  • compressing and password protect file group individually?

    In Ubuntu, right now I'm selecting each individual file (left clicking),
    right clicking and choosing compress, keeping same file name, and then entering password, then create but this is going to take a long time for
    well over a hundred files! I don't want to create a new archive name
    for the group as this will mean that all would have to be unzipped
    later. I just want to keep original file names. thanks

    Try this:

    #!/usr/bin/env bash
    for f in *; do [[ -f "$f" && ! "$f" =~ \.gz$ ]] && gzip -9 "$f"; done

    ,gz doesn't support passwords!

    You can put a set of files into an archive and access them
    with Archive Manager from Thunar or Nemo.

    If you list the files in the archive, you can hold down
    shift-ctrl and mouse click the random selections you
    want decrypted and decompressed.

    In any case, encryption always comes after compression,
    as encrypted items don't compress. Either a tool
    does the whole job for you (compress then encrypt),
    or you can use two tools, a compression tool first
    followed by an encryption tool.

    I can use 7z instead of p7zip package, to work with .7z archives.
    Here I have put three files into a compressed archive that
    is encrypted with AES256 plus an 11 character password. Then, I
    randomly accessed two of the files, by using shift-ctrl and
    the mouse pointer to join the second file to the set of them
    I was building. I am then asked for the password, by the
    Archive Manager.

    The rectangle at the top, is a picture of a Windows tool examining
    the same archive file, and the + signs indicate encryption is present.

    I do not have to unpack hundreds of files, to just extract
    one of the files by using Archive Manager.

    You can automate it from Terminal instead of doing each file manually.

    In the folder with the files, run something like:

    Bash
    for f in *; do [ -f "$f" ] && zip -P yourpassword "$f.zip" "$f"; done

    That makes a separate password-protected archive for each file, while keeping the original filename (document.pdf ' document.pdf.zip).

    If you want stronger encryption, use 7z instead:

    Bash
    for f in *; do [ -f "$f" ] && 7z a -p"$PASSWORD" "$f.7z" "$f"; done

    So yes, you do not need to compress them one at a time through the right-click menu.
