Issue Description
What Are the Features of PAP and CHAP?
Solution
PAP is short for Password Authentication Protocol. It supports 2-way handshake and transmits the password in plain text. The peer end controls the connection request. PAP cannot effectively prevent attacks.

CHAP is short for Challenge Handshake Authentication Protocol. It supports 3-way handshake and transmits the password in cipher text. CHAP effectively prevents repeated trial-and-error attacks.
