    Posted: 25 September 2004 at 4:39pm

I would like to get insights from people about something.  I know that it is very useful to encrypt passwords that are stored in a database especially if your database could be downloaded from your web site. However, I have a concern about forgotten passwords. I've heard that people cannot receive their passwords via email if they are encrypted. Is there any way to work around this? Another concern that I have is a person would have to reset his/her password if he or she forgot it.

what you/people ussually do is when someone has forgotten their password.

you then create a new one (random) and send it via email or something....

Interestingly, you can yank passwords literally out of cyberspace since 99% of all emails are sent in plain text. Its very simple to do at the correct places although considering the amount of email flying around including spam, I suppose it isn't too practical. Go and download EtherReal or similar software and let it monitor your traffic. It's especially funny (scary??) when you run it on your LAN if you have one. You'll find out all sorts of nifty things...

I'd have to say I'm for the "email a new password/activation link" and require an immediate password change just for safety....but that's my 2 cents.

Thats insecure IMHO, 90% of the people hacked on MSN will be hacked because someone guessed their secret question (not an official statistic)

Reset password is best I reckon.  Gotta be careful of people reseting other peoples passwords to be a nuisance however.

All encrypts do have a decrypt. It's a matter of knowing what the cypher is.
 
What you could do is send a link via email which will take them to a password change page as thought they had logged in normally (eg, set your password checker to "if 1=1" for that page, or something like that).
 
That or resetting their pass, and sending an autogen pass to them by email. Both have the problems with people plucking them out of cyberspace, but the top one would probably be slightly more secure, as someone interested in random mayhem is less likely to bother following a link and entering new pass and everything, than just using a pass... the difference is marginal however.
 
A better way that plain text would be to send them the password in a .txt file which you had changed the extension of (to something like .dud) and then instruct them to change the extension back to .txt. This is a lot less likely to be picked up by a password sniffer.
