示例1: getSigningCertFromJar
import java.util.jar.JarEntry; //导入方法依赖的package包/类
/**
* FDroid's index.jar is signed using a particular format and does not allow lots of
* signing setups that would be valid for a regular jar. This validates those
* restrictions.
*/
X509Certificate getSigningCertFromJar(JarEntry jarEntry) throws SigningException {
final CodeSigner[] codeSigners = jarEntry.getCodeSigners();
if (codeSigners == null || codeSigners.length == 0) {
throw new SigningException(repo, "No signature found in index");
}
/* we could in theory support more than 1, but as of now we do not */
if (codeSigners.length > 1) {
throw new SigningException(repo, "index.jar must be signed by a single code signer!");
}
