SDTP is a project to implement various crytographic and steganographic schemes and systems that previously have just been of academic interest. While these are currently implemented as stand-alonge commandline programs, it is my intention to later make them interoperate and eventually have a single application that calls the functions of the programs developed now.

Please notice that SDTP is in a very early state of development. At the moment, only hcommit can be considered usable and most of it is still missing. If you intent to use hcommit, I therefore recommend to encrypt the files with GnuPG and disguise it with some trustable steganographic tool until SDTP is in a state where it can be used alone.
