6 bytes does not provide a sufficient security margin for key
verification. This is still well within the realm of a brute force

PGP key IDs are not intended for the purposes of securely
authenticating keys. They are intended for a more Git-like purpose:
telling a small set of local keys apart.

You should still provide a secure digest for authenticating public keys.
