OK, I fixed it in the CVS. The backport is pretty easy and just two

Actually this is a format for the structure, not the data itself.
Format: file, stream, buffer. Maybe I did not describe this very well :-(.

The idea was to auto detect base64 data and decode it. With the
new code, cdk_keydb_new_from_stream () no decoding is done.

OK, the stream version is also available in the CVS.
Just for clarification, I change/patch the code in HEAD, not the
nmvav-0-5-x branch GnuTLS currently uses.

As I said, it's done. Actually the new release 0.6.0, is not released
yet but the code is in the CVS. I will wait until the discussion is
done so I definitely know what to add/change in OpenCDK.

Sorry. It should be "if this is the only reason for the new code". IMHO
the issue is fixed with the armor support for CDK_DBTYPE_DATA and the
new cdk_keydb_new_from_stream() function.

As I said, the backport is pretty easy. But I would suggest to think of
a migration strategy because I fixed a lot of other stuff and GnuTLS
would definitely benefit of the new code.
