Each generator yields 128-bit security passwords. Each generator can take an optional numeric password to generate that many passwords. They should be placed in your ~/.zshrc. They are not portable across other shells.

gen-monkey-pass generates visually unambiguous random meaningless strings using Crockford's base32. Requires only ZSH:

% gen-monkey-pass

% gen-monkey-pass 3

Convert any binary to PNG

This walk through comes from @GalacticFurball who tweeted two images representing the youtube_dl source code as of 2020-09-20. They mentioned later in the thread that they struggled converting the gzip-compressed tarball of the source code with Imagemagick to a PNG, so they ended up using a 3rd party website to do the work. This Gist will show you how to do it cleanly and exactly.

Instructions

If you would like to convert any non-image binary into PNG, Imagemagick makes this trivial. I will be executing the commands on a Debian Linux system, so you may need to adjust the commands for BSD, macOS, or Windows as necessary.

Creating a BIP39 mnemonic 100% by hand (almost)

This document shows how we can create Bitcoin wallet mnemonic seeds by hand in a provably secure way. It follows the BIP-39 specification. The steps are straight forward, and we'll go into each of them in detail with this doc.

The steps are as follows:

Generate cryptographically secure bits
Divide into 11-bit bytes

World AreoPress Championship Winning Recipes

Comments

Just a basic table. See the full instructions at the WAC winners page.

World AeroPress Competition recipes are typically concentrate-then-dilute. This leads to higher losses of brewed coffee in the discarded puck. The coffee is generally coarser and brewed at lower temperatures to produce high acidity, but it also brews underextracted. Higher quantities of coffee are used (30+ grams)

Alternate EFF long list in Deseret and Shavian alphabet characters

An Idea for Passphrases

Knowing the growing support for Unicode support on the web, including HTML forms, such as usernames and passwords, I decided to create two English spelling reform Diceware word lists in the Deseret Alphabet and the Shavian Alphabet.

	#!/usr/bin/env python

	def _rot90(num):
	counter = 0
	bits = "{:09b}".format(num)
	tmp = list(bits)

	for idx in [6,3,0,7,4,1,8,5,2]:
	tmp[idx] = bits[counter]
	counter += 1

	$ for i in {1..50}; do printf "%02d: " $i; dbus-uuidgen; done
