We have deployed SSLeay-based commercial banking applications using
Windows 32 sound card support for the RNG. It's based on a library
we call sndlib, which provides APIs for recording and playback
cross-platform, but which actually only implements Win32 recording.
I designed it that way with the thought of also building a cross-platform
web phone over SSL.
It provides a new SSLeay entry-point, RAND_sound(), which fills a buffer
of typically 8K with the LSBs of recorded samples at the highest bitrate
and two channels if available. You then pass the buffer to RAND_seed().
I've just asked permission to release the code (which already works with
SSLeay hence OpenSSL), and it's being considered. I'll keep you posted.
