           Summary: Cannot generate with the same key but different
                    algorithms
           Product: Security
           Version: Java 1.3
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: PatchAvailable
          Severity: major
          Priority: P2
         Component: Signature
        AssignedTo: security-dev@xml.apache.org
        ReportedBy: [EMAIL PROTECTED]


If you issue a second signature but with different algorithm, e.g., RSAWithSHA1
for the first signature, and RSAWithRipeMD160 for the second, you will get the
exception that says:
 org.apache.xml.security.signature.XMLSignatureException: object not initialized
for signature or verification
Original Exception was java.security.SignatureException: object not initialized
for signature or verification

This problem is caused by the initSign method in class SignatureAlgorithm:
[1]   public void initSign(Key signingKey) throws XMLSignatureException {       
   
[2]        initializeAlgorithm(true);
[3]         if (keysSigning.get()==signingKey) {
[4]        return;
[5]       }
[6]       keysSigning.set(signingKey);
[7]        this._signatureAlgorithm.engineInitSign(signingKey);
[8]   }
The lines 3-5 should be commented to solve above problem.
