ZXID.org Identity Management toolkit implements standalone SAML 2.0
and Liberty ID-WSF 2.0 stacks. It is a C implementation with minimal
external dependencies - OpenSSL, CURL, and zlib - ensuring easy
deployment (no DLLhell). Due to its small footprint and efficient and
accurate schema driven implementation, it is suitable for embedded and
high volume applications. Language bindings to all popular highlevel
languages such as PHP, Perl, and Java, are provided via SWIG. ZXID
implements, as of July 07, SP, WSC, and WSP roles.
