    Is there a scenario where this solution would be preferable to an encrypted zip archive?

    My guess is some heavily locked down systems. But perhaps there is more?

      ZIP encryption is quite flawed.

      That being said, I can see this being useful for a similar use case where encrypted ZIPs are useful. When malware testing, you sometimes want to avoid accidentally running the malware or exposing it to antivirus software until briefly before testing begins. Encrypted zips (as well as simple transformations like ROT13 or reversing the bytes in the file) can help control the moment the malware is unleashed. This HTML based tool could be useful for doing this in network sandboxed systems, with the specific property that it's testing the antivirus behavior when the file is marked as browser downloaded.
