Yes, but my patch uses `CDK_DBTYPE_PK_DATA' because the data comes from
a user-provided buffer, not from a file.  In this case,
`cdk_keydb_new ()' just creates a temporary stream from the user buffer,
without leaving the opportunity set/clear that stream's armor flag.

It would be best to at least have the ability to not rely on automatic
detection of the format, especially since callers pass a FORMAT
argument.

That would allow `gnutls_openpgp_keyring_import ()' to support both
base64 and raw in a straightforward way.

Are you considering implementing it in a future version?

Then what?  :-)

It seems that your message got somehow stripped.

Thanks,
Ludovic.
