Hi,
Since security minded people will be reading these posts, I wanted to mention I found an BSD licensed PGP library with Lua bindings, but don't have the focus to actually do anything with it. The library is called netpgp and is available here:
I was able to get the base library working and did some tests, but couldn't get the lua bindings to build (lack of make skills). I was able to verify a signed file, but couldn't get detached signatures to work and got a SIGSEV when mucking with the keyring library.
The author hasn't responded to an initial hello message so I'm not sure if it's maintained, but it would sure be nice to see this tool in LuaRocks if anyone is so inclined.
Thanks to Bruno and everyone keeping Lua communications secure.
Cheers,
Russ
