Thanks for that! I just fixed that and now the error I get the second time
I upload is the "NO_DATA" error (which is reasonable as it decrypts anyways
with no data), Again the file that is obtained through the upload can still
be decrypted via the command line just fine.

Is there a reason why you use the asynchronous operaions and not the
synchronous?  Your code would not work with multiple threads because
gpgme_wait may only be called by one thread.


The only reason I have it as asynchronous would be because the file that is
being decrypted is then unzipped and its contents loaded elsewhere - but
rather than using a library (as of current), I just called a system() to
execute the zip and without this.

gpgme has a function to figure this out:

  /* Get the information about the configured engines.  A pointer to the
   * first engine in the statically allocated linked list is returned.
   * The returned data is valid until the next gpgme_ctx_set_engine_info.
*/
  gpgme_engine_info_t gpgme_ctx_get_engine_info (gpgme_ctx_t ctx);

With this I can confirm its using 2.0.22.
