Re: [pdf-devel] Crypt module

Hi David.

It seems that the filters never return PDF_EEOF when finish_p equals
to true: they return either PDF_ENINPUT or PDF_ERROR.

+          if (aux_size > out_size)
+            {
+              /* We should can return PDF_ENOUTPUT. However the
+                 output buffer is assumed to be full if we return
+                 PDF_ENOUTPUT, but we can not write it partially.  */
+              return PDF_ERROR;
+            }

The same problem that we found in the previous version: the filter
should cache the output of the cypher and write it step by step,
returning PDF_ENOUTPUT if the output buffer is not big enough to hold
all the data.

Did you send the right version of the filters?
