PedroAlvesV / sha2for51.lua
Created August 31, 2018 18:29
working implementation of SHA512 for Lua 5.1
-- This module contains functions to calculate SHA2 digest.
-- Supported hashes: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256
-- This is a pure-Lua module, compatible with Lua 5.1
-- It works on Lua 5.1/5.2/5.3/5.4/LuaJIT, but it doesn't use benefits of Lua versions 5.2+
-- Input data may must be provided either as a whole string or as a sequence of substrings (chunk-by-chunk).
-- Result (SHA2 digest) is a string of lowercase hex digits.
--
-- Simplest usage example:
-- local your_hash = require("sha2for51").sha512("your string")
