shorthash

• A mini Node.js module to generate short, alpha-number, undecryptable and unique hash id from a long string (utf8 format).
• Use shorthash when you want to encrypt a string like a movie name or a people name to a short, unique and url friendly id.
• so with shorthash, you can build an id-string map, instead of quering the id from db each time, you just calculate the id out on the fly.
• it's quite convenient in many conditions if you want to build a site like 书本画, a book search engine in China.
• set hash dictionary - the list of characters allowed in the hash
