[PATCH] OpenSSL CRL Support

Hi, I already asked for comments on inclusion of OpenSSL CRL support in ext/openssl some time ago (I had a independend extension at this point). As I continued working on it I realized that making this an independend extension makes me to reinvent/reimplement the wheel and makes it impossible to have ext/openssl and the CRL support to integrate nicely, so I wrote a patch to include it in ext/openssl. In fact, having Marc Delling's PKCS#12 patch and mine applied makes it possible to write basic but real PKI-CA applications in PHP, so I think it would be nice to have this. I know that there are not that many people who need this but I think this is true for nearly the whole openssl extension except for the stream wrapper. (maybe we should consider splitting it up?) You find a patch (hopefully I got your conding standards right ;)) attached, but I should take careful review because this actually is my first work on PHP extensions and I'm also not used to writing C code. I can/will provide a test (what kind of tests should I supply?) and documentation when needed. Moritz Bechler
