This is a modest suggestion for the new 52 chars onion urls. If it is possible to encode the creation date of the onion private key in the public onion url, it would help a bit in allowing the users to detect if an onion url is the real deal or if it is a phishing url. Reasoning is the older url would most likely be the genuine url.

How would that be authenticated? That is, if I see an address that says it was created on August 1, how do I know that's true?

I'm putting this into 0.3.2.x since that's our last chance to change the .onion address format for a while, but I'm thinking we probably won't be able to get it to work on time unless there's an easy way to do it

I also don't see how encoding the creation date of the .onion key in the address will allow a user to distinguish a real address or a phishing one... ?

@dgoulet If you could please have a look at 7cbqhjnlkivmigxf.onion

It is an index of .onion addresses with the first seen date of each onion shown in parenthesis.

As an example, if you search for the onion crate, you'll see three similar looking links but differing first seen dates.

The onion crate - Tor hidden service index

7cbqhjnlkivmigxf.onion (2016-06-11) (Verified)
7cbqhjnpcgixggts.onion (2016-10-10) (Phishing link)
7cbqhjnlkikwzipx.onion (2017-08-11) (Phishing link)

I think the users would be better off if they can verify that 7cbqhjnlkivmigxf is indeed the oldest key of those 3 and therefore the original.

please see my questions above; I think this might not be as possible as you think it is. But if it _is_ possible, I want to know how. ;)
