Tested on OS X 10.6.8 with GCC 4.2.1 and 10.9.1 with Apple LLVM 5.0.

src/ is the current (as of July 13th, 2014) result of make fetch (cvs get) and make hash-helpers (sed).

If you don't trust me (or github) to not have modified anything in there to insert a backdoor (why should you?), but you trust the upstream OpenBSD version, then simply rm -r src it and audit the rest of the files that constitute this "port". It's less than 200 lines, you can do it :)

I've included a copy of the upstream signify source in this repo for convenience, but you should probably fetch it yourself. Doing so requires a working cvs, which does not come with new OS X systems by default, so either install that first (with macports or homebrew or whatever), or just use the src shipped in this repo (as I know it works).

To get the latest upstream source:

rm -r src
make fetch

and then the usual make, make install.

To run the regression tests, make test.

To check for upstream updates, make check-updates. (requires working CVS)
