BadpaddingException

[Venkatesh Kumar]

Hi All:

I am trying to decrypt the data using Blowfish algorithm and am using the same key that was used to encrypt the data.

I am getting the following exception :

javax.crypto.BadPaddingException: Given final block not properly padded

part of the code where i am decrypting the code
-----------------------------------------------
byte[] b =new String("19BA7C8BEEC31234").getBytes();
Cipher decipher = Cipher.getInstance(essoAlgorithm);
decipher.init(Cipher.DECRYPT_MODE, essoKeySpec);
System.out.println("deciphered is " + new String(decipher.doFinal(b)));
-----------------------------------------------

Can anyone throw some light on how to solve the above exception .

Thanks

Are you thinking this treats the string as a hex string, turning it into 8 bytes? If so, sorry but that won't do it. You'll end up with the byte array { 31, 39, 42, 41, 37, 43, ... }

If not, are you sure that "19BA7C8BEEC31234" is a correctly encrypted string for that algorithm?
