如何通过Android API获取该base64公钥?

最佳答案

要获取公共证书,您需要在代码中使用PackageManager

PackageInfo packageInfo = null;

try {
   packageInfo = getPackageManager().getPackageInfo(getPackageName(),
                                           PackageManager.GET_SIGNATURES);

   Signature[] signatures = packageInfo.signatures;
   byte[] cert = signatures[0].toByteArray();
   InputStream input = new ByteArrayInputStream(cert);

   CertificateFactory cf = CertificateFactory.getInstance("X509");
   X509Certificate c = (X509Certificate)cf.generateCertificate(input);

   PublicKey key = c.getPublicKey();

   ...

} catch ( Exception e) {
        e.printStackTrace();
}

关于android - Android-在应用运行时访问自己的公钥?使用哪个 key 对对apk进行签名,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/18250791/
