Is there some other archiver with proper encryption?
There is probably some cli command that can do that but the default zip with -e only encrypts with original (weak) encryption. I haven't cared much about encryption with zip. Just been part of cracking it for our own purposes.
If you use an archiver like "ark", you can choose AES256 for your zip archive.
The problem I think Daniel is facing is that his customers should not have to install any cumbersome unzipper to get things rolling. But you can extend the service menu in dolphin with quite a few things. Among them is one with ark but I'm not sure if it can be change encryption.
As a short test. Two zip files. One made with ark and AES256 and the other with zip -e.
$ file *.zip 1.zip: Zip archive data, at least v5.1 to extract, compression method=AES Encrypted $ 2.zip: Zip archive data, at least v2.0 to extract, compression method=deflate
