Synopsis

The ciphers command is used to obtain a list of the ciphers that are supported for the different versions of the SSL protocol. It is primarily useful as a test tool to determine the appropriate cipher lists for the version of the protocol that you wish to use. The command’s output is a list, separated by colons, of the supported cipher strings matching the criteria specified by the command’s options.

Options

-ssl2

Include only the ciphers that are supported by SSLv2.

-ssl3

Include only the ciphers that are supported by SSLv3.

-tls1

Include only the ciphers that are supported by TLSv1.

-v

Produce a more verbose list of cipher strings that includes the protocol version, key exchange, authentication, encryption, and MAC algorithms.

Notes

By default, cipher strings for all of the supported protocol versions are included. Only one of the version options may be specified at a time. Additional arguments on the command line are interpreted either as ciphers to be added to the list or as modifiers to refine the list.
