harveyrandall / XORCipher.js
Created October 29, 2025 11:05 — forked from sukima/XORCipher.js
A Super simple encryption cipher using XOR and Base64 in JavaScript
// XORCipher - Super simple encryption using XOR and Base64
//
// Depends on [Underscore](http://underscorejs.org/).
//
// As a warning, this is **not** a secure encryption algorythm. It uses a very
// simplistic keystore and will be easy to crack.
//
// The Base64 algorythm is a modification of the one used in phpjs.org

ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description Syntax
Get the length of a string ${#VARNAME}
Get a single character ${VARNAME[index]}

ZSH function to auto-switch to correct Node version
####
# ZSH function to auto-switch to correct Node version
# https://gist.github.com/callumlocke/30990e247e52ab6ac1aa98e5f0e5bbf5
#
# - Searches up your directory tree for the closest .nvmrc, just like `nvm use` does.
#
# - If you are already on the right Node version, IT DOES NOTHING, AND PRINTS NOTHING.
#
# - Works correctly if your .nvmrc file contains something relaxed/generic,
# like "4" or "v12.0" or "stable".
