decode

[prokhaled]

How can I decode any string I mean change string to something like (53fhf56934tpiojdeg98345jr) until no one can understand it

and how can I back this string (53fhf56934tpiojdeg98345jr) to the true word

Use

string md5 ( string str)

When encrypted using MD5 there is no way of getter the orginal word back.

What you do, if you tring yo make a log in of some kind, do

$pass = md5($_REQUEST[pass]);

If $pass == "the encrypted version of the password" {

}

That What I need , Thank you too much.

Note: there is not any way to back string . I hope that until no one can know password until if he have it after decode.

it would take someone a very very very long time (years) to decrypt MD5. Infact Vbulliten uses it. So even the admins and mods dont know your real password just the encrypted garbage

[prokhaled]

in user TABLE in the Vbulliten forums it's relly use MD5 to save password in the PASSWORD field but I want to ask how forum send me my username and password if I forget them

I mean
password is saved decoded in databse .. how this forum back password and send it to my E-amil when I forget it. ??????

Have you ever lost your password? I does not send you it (becuase it cant), it sends you a temporary password. Then you login with that, and change your password, to whatever.
