Generate WP Salt Strings

generate-salts.js

/**
 * Simple Javascript that generates WordPress salts
 *
 * Note that the Javascript version affects uniqueness for some functions - for
 * example, `Math.random().toString(36).substring(7);` generates a lot of
 * duplicates when using old versions of Node, but over 1M iterations shows
 * no duplication in Node v6.2.2. We're not using this method anyway, so this
 * note is for academic interest only.
