Re: CISCO MD5 encryption

[César García <celord () gmail com>]

Hi all,  great to see al the feedback from my question, In fact , my
original question came after reading the HBGary Hack and after reading
en email from an outsourcing company sending me a "show run" dump from
a CISCO switch, I wonder if I were unethical ( thing that I'am not )
could I get the password ?

According to some answers It is possible right ? so, I should ask the
company to erase those lines next time in order to avoid any problem
when they send a show run.

Thanks to all !!!
