A free implementation of the DVB Common Scrambling Algorithm with encryption and decryption capabilities.

  • 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.
