What is libopenid4java-java
libopenid4java-java is:
OpenID starts with the concept that anyone can identify themselves on the Internet the same way websites do - with a URI. Since URIs are at the very core of Web architecture, they provide a solid foundation for user-centric identity. The first piece of the OpenID framework is authentication – how you prove ownership of a URI. Today, websites require usernames and passwords to login, which means that many people use the same password everywhere. With OpenID Authentication, your username is your URI, and your password (or other credentials) stays safely stored on your OpenID Provider (which you can run yourself, or use a third-party identity provider).
The library provided by this package supports the following specifications:
- OpenID Authentication 2.0
- OpenID Authentication 1.1 (in compatibility mode)
- OpenID Attribute Exchange 1.0
- OpenID Simple Registration 1.0 and 1.1, draft 1
- OpenID Provider Authentication Policy Extension 1.0
- OpenID Information Cards 1.0, draft 1
