Are there plans to add support for password protecting the zip file itself?

[MLyons10]

I know that you can password protect individual files, but I was wondering if there were any plans to add support for password protecting the zip file itself.

Also, are there any concerns or issues surrounding password protecting a database backup file? I assume the password is stripped when it's exported from the zip file?

Thank you very much for an incredible resource and for everything that's gone into it...
