krecaptchareCAPTCHA library in C

krecaptcha is a simple library for interfacing with the reCAPTCHA service, which these days is operated by Google. (If you don't know what CAPTCHA is, start here.) The ISO C source code is ISC licensed. To use krecaptcha, you'll need a modern UNIX system with libcurl installed. Compile with make and install with make install into the default PREFIX. Consult krecaptcha(3) for documentation. krecaptcha is a project.

This library is still quite new, so it will evolve to become more secure. For example, the whole invocation of libcurl should be in a separate child process. Contact Kristaps with questions or comments.
