Challenge-Response authentication

An authentication method for transmitting the CallPilot mailbox number and password to the CallPilot server when a messaging session begins.

CallPilot uses a Challenge-Response method called CRAM-MD5. When a mailbox owner attempts to log on to the CallPilot server, the server sends data to the client software. This data is the "challenge". The client software uses the MD5 algorithm to combine the challenge data with the mailbox logon information and sends this to the server as a "response".

By encoding mailbox passwords, Challenge-Response authentication prevents hackers from obtaining CallPilot logon information.
