我正在开发一个
Android项目.我有一个PEM证书字符串：
-----BEGIN CERTIFICATE----- MIIEczCCA1ugAwIBAgIBADANBgkqhkiG9w0BAQQFAD..AkGA1UEBhMCR0Ix EzARBgNVBAgTClNvbWUtU3RhdGUxFDASBgNVBAoTC0..0EgTHRkMTcwNQYD VQQLEy5DbGFzcyAxIFB1YmxpYyBQcmltYXJ5IENlcn..XRpb24gQXV0aG9y ...MANY LINES... It8una2gY4l2O//on88r5IWJlm1L0oA8e4fR2yrBHX..adsGeFKkyNrwGi/ 7vQMfXdGsRrXNGRGnX+vWDZ3/zWI0joDtCkNnqEpVn..HoX -----END CERTIFICATE-----
(我将上面的证书字符串分配给名为CERT_STR的变量)
我将以上PEM字符串转换为X509Certificate：
byte[] certBytes = CERT_STR.getBytes();
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
InputStream certIs = new ByteArrayInputStream(certBytes);
// now I get the X509 certificate from the PEM string
X509Certificate certificate = (X509Certificate) certificateFactory.generateCertificate(certIs);
然后,我尝试通过以下方式以编程方式安装证书：
Intent intent = KeyChain.createInstallIntent(); // because my PEM only contains a certificate,no private key,so I use EXTRA_CERTIFICATE intent.putExtra(KeyChain.EXTRA_CERTIFICATE,certificate.getEncoded()); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent);
当我运行我的应用程序时,我看到系统对话框弹出“Extracting …”,我知道系统正在提取我的证书,但该对话框始终显示“Extracting …”.
为什么？我的代码安装证书在哪里错了？
解决方法
您可能没有使用正确创建的X509证书.以下工作结束,我没有看到任何“提取…”对话框(Nexus 5X,Android 7.0)：
String x509cert = "-----BEGIN CERTIFICATE-----\n" +
"MIICrjCCAhegAwIBAgIJAO9T3E+oW38mMA0GCSqGSIb3DQEBCwUAMHAxCzAJBgNV\n" +
"BAYTAlVaMREwDwYDVQQHDAhUYXNoa2VudDENMAsGA1UECgwERWZpcjEQMA4GA1UE\n" +

"B7x2HND9LU/iz02ugGJ8vwg8\n" +
"-----END CERTIFICATE-----\n";
Intent intent = KeyChain.createInstallIntent();
intent.putExtra(KeyChain.EXTRA_CERTIFICATE,x509cert.getBytes());
startActivity(intent);
为了生成上述证书,我使用了以下步骤(基于Generating Keys and Certificates for SSO)：
$openssl genrsa -out rsaprivkey.pem 1024 $openssl req -new -x509 -key rsaprivkey.pem -out rsacert.pem $ls rsacert.pem rsaprivkey.pem
然后我只需将cat rsacert.pem的输出复制/粘贴到x509cert.
希望这可以帮助.
