PKA (Public Key Association) was a DNS based key discovery method
which looked up fingerprint by mail addresses in the DNS.  This goes
back to the conference where DKIM was suggested to show that we
already had a better method for this available with PGP/MIME.  PKA was
was later superseded by an experimental DANE method and is today not
anymore relevant.  It is anyway doubtful whether PKA was ever widely
used.
