   Well, it seems it was a misundertanding. I thought you mean libcrypt
   indeed of libgcrypt. At version 1.4.0 of the 6 December 2007,
   libgcrypt supports both AES and ARC4 encryptation algorithms, and md5
   hashing function. :)

Nice then :) 

It seems that at least we should provide filters for AES and arc4. We
will get the parameters for the filters from both the filter
dictionaries and the encryption dictionary. Could you please write
down a summary of all the needed parameters for both filters?
