  Modified files:
    sys/conf             files 
  Added files:
    sys/geom             geom_aes.c 
  Log:
  Add a proof-of-concept encryption class.
  
  "The only hard problem in cryptography is key-management."
  
  All sectors are encrypted with AES in CBC mode using a constant key,
  currently compiled in and all zero.
  
  To activate this module, write the magic header on the partition:
  
          echo "<<FreeBSD-GEOM-AES>>" | dd conv=sync of=/dev/md98
  
  The encrypted device will be one sector shorter and have ".aes"
  appended to its name.
