The Net Direct client is an SSL VPN

Passphrases differ from passwords
only in length. Passwords are usually
short, from six to ten characters.
Short passwords may be adequate
for logging onto computer systems
that are programmed to detect a large
number of incorrect guesses, but they
are not safe for use with encryption
systems. Passphrases are usually
much longer—up to 100 characters
or more. Their greater length makes
passphrases more secure.

well as both private and public key
methods. Keys and certificates are
often stored in the PEM format.
A utility used to determine whether a

A standard for storing private keys and
