Why are you sure that these are "certificates of authorities"? It seems
that this is just a fingerprint of a relay that is not in consensus
anymore and thus relays don't have the cert for it to serve over either
DirPort or begindir. But your client still has it (somehow).

This it really old. I'm curious about what are reasons behind it.
Please don't run relays on that old versions.
