(MailNews Core :: Security: OpenPGP, defect)

Description

[Lasana Murray]

The continue button should be disabled until the user has actually selected a key.

Make the continue button disabled by default.

This happens only if using the menu item "Import secret keys from file" fro the OpenPGP Key Manager.

Thanks for finding this issue, but unfortunately this solution doesn't work as it breaks the "Add Key" subdialog.

I think the better approach would be to disable that button when the dialog loads directly on the import screen: https://searchfox.org/comm-central/rev/4eb14a03690b8d6bbe53853a33b6e09d330a05ea/mail/extensions/openpgp/content/ui/keyWizard.js#118-122

This is what we're using in the wizard when switching between sections.
`kDialog.getButton("accept").setAttribute("disabled", true);`

I disable the button closer to the code that displays this specific section.

Question: Is the plan to eventually remove the key manager from the main menu? Currently it's a little inconsistent, clicking back on this same "import secret key" screen takes you to the section used in the account settings rather than the key manager dialog.

Indeed, we have bug 1662282 for it.
The plan is, most likely, to move this whole key manager into a tab.

The disabling of the button is correct, but I think we should move it in here: https://searchfox.org/comm-central/rev/f6018345454b019bd41c50da80c2bb34f042db86/mail/extensions/openpgp/content/ui/keyWizard.js#119

The wizardImportKey() method, normally has this stack trace when interacting from withing the dialog: wizardContinue() -> switchSection() -> wizardImportKey().
The "Continue" button is disabled whenever the wizardContinue() method is called, which is hooked to the Continue button itself.
Disabling the button in the wizardImportKey() is basically like disabling it twice if the user is using the dialog from the first screen.
Not an issue, but just unnecessary.

Disabling the button on init() only when the code is directly requesting the import section makes more sense.
We should also add a comment to explain why we're doing that.

Disabling the button on init() only when the code is directly requesting the
import section makes more sense.

Just a thought on this:
Wouldn't it be more idiomatic to have the accept button disabled by default and only enable it when the conditions for "continuing" are satisfied?

Move the change to the init function.

Sure, I'm okay with that.
Up to you if you want to take on the burden of updating the dialog, which is currently used by both the e2ee page as a subdialog and by the Key Manager as a regular dialog.
That's why there are some strange approaches and timeouts in it, in order to be able to use the same source in both scenarios.

Maybe not worth uplifting.
