  • Page 12 A hash algorithm is a one-way function that operates on a message of arbitrary length to create a Algorithm fixed-length message digest used by cryptographic services to ensure its data integrity. MD5 has a smaller digest and is considered to be slightly faster than SHA-1. Cisco uses both SHA-1 hashes within our implementation of the IPsec framework.

L2TP merges the older Cisco Layer Two Forwarding (L2F) protocol with PPTP. L2TP can be used with IPsec encryption and is considered more secure against attack than PPTP.
