BIAC is an adaptive bijective arithmetic compressor implemented in Java.

BIAC is an adaptive bijective arithmetic compressor implemented in Java.It is a direct port of David Scott`s 62-bit bijective arithmetic compressor - and is binary-compatible with it. The bijective property means that - as well as decompress(compress(f)) for any file f, compress(decompress(f)) for any file f. The bijective property results in a minimisation of added known PlainText when the compressor is used prior to encryption. There is a GUI front end as well as a command-line interface. Here`s a snapshot of it in action:
