    Would the encryption of winzip (full strength) be as strong and secure as
    the secure link you establish between your browser and a secure server. Eg.
    when the little padlock pops up to indicate your on a secure server?

    WinZip ver 9.0 uses 128-bit and 256-Bit AES encryption (about as
    industrial-strength as you can get). Browser uses 128-bit encryption.
    If you believe neither program has back-doors, then WinZip is probably
    more secure.

    Depends on the number of bits and method used.

    Winzip
    128- and 256-bit key AES encryption
    is better than 40/56bit https , similar to 128 bit https some https may
    be 256 bits as well..

    They are also 2 different things, with different sorts of risks.

    You could start with
    http://www.winzip.com/whatsnew90.htm
    and
    http://searchsecurity.techtarget.com/sDefinition/0,,sid14_gci214006,00.html
    not forgetting Google.

    In addition to the number of bits of key that the algorithm has, you
    must also consider the password you choose. If you pick a 26 character
    password made up of the lower case letters plus a space character, you
    have limited yourself to an equivalent 124 bits of password entropy so
    a 256-bit key algorithm won't buy you anything beyond the 128 bit key.
    If your password is English-looking (every 4th or 5th character a vowel
    and there are more t's n's and s's than j's, v's and q's then your
    effective space is even worse. In this case, a computer picking a
    close-to-random 128-bit key will be more secure than your password in
    combination with a higher-bit key algorithm.
