Actually that's not true, maybe the code does not work in the used
CDK release, but the keydb code has the ability to automatically
decode base64 files which are used as

As Simon pointed out, I re-wrote lots of the opencdk code and I
added a lot of tests to make sure all changes really work as expected.
I also write a test to use a base64 file as a keyring and I succeeded
to search for a key by keyid or by pattern.

As I said before, this is usually not needed. The both format which
are possible: raw, base64 should be supported.
If the opencdk version gnutls currently uses, does not support to
push the de-armor filter automatically, I guess it's the best idea to
fix it in keydb.c.

This might be a useful function and I will consider it.

..if the only reason for the new code is that base64 data is not supported,
