Re: CISCO MD5 encryption

Ok...

1- MD5 is considered insecure and you can create collisions. (This doesn't mean it's suddenly obsolete, but there *is* 
weakness.)

2- Cisco utilizes MD5 hashing to store passwords in configs.

The problem here is I haven't seen anyone draw the lines between the weakness in MD5 and how it matters to Cisco's 
usage of it.

Just because you see "MD5" in a statement doesn't mean you can just drop the "don't use, it you're dumb" response. 
Proper security needs more thought than that.

Props to those responses who are knowledgable about the Cisco usage of MD5 and how that relates to the OP's question on 
rainbow tables and how susceptible it may be.
