1842629 - No longer attempt to repair/re-init the OpenPGP secret storage if the automatic passphrase doesn't work

Status: RESOLVED FIXED

(MailNews Core :: Security: OpenPGP, enhancement, P2)

Description

[Kai Engert (:KaiE:)]

If the feature to use individual OpenPGP secret key passphrases (bug 1679278) has been enabled, then we should never automatically attempt to re-initialize the secret key storage.

If mail.openpgp.passphrases.enable is set to true, the user might no longer be using that automatic passphrase anyway.

(We had introduced the re-init of the automatic passphrase because of bug 1790610 and the related broken profile import feature.)

Actually, I think that TB 115 and later should never re-init (move away) the secring.gpg file,
even if the pref is false.

Because the user might have had the pref enabled previously, set passphrases, then disabled the pref again.
Our code won't show the UI for managing the passphrase, but it would still correctly handle prompting for that passphrase.

Given that 115 doesn't suffer from the original bug (described in bug 1790605), it should be unnecessry to recreate secring.gpg

I'll wait until the work on bug 1835786 has completed.
Afterwards I'll request review on this cleanup.

Is this still wanted for 115?

Actually, I'm temporarily withdrawing my approval request.

Looking at the patch just raised some uncertainty.

I want to go back and doublecheck one more scencario.
