Symmetric Encryption. Symmetric encryption (or pre-shared key encryption) uses a single key to both encrypt and decrypt data. Both the sender and the receiver need the same key to communicate. Symmetric key sizes are typically 128 or 256 bitsâthe larger the key size, the harder the key is to crack.
Key-exchange algorithms like KEA and RSA govern the way in which a server and client determine the symmetric keys they use during an SSL session. The most commonly used SSL cipher suites use the RSA key exchange.ipher suites define the following aspects of SSL communication: The key exchange Algorithm. The encryption cipher. The encryption cipher key length. The message authentication method. The SSL protocol supports many ciphers.
