qrpff is a Perl script created by Keith Winstein and Marc Horowitz of the MIT SIPB. It performs DeCSS in six or seven lines. The name itself is an encoding of "decss" in rot-13. The algorithm was rewritten 77 times to condense it down to six lines.
In fact, two versions of qrpff exist: a short version (6 lines) and a fast version (7 lines). Both appear below.
