Creating a Secure RD Gateway is a great thing, so you can access the internal remote access host server directly from the public network environment.
The material needed to build this secure RD Gateway is the RD gateway itself, as well as a certificate. Because typically these servers behind the RD Gateway are resource servers within the enterprise, the request certificate can use the self-

In the previous article, we talked about the Signing Method of Multi-CN using OpenSSL to sign multi-domain name certificates. In actual use, we encountered a problem. In Android, the browser does not recognize multi-CN domain names, "The certificate name does not match the server name" will be repo

Many may have the same deep experience as myself. Using the OpenSSL library to write an encrypted communication process, the code can be easily written, but the entire work has taken several days. In addition to compiling the program successfully (no certificate file can be used, it is compiled successfully, it cannot run,

I. Reasons
1. If the apk is published online, the default debug. keystore signature has security issues. Therefore, you must write your own signature.
Ii. Functions of signatures
Make sure that this apk is mine. Other applications with the same package name cannot be replaced if the signatures are different.
Iii. Methods
Method 1: Use the keytool.exe tool
default_ca. Its value is the name of the segment that saves the default configuration of CA. Here it is ca_default. This means that when OpenSSL generates a certificate, it will go to the ca_default field to find the corresponding configuration information.
The OpenSSL command allows multiple CA configurations in a configuration file.

If you want to create a self-signed certificate that is not valid for one year, or provide additional information about yourself, you can use Open SSL to create a certificate, instead of the standard tool that comes with the SDK: makekeys.

Different certificates are stored in different formats (such as whether the public key or private key is encrypted for storage, a single certificate, or multiple certificates), and are encoded differently (der/base64) different standards (such as PEM/PKCS), so although the X.509 standard specifies the certificate content specification, the certificate files are s

MQTT serves as the push message pushing protocol for Android clients. The Android client needs to connect to the MQTT Proxy server via SSL/TLS for encrypted transmission of messages. Implementing this process requires two support, one for the MQTT protocol client and the other for the MQTT proxy server. There are many open-source Mqtt proxy servers, and I choose to use Mosquitto Broker.
