history
Project history and usage
OpenSAML is a Shibboleth-family implementation library for the OASIS Security Assertion Markup Language. The Homebrew opensaml formula packages the native C++ line, including the samlsign command-line tool, for software that needs SAML message construction, parsing, signing, and validation primitives.
Project history
OpenSAML grew around the Shibboleth identity-federation project, where SAML is the core protocol vocabulary for browser single sign-on and attribute exchange. The OpenSAML 2 documentation describes the project as open-source C++ and Java libraries for developers working with SAML 1.0, 1.1, and 2.0.
The project deliberately distinguishes the library from a complete identity provider or service provider. The documentation warns that OpenSAML does not provide a full SAML IdP/SP and is meant for developers who already understand the SAML specifications.
For the C++ 3.x line, Shibboleth documents OpenSAML-C as a separate project but supported only as a dependency of the Shibboleth Service Provider. The build documentation places it in the native Shibboleth stack with dependencies such as log4shib, OpenSSL, libcurl, Xerces-C, XML-Security-C, and XMLTooling-C.
Adoption history
OpenSAML's adoption is strongest inside identity middleware rather than end-user CLI workflows. The historical OpenSAML page lists Shibboleth, Globus Toolkit components, grid identity projects, Apache WSS4J, Apache Rampart, eduGAIN, OpenLiberty Wakame, SuisseID SDK/Java, and other projects as users or integrators.
Distribution packaging follows that dependency role. openSUSE's Apache:Shibboleth package describes opensaml as a C++ implementation supporting SAML 1.0, 1.1, and 2.0, while Homebrew, Debian, Ubuntu, MacPorts, and zypper package it for native Shibboleth and SAML tooling stacks.
How it is used
Developers use OpenSAML-C as a library inside SAML-capable services rather than as an application framework. It supplies C++ classes and XML/security integration for SAML assertions, protocol messages, bindings, signatures, and related metadata operations.
Operators encounter the package as part of Shibboleth Service Provider builds and security maintenance. The C++ product version policy explains that native Shibboleth and OpenSAML components use MAJOR.MINOR.PATCH versioning and track compatibility across binary linkage, public APIs, configuration, and protocol behavior.
Why package nerds care
opensaml is a dependency-heavy security library package where ABI compatibility matters. Package maintainers care about coordinated versions of XMLTooling-C, XML-Security-C, Xerces-C, OpenSSL, log4shib, and Shibboleth SP, because C++ API changes can force recompilation and soname changes.
Timeline
- 2016-07-31: security maintenance ceased for the OpenSAML V2 Java release branch.
- 2018-07-17: security maintenance ceased for the OpenSAML V2 C++ release branch.
- 2021-08-17: Shibboleth's C++ product version policy page documented native/OpenSAML versioning and compatibility rules.
- 2021-11-24: the OpenSAML-C page for Shibboleth SP 3 was updated and documented C++ 3.x support as part of Shibboleth SP.
- 2025-03-13: the Shibboleth download index lists opensaml-3.3.1 source artifacts.
Related projects
- Related Shibboleth native components include XMLTooling-C, XML-Security-C, log4shib, and the Shibboleth Service Provider. Protocol-adjacent projects include Apache WSS4J, Apache Rampart, Globus Toolkit components, eduGAIN, and other SAML federation software.
