Re: How to validate passwords without storing them anywhere.

I had a program where I encrypted the user's email with his password, then
to check I used the same procedure and compared the result against the
saved one. Using SQL encryption)
After an OS upgrade the program stopped working. A better encryption
algorithm generates different "encrypted data" using the same text and the
same password.

And, even if you knew the word being stored is 'VALID',
just how likely is it to figure out the encryption key used in this

process?

How likely is it that IBM POWER machines become inoperable? And still,
companies opt to have machine level redundancy, extremely costly.


It's the same with security: How far would you go to prevent a very fatal
but extremely unlikely event?

How likely is it that there is a security breach into the VPN
infrastructure, in turn allowing access to all internal servers *including*
IBM i, because credentials have been stored on a private laptop, being
infected by malware, copying "interesting" data back "home"?

How likely is it that on some windows share (being accessible with the
same credentials) are scripts running automatisms, containing passwords in
clear text, allowing an attacker to gain a 5250 login?

How likely is is that this attacker knows enough about IBM i to search for
the central application on that machine and succeeds?

How likely is it that he is able to find and can cpytostmf the login
credentials database, ftp'ing it to that windows machine and in turn upload
it to dropbox or something similar?

Just give it a thought.

:wq! PoC
