! Without zlib, the PGP functions will not support compressed data inside
! PGP encrypted packets.
  
! Without OpenSSL, public-key encryption does not work, as pgcrypto does
! not yet contain math functions for large integers.
  
! There are some other differences with and without OpenSSL:

  `configure` script.  The options that affect it are `--with-zlib` and
  `--with-openssl`.
  
! When compiled with zlib, PGP encryption functions are able to
! compress data before encrypting.
  
! When compiled with OpenSSL there will be more algorithms available.
! Also public-key encryption functions will be faster as OpenSSL
! has more optimized BIGNUM functions.

  Options are named to be similar to GnuPG.  Values should be given after
  an equal sign; separate options from each other with commas.  Example:
  
!   pgp_sym_encrypt(data, psw, 'compress-also=1, cipher-algo=aes256')
  
  All of the options except `convert-crlf` apply only to encrypt
  functions.  Decrypt functions get the parameters from PGP data.

  Those functions only run a cipher over data, they don't have any advanced

  1. They use user key directly as cipher key.
  2. They don't provide any integrity checking, to see
