    Release Notes: This release adds memory locking and TTY echo suppression. A buffer overflow condition has been fixed.

      Release Notes: The security level now can be chosen freely in the range from 8 to 1024 bits in steps of 8. This makes the program's usage much simpler. The man page now contains a hint on how to share large files using ssss in hybrid mode (together with a block cipher).

          Release Notes: A special diffusion layer was added. It prevents cheaters from modifying the result of a share recombination in the way they want. This feature is essential for the very paranoid only.

            Windows port of ssss
            Just to let you know that I did a quick port of ssss to windows with MINGW. I had to replace the entropy source by RandomKit, because I couldn't get /dev/random to work.

            You can find the files and modified source at:

            I also compiled ssss on OpenBSD 3.5 from source with no problem.

            Thanks for the excellent utility --
