                       throws AlgorithmIdentifierException

Create a new CBCAlgorithmIdentifier using the given OID, and obtaining the initialization vector by decoding the given ASN1Object.

Parameters:

oid - The object identifier for the cipher algorithm.

params - An ASN1Object containing the encoding of the bytes of the initialization vector.

Throws:

AlgorithmIdentifierException

CBCAlgorithmIdentifier

public CBCAlgorithmIdentifier(ASN1ObjectID oid,
                      byte[] iv)

Create a new CBCAlgorithmIdentifier using the given OID and initialization vector.

Parameters:

oid - The object identifier for the cipher algorithm.

iv - The bytes of the initialization vector.

CBCAlgorithmIdentifier

public CBCAlgorithmIdentifier(AlgorithmIdentifier algID,
                      byte[] iv)

Create a new CBCAlgorithmIdentifier using the OID from the given algorithm identifier and initialization vector.

Parameters:

algID - The algorithm identifier from which to obtain the object identifier for the cipher algorithm.
