Unsupported SSL2?

  • Hi!
    I'm testing out Opera 27 Beta (27.0.1689.29) on Linux (OpenSUSE 13.2 64bits KDE)

    After doing the tricks to get Flash and HTLM5 to work, i then try to login to my web-mail at work.
    We use IBM iNotes.
    But now i get "A secure connection cannot be established because this site uses an unsupported protocol.".

    I did some search and found out something about unsupported SSL2.

    This issue also exist in latest version of firefox. In Firefox you can change settings "Security.tls.version.min=0" to get it work.
    Is there a way to do this in Opera 27?

  • SSL2 is a very old protocol, insecure and not supported.

  • I know, but is it possible to do a trick to get around this problem like you can in Firefox, or can i no longer access my IBM Lotus iNotes anymore with Opera?

  • No. You cant force Opera to SSL2, with no trick.

  • I suppose they haven't heard of Heartbleed? SSL is broken and should not be used, as there are ways to make the server give away login data.

  • May be their Domino server or Lotus is very, very, very old 😉
    May be they have no high security in their company, they might use old browsers or insecure protocols.

  • While it's easy to sit there and say "Hurr durr it's an unsupported protocol, stop using it," some of us are realistic and understand that we have no control over a remote device that is known safe and trusted but uses old SSL, which we are unable to fix. Replacing the server is not optional, upgrading it is impossible because it's not a "standard" server, and some of us aren't stupid and know how to determine whether our destination is safe or not. So the question remains, Opera, for those of us are not stupid and know about Heartbleed but still need to connect to "unsupported SSL," how do we do it? Should I downgrade to an older version of Opera, or just use a browser that will actually work with it? Some of us do it for a living.
    Edit: It persists in 29.0 on Windows.

  • try having a play with this setting see how you get on
