Pink Hash

It's like a pink elephant, but a hash

Convert hashes to mnemonic phrases.

Hashes are great for many machine-specific purposes, but if you give a hash to a person (e.g., display it on a console), you're doing something wrong. Humans struggle with remembering, comparing, or typing hashes accurately. For most people, 8f776debaf8b5031643aa463ba5bf0dc and 8f776debaf8b5013643aa463ba5bf0dc look essentially the same.

However, humans aren’t entirely useless — they can remember vivid phrases quite well. If you tell someone not to think about a pink elephant (or a white monkey), and then Margot Robbie calls to ask them out on a date, even after spending the entire evening and night with her, they’ll still be thinking about the pink elephant.

If a hash is converted into words, people will remember it much better:

• alter print drive // bip39 with en option by default, but we have fr, es, pt, it, ko, cz, zh-hant and zh-hans as well
• WELL LANE HELD // rfc1751
• configurational candidate // eng1
• Uniform X-ray November // nato

Installation

recommended way (you may want to apt install pipx for this):

pipx install pinkhash

or older way:

pip install pinkhash

CLI Usage

# get pink hash for stdin, default mode with bip39/en
$ echo "Hello world!" | pink 
hybrid interest chimney

# or in French...
$ echo "Hello world!" | pink  -o fr
gazelle griffure caméra

# Nato alphabet, 5 words
$ echo "Hello world!" | pink  -l nato -w 5

# eng1 always returns 2 words, no matter how many we ask
$ echo "Hello world!" | pink  -l eng1 -w 42

How to get pinkhash for files:

# pink can hash many files
$ pink *txt
cookies.txt: pelican number item
DNS.txt: shadow expire inhale
log.txt: absurd now caution

Python usage

Get pinkhash for a str with all default settings (Bip39 language as default).

from pinkhash import PinkHash
pink = PinkHash()
print(pink.convert('Hello world!'))

from pinkhash import PinkHash
import sys

pink = PinkHash(language_name='nato', nwords=3)
data = sys.stdin.buffer.read()
r = pink.convert(data)
print(r)

Languages

Each method to convert hash into words in Pinkhash is called an language. For example, nato is one language and rfc1751 is another language. Do not confuse this with a national language. Pinkhash now has built-in eng1 language (which produces adjective+noun pair from large set of english words) but in future there could be another english language, e.g. one which uses only simple popular words, or one which builds longer phrases or one which produces poems or haiku.

Usually (but not always) language can produce hashes of specified (-w) number of words, but eng1 never produces more then 2 words. Also pinkhash will not produce more words then needed to cover only lower 64bits of sha1 hash of input.

BIP-39 language (based on BIP-0039) has 10 options (wordlists), choose it with -o. See all options with -h/--help.

Disclaimer

While pinkhash uses RFC1751 and BIP-0039, it's not strictly following it! Pinkhash has it's own algorithms and just uses wordlists from these standards. Do not use pinkhash where you need strict standard compliance.

Mnemonical pink hashes are NOT cryptographically strong.
