--------------------------------

             Summary: org.apache.ws.security.message.WSSecSignature can't support custom provider
                 Key: WSS-558
                 URL: https://issues.apache.org/jira/browse/WSS-558
             Project: WSS4J
          Issue Type: Bug
          Components: WSS4J Core
    Affects Versions: 1.6.18
            Reporter: Sergey Smith
            Assignee: Colm O hEigeartaigh
            Priority: Minor


WSSecSignature().init not flexible to use custom java.security.Provider
Which leads to the exceptions to use non-standard implementations of encryption algorithms

Current code:
{code:title=WSSecSignature.java|borderStyle=solid}

    public WSSecSignature() {
        super();
        init();
    }
    
    public WSSecSignature(WSSConfig config) {
        super(config);
        init();
    }
    
    private void init() {
        // Try to install the Santuario Provider - fall back to the JDK provider if this does
        // not work
        try {
            signatureFactory = XMLSignatureFactory.getInstance("DOM", "ApacheXMLDSig");
        } catch (NoSuchProviderException ex) {
            signatureFactory = XMLSignatureFactory.getInstance("DOM");
        }
        try {
            keyInfoFactory = KeyInfoFactory.getInstance("DOM", "ApacheXMLDSig");
        } catch (NoSuchProviderException ex) {
            keyInfoFactory = KeyInfoFactory.getInstance("DOM");
        }
    }
{code}

My example of solution:
{code:title=WSSecSignature.java|borderStyle=solid}
    public CustomWSSecSignature() {
        super();
        init(null);
    }
    
    public CustomWSSecSignature(Provider povider) {
        super();
        init(povider);
    }
    
    private void init(Provider povider) {
    	if (povider == null)
    		try {
    			// Try to install the Santuario Provider - fall back to the JDK provider if this does
    			// not work
    			signatureFactory = XMLSignatureFactory.getInstance("DOM", "ApacheXMLDSig");
    		} catch (NoSuchProviderException ex) {
    			signatureFactory = XMLSignatureFactory.getInstance("DOM");
    		}
    	else
    		signatureFactory = XMLSignatureFactory.getInstance("DOM", povider);
    	KeyInfoFactory keyInfoFactory = signatureFactory.getKeyInfoFactory();
    }
{code}

It will be very useful to use in vss4j
