ssl_cipher

Name of symmetric cipher to use when no algorithm is specified.

String, read/write

"AES-128-CBC"

This parameter defines the default symmetric cipher used by the crypt I/O driver. The name of a cipher consists in up to 3 components separated by the "-" symbol: the algorithm name ( e.g. aes, bf, des), the key size (when the algorithm may be used with different sizes of keys) and the block chaining mode ( e.g. cbc, cfb1, cfb8, ecb, ofb). For instance, "des-ofb" designates DES with Output Feedback chaining.
Use the command mmssl list cipher to get a full list of the supported cipher names.
