definitions: CipherSuite cipher_suites a list of the cryptographic options supported by the client. [21] An example of how cipher_suites is usually used during the handshake process:
The table below shows the support of various stream ciphers. Stream ciphers are defined as using plain text digits that are combined with a pseudorandom cipher digit stream. Stream ciphers are typically faster than block ciphers and may have lower hardware complexity, but may be more susceptible to attacks.
A client sends a ClientHello message specifying the highest TLS protocol version it supports, a random number, a list of suggested cipher suites and compression methods. The server responds with a ServerHello message, containing the chosen protocol version, a random number, cipher suite and compression method from the choices offered by the client.
Required components for NSA Suite B Cryptography (RFC 6460) are: Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits. For traffic flow, AES should be used with either the Counter Mode (CTR) for low bandwidth traffic or the Galois/Counter Mode (GCM) mode of operation for high bandwidth traffic (see Block cipher modes of ...

There are several cipher suites: The first set of ciphersuites use only symmetric key operations for authentication. The second set use a Diffie–Hellman key exchange authenticated with a pre-shared key. The third set combine public key authentication of the server with pre-shared key authentication of the client.

In Transport Layer Security (TLS), cipher suites based on Diffie–Hellman key exchange (DHE-RSA, DHE-DSA) and elliptic curve Diffie–Hellman key exchange (ECDHE-RSA, ECDHE-ECDSA) are available. In theory, TLS could choose appropriate ciphers since SSLv3, but in everyday practice many implementations refused to offer forward secrecy or only ...
