本文深入探讨了如何通过解析应用签名和证书来获取关键信息，包括使用PackageManager和CertificateFactory类进行操作，详细解释了获取签名、解析X.509证书以及提取公钥和序列号的过程。

publicvoid getSingInfo() {
        try{
            PackageInfo packageInfo = getPackageManager().getPackageInfo(
                    "wabao.et.master", PackageManager.GET_SIGNATURES);
            Signature[] signs = packageInfo.signatures;
            Signature sign = signs[0];
            parseSignature(sign.toByteArray());
        }catch(Exception e) {
            e.printStackTrace();
        }
    }
 
publicvoid parseSignature(byte[] signature) {
    try{
        CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
        X509Certificate cert = (X509Certificate) certFactory.generateCertificate(newByteArrayInputStream(signature));
        String pubKey = cert.getPublicKey().toString();
        String signNumber = cert.getSerialNumber().toString();
    }catch(CertificateException e) {
        e.printStackTrace();
    }
}
