Class DecryptTransform

java.lang.Object
oracle.security.xmlsec.transform.XSTransformer
oracle.security.xmlsec.transform.DecryptTransform

public class DecryptTransform

extends XSTransformer

Internal use only. Applies the XML Decryption Transform.

Note: This transform relies on proper configuration of the KeyRetriever facilities so that decryption keys may be obtained using the contents of any dsig:KeyInfo elements found in the xenc:EncrypteData.

Constructor Detail

DecryptTransform

public DecryptTransform(XSAlgorithmIdentifier trans)

Creates a new DecryptTransform instance.

Parameters:

trans - A XSAlgorithmIdentifier object containing an optional list of dcrpt:Except elements.

Throws:

java.lang.IllegalArgumentException - If the XSAlgorithmIdentifier is not a valid Decryption Transform.

Method Detail

getAlgorithmURI

public java.lang.String getAlgorithmURI()

Description copied from class: XSTransformer

Returns the URI string identifying the Transform algorithm.

Specified by:

getAlgorithmURI in class XSTransformer

Returns:

This Transform's URI string.

transform

protected XMLContainer transform(XMLContainer source)
                          throws TransformationException

Applies a Decryption transformation to the given XMLContainer and returns the result in a new XMLContainer.

Specified by:

transform in class XSTransformer

Parameters:

source - A XMLContainer on which the transform will operate.

Returns:

A XMLContainer containing the transform result, which will be a node-set if the algoritym URI is XMLURI.alg_decryptXML, or an octet stream if the algorithm URI is XMLURI.alg_decryptBinary.

Throws:

TransformationException - If an error occurs during the transformation process.
