This project contains a set of useful Java general utility classes. The classes focus on the following areas:

• number base conversions (bases 2, 16, 32, and 64)
• primitive type to byte array conversions
• cryptographically secure random number generation for specific purposes
• a natural object comparator that works on anything
• a universal random hash function

The following highlights the utility classes provided by this project:

• Base02Utils - converts between byte arrays and base 2 strings
• Base16Utils - converts between byte arrays and base 16 strings
• Base32Utils - converts between byte arrays and base 32 strings
• Base64Utils - converts between byte arrays and base 64 strings
• ByteUtils - converts between byte arrays and primitive types
• RandomUtils - generates random array indexes, probabilities, and byte arrays
• NaturalComparator - compares any two objects of the same type
• UniversalHashFunction - generates a provably random distribution of hash values
