Class ESSReceipt

java.lang.Object
oracle.security.crypto.cms.CMSContentInfo
oracle.security.crypto.cms.ESSReceipt

All Implemented Interfaces:

oracle.security.crypto.asn1.ASN1Object, oracle.security.crypto.util.Streamable

public class ESSReceipt

extends CMSContentInfo

This class encapulates a CMS object of content type Receipt.

It is used to send secure digital receipts as part of the S/MIME Enhanced Security Services (RFC-2634).

Constructor Summary

ESSReceipt()
Creates an empty ESSReceipt.

ESSReceipt(oracle.security.crypto.asn1.ASN1ObjectID contentType, byte[] signedContentIdentifier, byte[] originatorSignatureValue)
Creates a ESSReceipt.

ESSReceipt(java.io.InputStream is)
Creates a ESSReceipt, by reading a BER encoding from the given input stream.

Method Summary

protected byte[]	getExposedContent() Returns the contents octets of the DER encoding of the content field of this CMS object.
byte[]	getOriginatorSignatureValue() Return the signature value of the message that triggered the generation of this receipt.
oracle.security.crypto.asn1.ASN1ObjectID	getReceiptContentType() Returns the content type of the message that triggered the generation of this receipt.
byte[]	getReceiptData() Returns the encoded receipt.
byte[]	getSignedContentIdentifier() Returns the signed content identifier of the message that triggered the generation of this receipt.
void	inputContent(java.io.InputStream is) Initialize this object by reading the BER encoding from the specified input stream.
boolean	isDetached() Indicate if this object is detached.
protected void	setExposedContent(byte[] expContent) Returns the contents octets of the DER encoding of the content field of this CMS object.
java.lang.String	toString() Returns a brief text description of this object.
protected void	update() Clears the internal output cache.

Constructor Detail

ESSReceipt

public ESSReceipt()

Creates an empty ESSReceipt.

ESSReceipt

public ESSReceipt(oracle.security.crypto.asn1.ASN1ObjectID contentType,
                  byte[] signedContentIdentifier,
                  byte[] originatorSignatureValue)

Creates a ESSReceipt.

Parameters:

contentType - The content type identifier.

signedContentIdentifier - The signed content identifier.

originatorSignatureValue - The signature value.

ESSReceipt

public ESSReceipt(java.io.InputStream is)
           throws java.io.IOException

Creates a ESSReceipt, by reading a BER encoding from the given input stream.

Parameters:

is - The input stream.

Throws:

java.io.IOException - If the input is not correctly formatted or an I/O exception occurs while reading from the input stream.

Method Detail

setExposedContent

protected void setExposedContent(byte[] expContent)

Description copied from class: CMSContentInfo

Returns the contents octets of the DER encoding of the content field of this CMS object. The value returned is suitable for input to the "message-digesting" and "content-encryption" process of RFC-2630.

Specified by:

setExposedContent in class CMSContentInfo

See Also:

CMSContentInfo.isDetached()

getExposedContent

protected byte[] getExposedContent()

Description copied from class: CMSContentInfo

Returns the contents octets of the DER encoding of the content field of this CMS object. The value returned is suitable for input to the "message-digesting" and "content-encryption" process of RFC-2630.

Specified by:

getExposedContent in class CMSContentInfo

Returns:

The contents octets or null for a detached CMS object.

See Also:

CMSContentInfo.isDetached()

isDetached

public boolean isDetached()

Indicate if this object is detached.

This method returns true only for an empty ESSReceipt object which is not allowed by RFC-2634.

Specified by:

isDetached in class CMSContentInfo

Returns:

true if detached; false otherwise.

See Also:

CMSContentInfo.isDetached()

getReceiptContentType

public oracle.security.crypto.asn1.ASN1ObjectID getReceiptContentType()

Returns the content type of the message that triggered the generation of this receipt.

Returns:

The content type identifier.

getSignedContentIdentifier

public byte[] getSignedContentIdentifier()

Returns the signed content identifier of the message that triggered the generation of this receipt.

Returns:

The signed content identifier.

getOriginatorSignatureValue

public byte[] getOriginatorSignatureValue()

Return the signature value of the message that triggered the generation of this receipt.

Returns:

The original signature value.

getReceiptData

public byte[] getReceiptData()
                      throws java.io.IOException

Returns the encoded receipt.

Returns:

Byte Array containing the Receipt.

Throws:

java.io.IOException

toString

public java.lang.String toString()

Returns a brief text description of this object.

Overrides:

toString in class java.lang.Object

Returns:

A string description this object.

inputContent

public void inputContent(java.io.InputStream is)
                  throws java.io.IOException

Initialize this object by reading the BER encoding from the specified input stream.

Specified by:

inputContent in class CMSContentInfo

Parameters:

is - The input stream.

Throws:

java.io.IOException - An I/O error occurred or the object encoding was incorrect.

update

protected void update()

Clears the internal output cache. This method is called automatically if the object ever changes, so API users need not be concerned with it. Implementors of subclasses, however, do need to ensure that it gets called when appropriate.

Overrides:

update in class CMSContentInfo
