    Tech Xplore[^]:

    The encryption algorithm GEA-1 was implemented in mobile phones in the 1990s to encrypt data connections.

    You mean it's not just everyone around you that can hear your phone conversations?

      Hmmmm, The best place to hide information is probably in plain sight. Case in point: The Chris Maunder Gravatar icon: https://www.gravatar.com/avatar/**a67a31d131918d8fc68180c034bed045**.jpg?d=identicon&s=150&r=pg Although there are 2^128 possible MD5 combinations and there are around 360 million domain names... only a fraction of those have MX records (mail server records) which will greatly reduce the search space. You can further reduce the search space by only searching through the top 100 or so email providers. Permutation through the range of 1-4 letters [n][n][n][n]'@codeproject.com' we can quickly compute that a67a31d131918d8fc68180c034bed045 is the MD5 hash of chris@codeproject.com Gravatar icons are a security risk and can be used for sitewide farming of emails. Don't shoot the messenger. :) Best Wishes, -David Delaune P.S. By the way I searched the codeproject forums first to make sure that Chris has publicly shared his e-mail before making this post. If this post violates any site rules just delete it.

          I almost used yours for the example but it looked like you would want it remain private. :laugh:

            Kent keeps publishing his password; it seems he's a security exhibitionist

              Be happy... it could be worst... just imagine he would be another kind of exhibitionist... Like Sean with the mankini... X| X| :laugh: :laugh: :laugh:

              M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.
