[Adding bug-gnulib to CC. This discussion no longer directly affects Emacs, since I removed the libcrypto support from Emacs yesterday <http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/115454>. Gnulib still has support for linking to libcrypto, though, so it's still relevant for gnulib. This email thread starts at <http://lists.gnu.org/archive/html/emacs-devel/2013-12/msg00252.html>.]

Did you mean that Linux is the "Major Component" as described in the GPL? If so, that doesn't sound right, as the code we're talking about is crypto hash code, which doesn't need to interface to the Linux kernel at all. It's written in pure C and/or assembly code, with no Linux system calls. The Major Component here is not the Linux kernel; it's cryptographic services, which these days are a major essential component of many operating systems, including common GNU/Linux distributions. Obviously one can build a GNU/Linux system without crypto, just as one can build one without a windowing system, but nevertheless crypto is a major essential component for many systems, just as windowing is. > I don't think it satisfies (b) either. I don't see why not, for the crypto hash functions we're talking about. MD5, SHA256, etc. are all interfaces that are official standards defined by recognized standards bodies, and implementations for them are available to the public in source code form.
