Hi folks, there is consensus that some algorithms/ciphers (e.g. RC4) allowed by default should not be considered secure, though because of interop issues, they cannot be removed at this point.
The problem with this is that people may think they are using a secure connection while in fact, someone could eavedrop. To reduce the impact of this problem, I propose to implement a visual indicator for when a connection should not be considered secure. The goal is not to show an OMG-BEWARE message but instead to not show a (falsy) "secure" indicator. Currently, there is a padlock shown for HTTPS connections in Firefox (see first part of [1]). For insecure (but encrypted connections), there are three options: A. Make it look like an HTTP connection: No padlock but the "world" icon, no "https:" string. B. Indicate a broken padlock (e.g. with a big fat red bar crossing the padlock), show the "https:" string (like in the second part of [2]). C. Make it look like an HTTP connection but not lie about the protocol: Use the globe icon but show the "https:" string (like part 3 of [1]). (A) is lying but mostly obvious, i.e. it says that the user is not on an encrypted connection and should act accordingly. (C) is non-obvious because the globe can mean anything and the "https:" may confuse / mislead people who are used to looking for this string. (B) may not be completely obvious but it shows that there is something wrong although you are on an encrypted connection - I prefer this last option. I understand that this is not dev.firefox but I think this is a solution that most can live with for the foreseeable future (this is no long-term solution!). Do you agree? (The UI resolution can also be adopted for HTTP/2.0 unauthenticated HTTPS, and on any connection where the user bypassed any blocking mechanism, e.g. for failed cert checks. It may require changes to the identity panel as well to explain why the connection is shown as "unencrypted".) Best regards, Florian Bender [1] http://imgur.com/C6wOlRm Am Samstag, 14.
