The following ciphers and cipher modes are available
for use with OpenVPN. Each cipher shown below may be
used as a parameter to the --cipher option. The default
key size is shown as well as whether or not it can be
changed with the --keysize directive. Using a CBC mode
is recommended. In static key mode only CBC mode is allowed.
