 8.5 Using cryptographic functions
 =================================
 
 The following flags might be relevant:
 
 `GCRY_AC_FLAG_NO_BLINDING'
      Disable any blinding, which might be supported by the chosen
      algorithm; blinding is the default.
 
  -- Function: gcry_error_t gcry_ac_data_encrypt (gcry_ac_handle_t
           HANDLE, unsigned int FLAGS, gcry_ac_key_t KEY, gcry_mpi_t
           DATA_PLAIN, gcry_ac_data_t **DATA_ENCRYPTED)
      Encrypts the plain text MPI value DATA_PLAIN with the key public
      KEY under the control of the flags FLAGS and stores the resulting
      data set into DATA_ENCRYPTED.
 
  -- Function: gcry_error_t gcry_ac_data_decrypt (gcry_ac_handle_t
           HANDLE, unsigned int FLAGS, gcry_ac_key_t KEY, gcry_mpi_t
           *DATA_PLAIN, gcry_ac_data_t DATA_ENCRYPTED)
      Decrypts the encrypted data contained in the data set
      DATA_ENCRYPTED with the secret key KEY under the control of the
      flags FLAGS and stores the resulting plain text MPI value in
      DATA_PLAIN.
 
  -- Function: gcry_error_t gcry_ac_data_sign (gcry_ac_handle_t HANDLE,
           gcry_ac_key_t KEY, gcry_mpi_t DATA, gcry_ac_data_t
           *DATA_SIGNATURE)
      Signs the data contained in DATA with the secret key KEY and
      stores the resulting signature in the data set DATA_SIGNATURE.
 
  -- Function: gcry_error_t gcry_ac_data_verify (gcry_ac_handle_t
           HANDLE, gcry_ac_key_t KEY, gcry_mpi_t DATA, gcry_ac_data_t
           DATA_SIGNATURE)
      Verifies that the signature contained in the data set
      DATA_SIGNATURE is indeed the result of signing the data contained
      in DATA with the secret key belonging to the public key KEY.
