   A crypt filter dictionary contains (amongst others) a key named CFM,
   whose value could be one of three:
      - None
      - V2 (for RC4/ARC4)
      - AESV2 (for AES)

So in the end we would need to write stm filters for RC4/ARC4 and AES,
isnt it? 

   Finally in filter dictionarity we found a key `name' which let us
   declare what crypt filter we want use. It is the name of a crypt
   filter defined in CF.

I dont fully understand. What is the difference between a "crypt
filter dictionary" and a "filter dictionary"?
