Like skynet lua-crypt, But add md5、crc32、crc64、sha256、sha512、hmac_md5、hmac_sha256、hmac_sha512 supported.
Note that this is a Lua C API implementation, And tested by exmaple/testsha.lua file.
Copy all files in skynet-lua-crypt/src to the luaclib-src folder and replace the relevant files.
You can achieve fast compilation by simply replacing the skynet-lua-crypt/Makefile file with the skynet/Makefile file.
Finally, You need use make platform(linux/macosx/freebsd) to build it.
