-- sha2.lua
--------------------------------------------------------------------------------------------------------------------------
-- VERSION: 12 (2022-02-23)
-- AUTHOR: Egor Skriptunoff
-- LICENSE: MIT (the same license as Lua itself)
-- URL: https://github.com/Egor-Skriptunoff/pure_lua_SHA
--
-- DESCRIPTION:
-- This module contains functions to calculate SHA digest:
-- MD5, SHA-1,
-- SHA-224, SHA-256, SHA-512/224, SHA-512/256, SHA-384, SHA-512,
-- SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, SHAKE256,
-- HMAC,
-- BLAKE2b, BLAKE2s, BLAKE2bp, BLAKE2sp, BLAKE2Xb, BLAKE2Xs,
-- BLAKE3, BLAKE3_KDF
-- Written in pure Lua.
-- Compatible with:
-- Lua 5.1, Lua 5.2, Lua 5.3, Lua 5.4, Fengari, LuaJIT 2.0/2.1 (any CPU endianness).
-- Main feature of this module: it was heavily optimized for speed.
-- For every Lua version the module contains particular implementation branch to get benefits from version-specific features.
-- - branch for Lua 5.1 (emulating bitwise operators using look-up table)
-- - branch for Lua 5.2 (using bit32/bit library), suitable for both Lua 5.2 with native "bit32" and Lua 5.1 with external library "bit"
-- - branch for Lua 5.3/5.4 (using native 64-bit bitwise operators)
-- - branch for Lua 5.3/5.4 (using native 32-bit bitwise operators) for Lua built with LUA_INT_TYPE=LUA_INT_INT
-- - branch for LuaJIT without FFI library (useful in a sandboxed environment)
-- - branch for LuaJIT x86 without FFI library (LuaJIT x86 has oddity because of lack of CPU registers)
-- - branch for LuaJIT 2.0 with FFI library (bit.* functions work only with Lua numbers)
-- - branch for LuaJIT 2.1 with FFI library (bit.* functions can work with "int64_t" arguments)
--
--
-- USAGE:
-- Input data should be provided as a binary string: either as a whole string or as a sequence of substrings (chunk-by-chunk loading, total length < 9*10^15 bytes).
-- Result (SHA digest) is returned in hexadecimal representation as a string of lowercase hex digits.
-- Simplest usage example:
-- local sha = require("sha2")
-- local your_hash = sha.sha256("your string")
-- See file "sha2_test.lua" for more examples.
--
--
-- CHANGELOG:
-- version date description
-- ------- ---------- -----------
-- 12 2022-02-23 Now works in Luau (but NOT optimized for speed)
-- 11 2022-01-09 BLAKE3 added
-- 10 2022-01-02 BLAKE2 functions added
-- 9 2020-05-10 Now works in OpenWrt's Lua (dialect of Lua 5.1 with "double" + "invisible int32")
-- 8 2019-09-03 SHA-3 functions added
-- 7 2019-03-17 Added functions to convert to/from base64
-- 6 2018-11-12 HMAC added
-- 5 2018-11-10 SHA-1 added
-- 4 2018-11-03 MD5 added
-- 3 2018-11-02 Bug fixed: incorrect hashing of long (2 GByte) data streams on Lua 5.3/5.4 built with "int32" integers
-- 2 2018-10-07 Decreased module loading time in Lua 5.1 implementation branch (thanks to Peter Melnichenko for giving a hint)
-- 1 2018-10-06 First release (only SHA-2 functions)

-- Q:
-- SHA2 was designed for FPU-less machines.
-- So, why floating point numbers are needed for this module?
-- A:
-- 53-bit "double" numbers are useful to calculate "magic numbers" used in SHA.
-- I prefer to write 50 LOC "magic numbers calculator" instead of storing more than 200 constants explicitly in this source file.

-- Q:
-- Does it mean that almost all non-standard configurations are not supported?
-- A:
-- Yes. Sorry, too many problems to support all possible Lua numbers configurations.
-- Lua 5.1/5.2 with "int32" will not work.
-- Lua 5.1/5.2 with "int64" will not work.
-- Lua 5.1/5.2 with "int128" will not work.
-- Lua 5.1/5.2 with "float" will not work.
-- Lua 5.1/5.2 with "double" is OK. (default config for Lua 5.1, Lua 5.2, LuaJIT)
-- Lua 5.3/5.4 with "int32" + "float" will not work.
-- Lua 5.3/5.4 with "int64" + "float" will not work.
-- Lua 5.3/5.4 with "int128" + "float" will not work.
-- Lua 5.3/5.4 with "int32" + "double" is OK. (config used by Fengari)
-- Lua 5.3/5.4 with "int64" + "double" is OK. (default config for Lua 5.3, Lua 5.4)
-- Lua 5.3/5.4 with "int128" + "double" will not work.
-- Using floating point numbers better than "double" instead of "double" is OK (non-IEEE-754 floating point implementation are allowed).
-- Using "int128" instead of "int64" is not OK: "int128" would require different branch of implementation for optimized SHA512.
-- Check for LuaJIT and 32-bit bitwise libraries
