First, I have openvpn working just fine, between the website and the forums, I got what I needed, so that's great.
I've got the following in my config file:
Code: Select all
cipher AES-256-CBC
tls-cipher DHE-RSA-AES256-SHACode: Select all
openvpn --show-tls
Available TLS Ciphers,
listed in order of preference:
DHE-RSA-AES256-SHA
DHE-DSS-AES256-SHA
AES256-SHA
EDH-RSA-DES-CBC3-SHA
EDH-DSS-DES-CBC3-SHA

openvpn --show-ciphers
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.

openvpn --show-digests
The following message digests are available for use with
OpenVPN. A message digest is used in conjunction with
the HMAC function, to authenticate received packets.
You can specify a message digest as parameter to
the --auth option.
