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 RFC 5652):

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

Constructor Detail

OriginatorPublicKey

public OriginatorPublicKey()

Empty default constructor.

Used for dynamic object creation only. Shall be not used by an application.

OriginatorPublicKey

public OriginatorPublicKey(java.security.PublicKey publicKey)

Creates a OriginatorPublicKey for the given public key.

Parameters:

publicKey - the public key

OriginatorPublicKey

public OriginatorPublicKey(ASN1Object obj)
                    throws CodingException

Creates an OriginatorPublicKey from an ASN1Object.

Parameters:

obj - the OriginatorPublicKey as ASN1Object

Throws:

CodingException - if the ASN1Object cannot be decoded or is invalid structured

OriginatorPublicKey

public OriginatorPublicKey(ASN1Object obj,
                           SecurityProvider securityProvider)
                    throws CodingException

Creates an OriginatorPublicKey from an ASN1Object.

Parameters:

obj - the OriginatorPublicKey as ASN1Object

securityProvider - the SecurityProvider to be used by this object, if null use the default system-wide installed SecurityProvider; SecurityProvider method getKeyFactory may be required to get a KeyFactory required for parsing the encoded key

Throws:

CodingException - if the ASN1Object cannot be decoded or is invalid structured

Method Detail

Specified by:

toASN1Object in interface ASN1Type

Returns:

this OriginatorPublicKey as ASN1Object

Throws:

CodingException - if this OriginatorPublicKey cannot be represented as ASN.1 object

equals
