Generates secure passwords with at least 72 bits symmetric security using patterns on the keyboard from different English layouts.
"use strict";
const COLEMAK = {
// top row
"`": ["1", "!"], get "~"() { return this["`"]; },
"1": ["`", "~", "2", "@", "q", "Q"], get "!"() { return this["1"]; },
"2": ["1", "!", "3", "#", "w", "W"], get "@"() { return this["2"]; },
"3": ["2", "@", "4", "$", "f", "F"], get "#"() { return this["3"]; },
"4": ["3", "#", "5", "%", "p", "P"], get "$"() { return this["4"]; },
"5": ["4", "$", "6", "^", "g", "G"], get "%"() { return this["5"]; },
