Hi Shadman, actually I don't think (or at least don't know if) there's a way of decyrpting md5 encrypted text. If you are asking this in order to use it in login forms you encrypt the password field in the form and then you compare it with the user's encrypted one in the db. If there is exact match then that person person is authorized. Best, Emrah Hi, this is Shadman I have problem in encryption and decryption of any text I did encryption of text by MD5 function like $nam = md5("Shadman"); echo $nam; But how I can decrypt if any body did that or have some idea plzzzzzz send me as soon an possible i search that alot.........
