                 javax.crypto.BadPaddingException

Create a new Challenge instance using the given digest algorithm, challenge random integer and sender's name, and encrypts the challenge using the given public key.

Note the changes in the method signature

Previously public Challenge (AlgorithmIdentifier , BigInteger , GeneralName , oracle.security.crypto.core.PublicKey)

Nowpublic Challenge (AlgorithmIdentifier , BigInteger , GeneralName , java.security.PublicKey)

Note the change in the exceptions declared to be thrown.

Exceptions no longer thrown -- AlgorithmIdentifierException,CipherException

Exceptions introduced -- java.security.InvalidKeyException ,NoSuchAlgorithmException, NoSuchPaddingException, IllegalBlockSizeException,BadPaddingException

Parameters:

digestAlg - The digest algorithm used to produce the witness digest bytes.

randomInt - The random integer that will be encrypted to form the challenge (with the sender's name).

sender - The sender's name that will be encrypted to form the challenge (with the random integer).

pubKey - The public key of the recipient, which will be used to encrypt the challenge.

Throws:

java.security.NoSuchAlgorithmException
