SHA-1 Luau

A pure Luau implementation of the SHA-1 hashing algorithm. Blazing fast (for Luau) and well-tested.

!! Warning: Cryptographically Broken !!

The SHA-1 hash function MUST NOT be utilized for crytographic purposes. It is vulnerable to collision attacks. For more information, see this website.

API

This module returns a single function with the following type signature:

sha1(message: string): (string, {number})

The message passed to this function will be hashed using the hashing algorithm. The hash is returned in two forms:

  1. As a sequence of 40 hexadecimal digits
  2. A read-only array of five 32-bit words that represent the hash
