Quick Start - contains a simple, complete example of an HTTP GET and POST with parameters. HttpClient Tutorial; HttpClient Examples - a set of examples demonstrating some of the more complex use scenarios. HttpClient Primer - explains the scope of HttpClient. Note that HttpClient is not a browser. The following tutorial demonstrates how to obtain the certificates from the resource server using Apache HttpClient 4.5. Certificates are used to secure the connection between the client and server over HTTPS using SSL/TLS. Using Secure Socket Layer, you can establish a secured connection between the client and server. It helps to safeguard sensitive information such as credit card numbers, usernames, passwords, pins, etc. You can make connections more secure by creating your own SSL context using the HttpClient library.
Apache HttpComponents Client. Welcome to the HttpClient component of the Apache HttpComponents project. Building Instructions. For building from source instructions please refer to BUILDING.txt. HttpClient main module requires Java 7 compatible runtime and depends on the following external libraries: Apache HttpComponents HttpCore. SSLConnectionSocketFactory (Apache HttpClient 4.5.12 API), TLS is a cryptographic protocol that provides end-to-end security of data sent between applications over the Internet. It is mostly familiar to users through its use in secure web browsing, and in particular the padlock icon that appears in web browsers when a secure session is established.
When working on a client that works with an SSL enabled server running in https protocol, you could get error 'unable to find valid certification path to requested target' if the server certificate is not issued by certification authority, but a self signed or issued by a private CMS.
Don't panic. All you need to do is to add the server certificate to your trusted Java key store if your client is written in Java. You might be wondering how as if you can not access the machine where the server is installed. There is a simple program can help you. Please download the Java program and run
This program opened a connection to the specified host and started an SSL handshake. It printed the exception stack trace of the error that occured and shows you the certificates used by the server. Now it prompts you add the certificate to your trusted KeyStore.

If you've changed your mind, enter 'q'. If you really want to add the certificate, enter '1', or other numbers to add other certificates, even a CA certificate, but you usually don't want to do that. Once you have made your choice, the program will display the complete certificate and then added it to a Java KeyStore named 'jssecacerts' in the current directory.
To use it in your program, either configure JSSE to use it as its trust store or copy it into your $JAVA_HOME/jre/lib/security directory. If you want all Java applications to recognize the certificate as trusted and not just JSSE, you could also overwrite the cacerts file in that directory.
After all that, JSSE will be able to complete a handshake with the host, which you can verify by running the program again.
