I mean, we could in both apps, but I don't see the point. It would add complexity to the install process and add more places things could go wrong. The apps are designed to work with encrypted keys, and should only be used with encrypted keys.That said, I gather that it's possible to check that a decrypted key is valid (as that titlekey site does), so if the app is expecting an encrypted key, it could potentially test whether the entered key was a valid decrypted one and display an appropriate error.
