OpenSAML is a powerful library that simplifies working with SAML (Security Assertion Markup Language) messages. It provides functionalities like creating, parsing, signing, encrypting, and transporting SAML objects as XML. Developed and supported by Internet2, OpenSAML is utilized in various identity solutions, including Shibboleth products. This guide provides resources and tutorials, with a focus on OpenSAML V3, to help you get started.
What is OpenSAML?
OpenSAML streamlines the process of interacting with SAML messages. Key functions include:
- Creating SAML messages: Constructing valid SAML requests and responses.
- Parsing and exporting SAML objects: Converting SAML data to and from XML.
- Signing and encryption: Securing SAML messages for confidentiality and integrity.
- Encoding and message transport: Handling message formatting and delivery.
Licensed under Apache 2.0, OpenSAML supports SAML versions 2.0, 1.1, and 1.0. It is available in both Java and C++, although feature parity may vary.
