certificate is selected its name appears in the drop-down list. If the required certificate is not in the list, it must be

MS CHAP v2 is a password based, challenge response, mutual authentication protocol that
uses the industry standard Message Digest 4 (MD4) and Data Encryption Standard (DES)
algorithms to encrypt responses. The authenticating server challenges the access client and the
access client challenges the authenticating server. If either challenge is not correctly answered,
the connection is rejected. MS CHAP v2 was originally designed by Microsoft as a PPP
authentication protocol to provide better protection for dial-up and virtual private network (VPN)
connections. With Windows XP SP1, Windows XP SP2, Windows Server 2003, and Windows
2000 SP4, MS CHAP v2 is also an EAP type.
Password Authentication Protocol (PAP), has two variations PAP and CHAP PAP. It verifies a
user name and password for PPP Internet connections, but it is not as secure as CHAP, since it
works only to establish the initial link. PAP is also more vulnerable to attack because it sends
authentication packets throughout the network. Nevertheless, PAP is more commonly used than
CHAP to log in to a remote host like an Internet service provider.
Message Digest-5 (MD5) is an authentication algorithm developed by RSA. MD5 generates a
128-bit message digest using a 128-bit key, IPSec truncates the message digest to 96 bits.
