Show HN: My SSH server knows who you are
Cripes, people.  WHO CARES?<p>So I SSHed in.  I got the message.  Then I saw all the people freaking out here and couldn't believe my eyes.<p>Ask yourself this:<p>How often do you SSH in to arbitrary hosts?  Ones that you don't control, or work for, or trust with your source code?<p>Did you really expect that you could give the same long unique base64 string to a bunch of different hosts and NOT have them connect your identity between them?<p>Do you not understand that the whole point of public keys is to uniquely and reliably identify yourself to an arbitrarily large number of parties?<p>Honestly, the only real eye-opener here is that Github gives out your public keys and can be scraped to collect all of them.  But some of us have been using that functionality to share / snag each other's public keys for a long time now anyway.
