  4. Generates HDCP keys (sink and source)
  5.  
  6. Based on the anonymous post of the HDCP master key
  7. posted here: http://pastebin.com/kqD56TmU
  8.  
  9. Relevant instructions included in post:
  10.  This is a forty times forty element matrix of fifty-six bit
  11.  hexadecimal numbers.
  12.  
  13.  To generate a source key, take a forty-bit number that (in
  14.  binary) consists of twenty ones and twenty zeroes; this is
  15.  the source KSV.  Add together those twenty rows of the matrix
  16.  that correspond to the ones in the KSV (with the lowest bit
  17.  in the KSV corresponding to the first row), taking all elements
  18.  modulo two to the power of fifty-six; this is the source
  19.  private key.
  20.    
  21.  To generate a sink key, do the same, but with the transposed
  22.  matrix.
