And Another One: Part Fifteen — JarEntry.getCertificates And JarVerifier.getCertificates

Having read the contents of the file in the JAR the PackageParser.loadCertificates method returns the result of calling getCertificates on the given JarEntry.





    public Certificate[] getCertificates() {
        if (parentJar == null) {
            return null;
        JarVerifier jarVerifier = parentJar.verifier;
        if (jarVerifier == null) {
            return null;
        return jarVerifier.getCertificates(getName());


The JarEntry getCertificates method is effectively a wrapper around the JarVerifier getCertificates method.





    Certificate[] getCertificates(String name) {
        Certificate[] verifiedCerts = verifiedEntries.get(name);
        if (verifiedCerts == null) {
            return null;
        return verifiedCerts.clone();

The JarVerifier getCertificates method returns a copy of the array of certificates, if any, found in the verifiedEntries Hashtable.

As we have seen the certificates would have been added by the verify method when it was called on the
JarVerifier.VerifierEntry associated with the given member of the JAR.
