You have to make a distinction between SSL/TLS and the x509-based certificate authority infrastructure used in combination with SSL/TLS on the Internet. Secure RESTful api communication between multiple servers. If the client is a browser you're stuck with the default config of SSL. This technique is from the javax.net.ssl package and we used it here to implement certificate pinning. Enabling TLS/SSL for client-server communication provides the following by default: When running the sample client programs, you can communicate with an existing server, such as a web server, or you can communicate with the sample server program, ClassFileServer. It’s definitely not recommended to mention the fingerprints statically in the code. How do digital function generators generate precise frequencies? The certificates will then allow the hacker to intercept encrypted communication which is well-known as a man-in-the-middle attack. To set up one-way SSL between Strong Authentication Server and User Data Service (UDS), the UDS Server requires certificates.
