Class OriginatorPublicKey

java.lang.Object

iaik.cms.OriginatorPublicKey

All Implemented Interfaces:

ASN1Type, KeyIdentifier

public class OriginatorPublicKey
extends java.lang.Object
implements KeyIdentifier

The CMS type OriginatorPublicKey.

The OriginatorPublicKey type is used as one alternative for identifying the public key of the originator within a KeyAgreeRecipientInfo (see CMS Cryptographic Message Syntax, RFC 2630):

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