[vpn] VPN - encryption

[Christopher Gripp]

The two are independant of eachother.  Although, a VPN without
encryption isn't very secure, it has it's purposes.  Many VPN
implementations include a NULL encryption option.  The most common
encryption used with VPNs is 3DES w/ either MD5 or SHA1 hashing.  I am
starting to see some vendors add AES(Rijndael) to their choice of
algorithms.

Hi
I've read a bit about VPN on different sites. My question is :
What is the relation between VPN and encryption? Is it possible to
have VPN without encryption? is encryption with VPN optional or a
must?

Best regards,
Ranj
