hi..i m facing most of the same problem as u. my problem is that, i've taken any random number and encrypt it through md5 and store it in the database.. but while changing password, when i want to check that random number with that encrypted password(i've encrypted the random number) then the encryption of the random number is not same as that one which is stored in database. while checking, i m giving the random number through text box. i think(with my a bit knowledge), encryption of value of a variable will not be same as encryption of the same value entered by the textbox. it can be some database problem also....i dont know.... i m sure that my coding is correct
