Explanation
PPP (Point-to-Point Protocol) natively supports two authentication protocols: PAP (Password Authentication Protocol), which sends credentials in cleartext and is considered weak, and CHAP (Challenge Handshake Authentication Protocol), which uses a three-way challenge-response mechanism with a shared secret so the password is never sent over the wire. Both are defined in RFC 1334 (PAP) and RFC 1994 (CHAP) as PPP authentication options. RIPEMD is a cryptographic hash algorithm. RC4 is a stream cipher. Kerberos is a ticket-based authentication system used in domain environments - none of these are PPP authentication methods.
