encryption

[Anon]

Hi,

I would like to use unique ref numbers to generate keys as passwords for the users first login the page.

I've tried using md5(), but the hash string is 32-digits which is too long. and i also tried to use crypt(), with first 2 digits of ref number as seed, the result string is shorter but with special characters.

How can I generate a 8-12 digits long encrypted string without special characters??

Pls help and thanks in advance.

Since it's a password for the user's first login (therefore a temporary password), you can just get the first 8-12 digits of the md5() hash string. I don't know how secure this is, but since it's a temporary password, it might be secure enough...

$md5string = substr(md5($incomingString), 0, rand(8,12));

will give you a md5'd incoming string with 8-12 characters.

or,

$md5string = substr(md5($incomingString), 0, 8);

for just an 8 char length one.

cheers,
