Method Detail

build

public Document build(Document doc,
                      WSSecHeader secHeader)
               throws WSSecurityException

Throws:

WSSecurityException

prepare

public void prepare(Document doc,
                    WSSecHeader secHeader)
             throws WSSecurityException

Throws:

WSSecurityException

getSignatureElement

public Element getSignatureElement()

Returns the SignatureElement. The method can be called any time after prepare().

Returns:

The DOM Element of the signature.

addReferencesToSign

public List<Reference> addReferencesToSign(List<WSEncryptionPart> references,
                                           WSSecHeader secHeader)
                                    throws WSSecurityException

This method adds references to the Signature.

Parameters:

references - The list of references to sign

secHeader - The Security Header

Throws:

WSSecurityException

computeSignature

public void computeSignature(List<Reference> referenceList)
                      throws WSSecurityException

Compute the Signature over the references. After references are set this method computes the Signature for them. This method can be called any time after the references were set. See addReferencesToSign().

Throws:

WSSecurityException

computeSignature

public void computeSignature(List<Reference> referenceList,
                             boolean prepend,
                             Element siblingElement)
                      throws WSSecurityException

Compute the Signature over the references. After references are set this method computes the Signature for them. This method can be called any time after the references were set. See addReferencesToSign().

Throws:

WSSecurityException

getDerivedKeyLength

protected int getDerivedKeyLength()
                           throws WSSecurityException

Description copied from class: WSSecDerivedKeyBase

The derived key will change depending on the sig/encr algorithm. Therefore the child classes are expected to provide this value.

Specified by:

getDerivedKeyLength in class WSSecDerivedKeyBase

Returns:

the derived key length

Throws:

WSSecurityException

setDerivedKeyLength

public void setDerivedKeyLength(int keyLength)

setSignatureAlgorithm

public void setSignatureAlgorithm(String algorithm)

Set the signature algorithm to use. The default is WSConstants.SHA1.

Parameters:

algorithm - the signature algorithm to use.

getSignatureAlgorithm

public String getSignatureAlgorithm()

Returns:

the signature algorithm to use

getSignatureId

public String getSignatureId()

Returns the the value of wsu:Id attribute of the Signature element.

Returns:

Return the wsu:Id of this token or null if the signature has not been generated.

setDigestAlgorithm

public void setDigestAlgorithm(String algorithm)

Set the digest algorithm to use. The default is WSConstants.SHA1.

Parameters:

algorithm - the digest algorithm to use.

getDigestAlgorithm

public String getDigestAlgorithm()

Returns:

the digest algorithm to use

getSignatureValue

public byte[] getSignatureValue()

Returns:

Returns the signatureValue.

setSigCanonicalization

public void setSigCanonicalization(String algo)

Set the canonicalization method to use. If the canonicalization method is not set then the recommended Exclusive XML Canonicalization is used by default Refer to WSConstants which algorithms are supported.

Parameters:

algo - Is the name of the signature algorithm

getSigCanonicalization

public String getSigCanonicalization()

Get the canonicalization method. If the canonicalization method was not set then Exclusive XML Canonicalization is used by default.

The string describing the canonicalization algorithm.

isAddInclusivePrefixes

public boolean isAddInclusivePrefixes()

setAddInclusivePrefixes

public void setAddInclusivePrefixes(boolean addInclusivePrefixes)
