gnupg: Dirmngr VALIDATE

 
 3.6.6 Validate a certificate for debugging
 ------------------------------------------
 
 Validate a certificate using the certificate validation function used
 internally by dirmngr.  This command is only useful for debugging.  To
 get the actual certificate, this command immediately inquires it using
 
        S: INQUIRE TARGETCERT
        C: D <DER encoded certificate>
        C: END
 
    Thus the caller is expected to return the certificate for the request
 as a binary blob.
