12 * The routines in this file are meant to be used as an initial step when
13 * adding a new db access module. They provide various functions required
14 * of the db access module using only the store and fetch functions. As
15 * they need to parse the actual OpenPGP data to work they are a lot
16 * slower than custom functions however.

31 * keyid2uid - Takes a keyid and returns the primary UID for it.
32 * @keyid: The keyid to lookup.

128 * full keyid. If the key isn't found a keyid of 0 is returned.
