Well if a MITM attacker tries to use your ssh access to do anything nasty, another developer will probably notice quite quickly. (the only nasty thing the ssh access allows you to do is hg push, IIRC; still, that can trigger code execution on the buildbots) Sure, but it would be better to

Can someone log into hg.python.org and get the public keys for the server? Not me. But from my hosts, I get: RSA key fingerprint is ec:98:fe:7b:e1:0f:88:c5:93:37:83:64:a4:cc:aa:01. Well I'm not sure how logging in would be an improvement, since the person logging in could also be the victim

Also, what is the command to use on the server to get the public key fingerprint? Run ssh-keygen -lf /path/to/public/key.pub for the RSA, DSA, and ECDSA keys. ___ python-committers mailing list python-committers@python.org

In addition, the email you sent might be subject to MITM, either when you were submitting it, or when it was transmitted from python.org to Roger's SMTP server. So you really need to PGP sign it :-) And hope that I have Antoine's correct public PGP key... And down the rabbit hole we go.

Hi All, What should be the ssh fingerprint be for hg.python.org? I am receiving 63:75:9b:14:b7:b2:dc:e7:cd:42:d7:19:48:6a:68:8e, but I can't verify if it's correct. Thank you, Roger ___ python-committers mailing list python-committers@python.org
