Hi,

Would it be a good idea to start encrypting the user passwords? Not only for someone who hijacks the database but also for the forum operator who can't inadvertertly see the passwords used.

this is a good idea, however with having it where admin's can not see the passwords, i dont think it should be something that is looked into. the reason for this is most peopel that use this forum learn asp so they can edit the forum. with enough playing around, they can figure out how to decode the passwords eazy

Not really.

I encrypt passwords in some VB apps in the database using xp's. There are component-based encryptions for asp, but I haven't found a good script only one yet.

Currently the passwords are quite easy to see, even if you're not interested in them. It would be better if they we're obscured. Also, encryption would make it a bit more difficult to gain access to the passwords by unauthorized persons.

My major point is that passwords should not be EASY viewable. I understand that somebody with complete control can gain access to them anyway, but that is not a major problem to me.

I wouldn't mind looking into encrypting my passwords on the site, I've also thought about encrypting the passwords that are wrote to the cookies too.

I'm working on it... I will release a Security MOD really soon... Using many encryption technologies, and in ASP only, no COM, no external program.

But, I have some difficulty, cause usualy good encryption technic use Memory Movement, and in ASP you can't.

So I'm working on alternate way to do this, without to much losing speed. I know that it will be use on small string, but it might be used for others task later like encrypting private message.

One way encryption (MD5) for PW.
Blowfish encryption for Cookies.


You will be able to use the two encryption for any others parts of you site, like Private message...

Time, I'm not sure, don't have much time on hand for now... And because Blowfish use binary transformation, it a little more difficult to do in in ASP. C, C++ is easy... VB can is medium, but VBScript is missing some usefull function.

wow, can i enc the email address field or what ever other field?
if i enc email addr, how it would affect email funtion, eg. when using a mailling list like feature, maybe email all (1000+members)?

is it possible to use c++ to write one first since it's easy, for those who can upload components?

this would be a Great add on for snitz.

Simple XOR... It easy when you know the text and the encrypt text, to find the KEY.

It's big, so it can take sometime... But in about 3-4 hours, no problem.

You gonna have to decrypt all e-mail... But It can be put in the general e-mail function, so without too much problem you can add it.

Hum, cause SNITZ don't use any components I want to do it in ASP first... After I might do a Component version with more encriptions (BLOWFISH, TWOFIST, DES, 3DES for exemple).
