    • SignatureHeaderBlock

      public SignatureHeaderBlock(jakarta.xml.soap.SOAPElement elem) throws XWSSecurityException
      parse and create the Signature element
      Parameters:
      elem - the element representing an XML Signature NOTE : this constructor assumes a fully initialized XML Signature No modifications are allowed on the signature, We can only get existing values. For example appendObject() would throw an Exception. If a KeyInfo was not present in the signature, then calling getKeyInfo() will not append a KeyInfo child to the signature.
      Throws:
      XWSSecurityException

    • SignatureHeaderBlock

      public SignatureHeaderBlock(org.apache.xml.security.signature.XMLSignature signature) throws XWSSecurityException
      constructor that takes Apache Signature
      Parameters:
      signature - the XMLSignature from XML DSIG NOTE : No modifications are allowed on the signature, if a SIGN operation has already been performed on the argument signature. We can only get existing values. For example appendObject() would throw an Exception. If a KeyInfo was not present in the signature, then calling getKeyInfo() will not append a KeyInfo child to the signature.
      Throws:
      XWSSecurityException

    • SignatureHeaderBlock

      public SignatureHeaderBlock(Document doc, String signatureMethodURI) throws XWSSecurityException
      This creates a new ds:Signature Element and adds an empty ds:SignedInfo. The ds:SignedInfo is initialized with the specified Signature algorithm and Canonicalizer.ALGO_ID_C14N_EXCL_OMIT_COMMENTS which is RECOMMENDED by the spec. This method's main use is for creating a new signature.
      Parameters:
      doc - The OwnerDocument of signature
      signatureMethodURI - signature algorithm to use.
      Throws:
      XWSSecurityException
