Description

I've detected someone bruteforce my HiddenServiceAuthrozeClient key
and using it to access my HiddenService.
Client computers are NOT compromised.

HidServAuth can be compromise by brute force, because it's length is
just 16.
Please make it extremely longer, for example, 4096bit.
Or add ".crt/.pem" authorization method.

Prop. 224 "Next-Generation Hidden Services in Tor" has Ed25519 signature based client authentication (3.4.2) during the Intro phase that meets these requirements, and would be the logical place/timeframe to improve the current situation.

We've merged HSv3 client authentication, so this ticket can close.
