Challenge

public Challenge(oracle.security.crypto.core.AlgorithmIdentifier digestAlg,
                 java.math.BigInteger randomInt,
                 oracle.security.crypto.cert.GeneralName sender,
                 oracle.security.crypto.core.PublicKey pubKey)
          throws oracle.security.crypto.core.AlgorithmIdentifierException,
                 oracle.security.crypto.core.InvalidKeyException,
                 oracle.security.crypto.core.CipherException

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.

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.

Challenge

public Challenge(byte[] witness,
                 java.math.BigInteger randomInt,
                 oracle.security.crypto.cert.GeneralName sender,
                 oracle.security.crypto.core.PublicKey pubKey)
          throws oracle.security.crypto.core.AlgorithmIdentifierException,
                 oracle.security.crypto.core.InvalidKeyException,
                 oracle.security.crypto.core.CipherException

Create a new Challenge instance using the given witness digest bytes, challenge random integer and sender's name, and encrypts the challenge using the given public key. The digest algorithm will be left null, in keeping with the CMP protocol.

Parameters:

witness - The digest of the challenge random integer's 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.
