TortoiseHG and wildcard certificates

Having resolved recent SSL certificate issues with Mercurial/TortoiseHG, I now encountered a similar issue with the wildcard certificate for *.google.com where getting a clone would result in a "SSL: Server certificate verify failed" error.

One way around this issue is to add the fingerprint for this certificate to your configuration. Currently for *.google.com this is 00:d5:88:35:29:b9:7f:03:92:60:c2:04:e4:b7:01:f0:07:53:15:a8 and one way to get this from a Unix command line is with openssl s_client -connect code.google.com:443 < /dev/null 2> /dev/null | openssl x509 -in cert-code -fingerprint -noout -in /dev/stdin | tr "[:upper:]" "[:lower:]". This corresponds with Chrome’s certificate view’s thumbprint field, you just need to add colons.

Right click in Explorer, select TortoiseHG » Global Settings and then click Edit File and add the following:

[hostfingerprints]
code.google.com = 00:d5:88:35:29:b9:7f:03:92:60:c2:04:e4:b7:01:f0:07:53:15:a8

This should make Mercurial/TortoiseHG work, at least until the certificate expires and you need to update it with the latest fingerprint.
