HumanHash provides human-readable representations of digests.
This is a port of duggan's ruby HumanHash implementation. Which is in turn a port of Jacon Carlson's ruby project which was originally based on Zachary Voase's Python implementation. So I can hardly take credit for this library as the work all belongs to those other great people and this is simply a port to the Crystal language.
icr(0.27.0)> require "./humanhash" icr(0.27.0)> digest = "535061bddb0549f691c8b9c012a55ee2" icr(0.27.0)> HumanHash.humanize(digest) => "alpha-twenty-mockingbird-twelve" icr(0.27.0)> icr(0.27.0)> h = HumanHash.uuid icr(0.27.0)> h.human => "berlin-avocado-may-nebraska" icr(0.27.0)> h.uuid => "f9c25578-55b8-46a8-bed5-40994056d10e" icr(0.27.0)> h.digest => "6ffb57d425e64d3993b381104e7bdb99"
Add this to your application's shard.yml:
dependencies: humanhash: github: kingsleyh/humanhash
Don't store the humanhash output, as its statistical uniqueness is only
256^words. Its intended use is as a human-readable (and, most
importantly, memorable) representation of a longer digest, unique enough
for display in a user interface, where a user may need to remember or verbally
communicate the identity of a hash, without having to remember a 40-character
hexadecimal sequence. Nevertheless, you should keep original digests around,
then pass them through
humanize() only as you're displaying them.
How It Works
The procedure for generating a humanhash involves compressing the input to a fixed length (default: 4 bytes), then mapping each of these bytes to a word in a pre-defined wordlist (a default wordlist is supplied with the library). This algorithm is consistent, so the same input, given the same wordlist, will always give the same output. You can also use your own wordlist, and specify a different number of words for output.
