Re: CISCO MD5 encryption

[Daniel M Daloia Jr <daniel.daloia () yahoo com>]

There is more than just password security to securing Cisco devices. Start with physical security: if someone has 
physical access to your switches, it doesn't really matter what your password is. If you are concerned with 
Authentication in particular , start looking into TACACS or Radius. Cisco's CCNA Security documentation is good start 
for Cisco's views.

Not sure which model switch you have, but MD5 encrypted passwords on the
Cisco devices use the Unix crypt() scheme which uses a salt. Check your
config, and if your hash begins with $1$ then a salt was used.
