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

Question

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

Below is my code:

import java.security.KeyPair;
import java.security.KeyP         


        

Answer 1

I was getting this error and it turned out in my case to be that the base 64 string I was sending as a parameter contained some characters that were being altered because of being in a URL. The solution turned out to be URL encoding the parameter.
