Java Secure Socket Extension
Java Secure Socket Extension ( JSSE ) is a Java - programming interface (API) for Transport Layer Security (TLS / SSL). It is a standard component of the Java Standard Edition from version 1.4, which provides the functionalities that are required for secure communication. With older Java versions, additional JSSE libraries can be included in the class path. JSSE supports SSL 3.0 and TLS 1.2. It is used for encryption , client and server authentication and data integrity . Due to its pure Java implementation, it can be easily integrated into your own Java programs. In addition to the implementation of the API algorithms, the JSSE also contains tools (e.g. for creating a keystore).
