以下是使用Let's Encrypt生成SSL证书的代码（基于https://github.com/zero11it/acme-client）：
AcmeChallengeListener challengeListener = new HttpChallengeListener(sessionToken, appObjectId, userId, domains[0], "");
Acme acme = new Acme(CA_STAGING_URL, new DefaultCertificateStorage(true), true, true);
X509Certificate cert = acme.getCertificate(domains, AGREEMENT_URL, contacts, challengeListener);
String fullchain = CertificateHelper.x509ToBase64PEMString(cert);
有没有办法获取PrivateKey并将其作为字符串与-----BEGIN PRIVATE KEY-----和-----END PRIVATE KEY-----一起使用？因此，我们的应用程序可以将其上传到我们的NGINX服务器。

解决方案是修改库并公开证书存储，如下所示：
AlertDialog.Builder alt_bld = new AlertDialog.Builder(this, R.style.AlertDialogStyle);
alt_bld.setTitle("Select Date");
try{
final View view = View.inflate(addAlarm.this, R.layout.alert_dialog_radiogroup, null);
radioGroup = (RadioGroup)view.findViewById(R.id.radio);
radioGroup.clearCheck();
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup radioGroup, @IdRes int i) {
//My code to handle checked radio button.
}
});
alt_bld.setView(view);
} catch (Exception e){
e.printStackTrace();
}
//setting +ve and -ve buttons here.
...
AlertDialog alert = alt_bld.create();
alert.show();
此处应用可以获取
public CertificateStorage getCertificateStorage() {
return certificateStorage;
}
