It has been suggested at Oracle that the zip man page should warn about weak encryption when using the --encrypt option and it should recommend a more secure solution.

    Hi Jan,

    Beta Zip 3.1d is about to be released and includes AES strong encryption in addition to the admittedly weak original zip encryption. The man page has been updated to note that use of the original traditional zip encryption is no longer recommended because it is relatively weak.

    We haven't considered having Zip put out a warning when the user selects traditional encryption, assuming the user understands the choice being made and has read the manual or the extended help that notes the weakness. No other major zip does that as far as we know. A user really should take the time to understand the strength of the encryption used before relying on it.

    Zip 3.1d is expected to be a release candidate and should go out in a week or two. We expect the release to follow in a few weeks.

    Regards,
    Ed Gordon
