public class Rot5

extends ReaderTransformer

implements CharTransformer

Rot5 implementation. Digits 0-4 are shifted 5 positions forward, digits 5-9 are shifted 5 backwards and other characters are untouched, which results in scrambled - but easily decoded - strings. You would want this to combine with Rot13 for the letters.
