Description
MS CHAP v2 Microsoft Challenge Handshake Authentication Protocol version 2 (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.
TLS EAP TLS is used during phase 2 of the authentication process. This method uses a user
certificate to authenticate.
