hi
thanks for your answer
i want generate a one time password that is valid for my server and encrypt it
when server recives password , decrypts password and then it authenticates it (by an algorythm between client and server) , if decrypted password is valid , save URL values to its database.
i save recived password to server database , and when someone send again that password , i search in database and when i found that password ,message it "Password Not Valid" ..
is there any way to encrypt password ?
