byte[]

return the ASN.1 encoded representation of this object.

AlgorithmParameters

Return an AlgorithmParameters object giving the encryption parameters used to encrypt the message content.

String

return the object identifier for the content encryption algorithm.

byte[]

return the ASN.1 encoded encryption algorithm parameters, or null if there aren't any.

return a store of the intended recipients for this message

AttributeTable
