    You can't unless you arrange yourself a crypto peer somewhere (or use only SSL services :) ).

    There are free anonymous proxy solutions that support encryption and of course you can set up your own.

    WiFI encryption is between 'two-end-points'. For the home user, this means
    security between the computer and the router, thus protecting your data from
    the neighbor's view. At the hotel (just like other hot-spots) the router needs to
    be 'open' so that everyone can connect. These sites can not be secured per the above.

    The other end-point model is the formal corporate infrastructure, where you're
    literally behide the firewall and have access to the LAN. This link is performed using
    VPN hardware or software. Your WiFI may be still active, but the real security is the VPN layer.

    That being said, it is possible to secure your EMAIL regardless of where you are connected.

    You need an Email Client program like Thunderbird or Outlook Express (if you still trust it :blackeye: )
    A PGP implementation to do the encryption/decryption
    an to distribute your public key to your correspondants
    The process is to create a message, encrypted, and paste into the outbound
    email. I use FileAssurity from ArticSoft

    Could you give me some links to some anonymous proxy solutions?

    Backup a moment. Regardless of how you connect to the ISP, all websites
    asking for personal/private/monitary information (ie banking, online purchases),
    OUGHT to be using SSL. This says, the URL should start with https://
    and your browser should confirm that encryption is active by some icon in the
    window frame (eg: the lock symbol).
    If this is NOT TRUE, shame on you - - you just gave away the store :blackeye:
    If it is true, then the session is encrypted end-to-end and it's a real pain to get the data; your data is safe.
