How to Create Password Protected ZIP in Linux

Once installed, you can use the zip command with -p flag to create a password protected zip archive called from the directory of files called ccat-1.1.0 as follows.

$ zip -p pass123 ccat-1.1.0/

However, the above method is absolutely insecure, because here the password is provided as clear-text on the command line. Secondly, it will also be stored in the history file (e.g ~.bash_history for bash), meaning another user with access to your account (more especially root user) will easily see the password.

Therefore, try to always use the -e flag, it shows a prompt allowing you to enter a hidden password as shown.

$ zip -e ccat-1.1.0/

    Hello Aaron,

    I thought it would be helpful to mention zip --help since there are different flags for the different versions & distros, but I believe --help is universal.

    For instance, my system / zip gives me -e for encryption and ~20 other flags, but not -p or -P so I know not to bother with them.

    Thanks for the article & excuse to play with something new. 8)

    On Fedora 30, was necessary to:

    # zip -P password -r directory/
  4. Prabhat says:
    $ zip -e ccat-1.1.0/     is incorrect

    it should be

    $ zip -er ccat-1.1.0/

    this wasted my 30 mins

      In our case, the same command worked perfectly on Ubuntu distro, may be some options differ in different Linux distros…

  5. dlchambers says:

    Password option is uppercase P, not lowercase as shown above.

  6. Werner_Holt says:

    It doesn’t work option -e with your written method. Right syntax is:

    # zip -e ccat-1.1.0/*

    Do not forget about "*" at the end of line! Without "*" zip makes an archive including all files and folder above ccat-1.1.0 folder.

    • Aaron Kili says:


      Many thanks for this useful info, we will put this into consideration.

      • Werner_Holt says:

        Something strange, maybe I caught the bug yesterday. Now, it is working! But only when the folder ccat-1.1.0 doesn’t include other folder inside. If it has folders with files and so on, you must use option -r (“recursive”).

        This way:

        $ zip -e -r ccat-1.1.0/

        Do not work under root user! Without "#".

        Sorry for my false warning before!
        Thank you for your article!
