public class Hashids
extends Object

Hashids designed for Generating short hashes from numbers (like YouTube and Bitly), obfuscate database IDs, use them as forgotten password hashes, invitation codes, store shard numbers.

This is implementation of http://hashids.org v1.0.0 version.

This implementation is immutable, thread-safe, no lock is necessary.

从以下版本开始:

0.3.3
