Not sure which one is in the Ubuntu repository. Although John the Ripper is Solar Designer's baby, most of the current development (under Solar's guidance) occurs in the "jumbo" version led by another developer named magnum. You can download that version here: https://github.com/magnumripper/JohnTheRipper https://github.com/magnumripper/JohnTheRipper Then you can build it with CUDA or OpenCL, SSE, OpenMP, MPI, etc., support using the Makefile.
