On the Lua wiki
I saw an article: it is possible with Lua 5.2. Can I switch to Lua 5.2 and
still use Lua
modules/libs that are written for Lua 5.1? (luasocket, coxpcall, copas)
Any tips are welcome.
Indeed, Lua 5.2 has binary operators allowing to compute MD5 or similar
algorithms. Probably slower than a C version, but I suppose you won't check
thousands of password per second, so it should be OK.
AFAIK, most Lua libraries with native C code will need to be recompiled for
Lua 5.2. I had to do that for lfs, luasocket, lpeg...
If you don't mind using a C library with a binding for Lua,
you should try md5:
It can also be installed via LuaRocks:
