decrypt password

[patelp7]

Hello.

 

I encryt a password and put it in a table.

 

How would i retrieve the password in a decrypted format?

 

$Encryptedpassword = crypt($Password, "ND");
	$query = "insert into adminmember (Username, Password, First_Name, Last_Name, EmailAdd , User_Level) Values ('$Username', '$Encryptedpassword', '$Firstname', '$Lastname', '$Emailadd', '$Userlevel')";

Thats how mi encrypt it when inserting....any ideas on retrieving?

Cheers

When you validate someones login you just encrpt the password that they type in, im not sure, but i dont think you can get it back to display it.

its for a edit screen....so if they were to edit their password, as it is encrypted the wrong character values will be inserted.  You know what i mean Govner

Hmmm.. im not very good at PHP so im not really sure...

 

If i were to do this id just fetch the password from the database, even if its something like "dfkjb45kjbfokjn45t08hi"

Then to login, compare the password they type in with this one.

 

You have to encrypt the password they type in aswell in order for the validation to work, else you would be validating thier password that could be "apple" to an encrypted apple lol, which could be sopmething like tha above.

 

Even if their changing the password you dont need to know what it was in the first place.
