+Searches a principal's key_data array to find a key with the specified
+enctype, salt type, and kvno, and decrypts the key into keyblock and
+keysalt if found.  entry must have been returned by
+kadm5_get_principal with at least the KADM5_KEY_DATA mask set.
+Returns ENOENT if the key cannot be found, EINVAL if the key_data
+array is empty (as it always is in an RPC client).
+
+If ktype or stype is -1, it is ignored for the search.  If kvno is -1,
+ktype and stype are ignored and the key with the max kvno is returned.
+If kvno is 0, only the key with the max kvno is returned and only if
+it matches the ktype and stype; otherwise, ENOENT is returned.
