Yes, you can encrypt files using GPG and then pad them with additional data or formatting.

The process doesn't automatically add random padding to encrypted files like GPG does. You'll need to implement your own method to insert random characters at the beginning and end of the .zip file. Adding padding could be effective but may not be necessary depending on your security needs.
You check the file's metadata or the archive's properties to see what padding characters are used.
You seem to be misunderstanding the question: I have an unencrypted .zip file I want to encrypt it with something like GPG Since .zip files have a standard header, it is possible to analyze the first 'n' bytes of the encrypted file to try and crack the encryption If there is a random few bytes of information at the start of the file, it makes that analysis much more difficult. This isn't a new concept, it's a pretty well defined problem (and some cryptography methods actually require padding to make a message long enough to be encrypted). I'm just asking if there's a way to pad files with GPG (or a homebrew solution to accomplish the same thing).
