This point I don’t get.
I guess you are afraid that at some point in time you are not able to download Veracrypt from a trusted Source. In this case you can keep a copy of the executable for all the platforms you need. If you are afraid that you might not be able to run it at some point in time (because dependencys are not met): this can be somehow mitigated by the Appimage version of Veracrypt bundling all its dependencies. If you think even this is not good enough: Keep a cheap reaspberry PI with Veracrypt installed arround. Just as a fallback solution to access your drives.
But if you want a cross platform solution, baked directly into Windows, MacOS and Linux … I don’t see this happening anytime soon.







I think you misunderstood me, or I was not really clear. Whatever. My point was not carrying arround the RPi everywhere all the time. But (maybe) having it as a backup if (!) you are concerned to loose access to Veracrypt at some point for some reason (and you where not able to migrate to a different solution in the meantime). If that does not apply to you: very good! No problem, no solution required.
If you decided it is to bothersome/inconvenient to install an application to (maybe) solve a problem - > that’s also totally fine.
But then I am asking myself: Does there exist any solution? Maybe not under this requirements. But then again: Having a not as convenient solution as possible, or having no solution at all. But its up to you. You decide what best fits your needs.
