libdvbcsa is a free implementation of the DVB Common
Scrambling Algorithm - DVB/CSA - with encryption and
decryption capabilities.
Features
   * Portability. This library has been successfully
     tested on different processors with 32 bits,
     64 bits and 128 bits word width, little-endian
     and big-endian bytes ordering.
   * Performance. It comes in two flavors: a classical
     single packet implementation and a faster parallel
     bitslice implementation.
   * The parallel implementation can take advantages
     of MMX, SSE or Altivec instruction sets. Parallel
     implementation can process Mpeg TS packets at
     300Mbps or more on recent processors.
   * Freedom. libdvbcsa is released under the General
     Public License, ensuring it will stay free, and used
     only for free software products.
   * Simplicity. The API comes with only 5 functions
     fot the single packet implementation, and 6 functions
     for the parallel bitslice implementation.
