security - Is https traffic over an unencrypted wireless network secure?

This is something I've wondered for a long time. If I am, say, using Gmail over https, can someone read my IM conversations and emails if I use an unsecured wireless network? I assume that the data would be secure, since it is using an encrypted connection. Is there anything else to consider?

Answer

I would think that someone could still perform a man-in-the-middle attack if you're on unsecured wifi (or even secured wifi, if they happen to find a way to be allowed on). This is why you need to always check that the SSL connection shows up green in your address bar and/or manually double-check that the certificate is valid when using unsecured wifi. Assuming that the certificate is correct, then the SSL should protect your data.
