I am thrilled to announce that the first base85x code is available online on SourceForge for free! During the last couple of weeks I tried differen approaches to implement base85x in java with a good performance.
The project as well as the source code is available here: https://sourceforge.net/projects/base85xjava/. Downloads will be packed as soon as there are more tests and better comments in the code.
Next step will be a simple but less efficient PHP implementation in order to be able to provider an online encoder and decoder for base85x.
