“javax.crypto.BadPaddingException: Data must start with zero” exception

I encountered the abovementioned exception while I was decrypting a string.

Below is my code:

import java.security.KeyP         


        

Answer 1

Have you googled? A lot of people have this problem when the key to encrypt is not the same as the key to decrypt. It seems like you generate new keys all the time instead of using the same key to decrypt that you used for encryption.
