I am pleased to report that people have been jumping on the decompiled Java-based VP5 decoder. Notably, it was clear to one individual that the method called clinch() that read bits from the stream using some bizarre algorithm is, in fact, an arithmetic decoding algorithm.

Regarding credits: I realize that many people engaged in reverse engineering activities are a little paranoid about having their achievements recognized. As such, my default policy is to not mention a contributor’s name unless they specifically ask for credit.

This is the current version of the decompiled VP5 Java cryptogram. Updates may occur at any time so check on the version number and timestamp inserted by SVN.
