Java program to verify digital signature signed by signtool

问题

I have digitally signed a file(either .exe or .dll not a jar file) using SignTool. Signtool can also verify the digital signature. But my requirement is to check digital signature of file signed by signtool using java program.

I searched on internet but didn't find any info. Could you please give me pointers regarding the same?

Thanks for your suggestion.

Signing Code

jarsigner -keystore c:/my.keystore -storepass ozziepassword e:/securityApplet.jar ozzie

Verify Code:

jarsigner -verify e:/securityApplet.jar

To verify signature:

   Signature signer = null;
    try {
        signer = Signature.getInstance("SHA1withRSA");
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
        return "Verify : No Such Algorith Exception." + e.getMessage();
    }
    try {
        result = signer.verify(digitalSignature);
    } catch (SignatureException e) {
        e.printStackTrace();
        return "Verify : Signature Exception." + e.getMessage();

    }
