Hello crypto-people,

Frank Denis just announced Sodium, a fork of NaCl containing only the
reference C code, packaged using a standard autotools build system:

NaCl has traditionally been hard to use because it targets *IX exclusively
and the assembly versions of the various algorithms are not PIC yet. For
this reason there are a lot of issues making NaCl work portably (e.g.
across 32-bit/64-bit platforms, let alone Windows)

Sodium is designed to be portable, easy to compile/package, and it even
works on Windows!

Some might think this undermines some of the original goals of NaCl,
however djb has suggested it as an option in the past:
