public abstract class OriginatorPublicKey

extends Object

implements OriginatorIdentifierOrKey

A class which holds an originator's public key for use by a recipient to decrypt a CMS EnvelopedData in which a key encrypting key is obtained by key agreement performed with the said public key.

OriginatorPublicKey is primarily intended for use with the Ephemeral-Static Diffie-Hellman algorithm to generate an EnvelopedData, in which the recipient has an identifying certificate but the sender (aka originator) may be anonymous.

OriginatorPublicKey is defined in RFC2630 by the ASN.1 structure

     OriginatorPublicKey ::= SEQUENCE {
        algorithm  AlgorithmIdentifier,
        publicKey  BIT STRING}
