Is there a free file-compressing app that you would you suggest, one that will have an option to set a password for protecting the compressed files?

Thanks for all the help guys. I have a feeling that .dmg might be the best cause it will open on any Mac without needing to have an app. Isn’t that correct?

From the other thread
You can create a zip file with a password from the command line. e.g.
Code:
zip -er test.zip *
will create a password protected file called test.zip (after prompting for the password) that contains all the files in the current directory.

You can decrypt the file with macOS's Archive Utility.

do you know if password protected zip files as secure as encrypted dmg files?
Disk Utility offers 128-bit AES and 256-bit AES encryption

Zip files can be encrypted using Zip 2.0 (Legacy)/ ZipCrypto encryption, 128-bit AES and 256-bit AES

For the moment, 256-bit AES encrypted ZIP files can not be opened with the default Archive Utility on macOS or iOS.
