yassl<\/a> is said to be Yet Another SSL library and I’ve been told that for example it is the preferred library used by the mysql<\/a> camp. I got interested in this several years ago when I learned about it since I thought it was fun to see an alternative implementation of OpenSSL that still offers the same API.<\/p>\n

Since then, I’ve amused myself by trying to build and run curl<\/a> with it like every six months or so. I’ve made (lib)curl build fine with yassl (and its configure script also detects that it is an OpenSSL API emulated by yassl), but I’ve never<\/strong> seen it run the entire curl test suite through without failing at least one test!<\/p>\n

I asked the mysql guy about how yassl has worked for them, but he kind of shrugged and admitted that they hadn’t tried it much (and then I don’t know really who he spoke for, the entire team or just he and his closest friends) but he said it worked for them.<\/p>\n

Today I noticed the yassl version 1.9.6 that I downloaded, built and tried against curl. This time curl completely fails to build with it…<\/p>\n

Let me also point out that it’s not like I’ve not told the yassl team (person?) about these problems in the past. I have, and there have been adjustments that have been meant to address problems I’ve seen. I just can’t make curl use it successfully… libcurl can still be built and run with OpenSSL, GnuTLS or NSS so it’s not like we lack SSL library alternatives.<\/p>\n

The same team\/person seems to behind another SSL lib called Cyassl that’s aimed for smaller footprint systems and I’ve heard whispers about people trying to get libcurl to build against that and it surely is going to be interesting to see where that leads!<\/p>\n
