I Done Left Los Windows…

Wednesday, January 30th, 2008

I’m blogging about my personal computing environment over on my “personal” blog, and just posted a note about my recent migration from MS Windows XP to (K)ubuntu GNU/Linux. Here’s a pointer to it..

This page..

SAML Open Source Implemenations

PHP SAML 2.0 IdP launched!

Friday, September 7th, 2007

Andreas Åkre Solberg writes on his Feide blog..

simpleSAMLphp 0.3 is launched. Most interesting in this new release is the SAML 2.0 IdP functionality. The documentation is not covering everything in detail yet, but it should be sufficient to get something up running.

The simpleSAMLphp 0.3 package also features a Shibboleth 1.3-compatible SP written in PHP.

XMLdsig implementations for scripting languages

Wednesday, December 20th, 2006

Various folks in what is becoming known as the “scripter” community, i.e. people who code in Perl/PHP/Python/Ruby scripting languages, have complained that SAML is “too hard” to implement, for essentially two reasons..

The first excuse is becoming more and more moot as tools and techniques proliferate and experience grows.

The second is, it appears, becoming more mitigated with the appearance of various packages that implement XMLdsig for the scripting world. Here’s pointers to a couple…

Rob Richard’s XMLseclibs for PHP

XMLsig for Dynamic Languages (Ruby, Python, PHP and Perl)

Now, I hear that some in the scripter community perhaps won’t like the XMLsig package because it is scripting languages wrapped around C wrapped around the xmlsec library (, rather than a “native” scripting-language implementation, which is what Rob Richard’s apparently is. Well, time will tell, and in any case, it is good to see this base beginning to get covered.

John Kemp points out that he wrote up a brief HowTo paper on writing essentially a library similar to XMLsig-for-Dynamic-Langs, for PHP, back in April 2006. Since Aleksey Sanin has already done the work of implementing XMLdsig, it seems to me to make sense to take advantage of it. Here’s JohnK’s material…
