1890732 - Improvement: warn users of GPG private keys expiry dates in advance

Status: RESOLVED DUPLICATE of bug 1840861

(Thunderbird :: Untriaged, enhancement)

Description

[mprower]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0

Steps to reproduce:

• Go to "End-to-End Encryption" settings and either
• Create a personal GPG key with an expiry date in the distant-ish future
• or import an existing valid key

Actual results:

When inching closer to the date the private key is no longer valid, users are not notified and tend to forget to renew their secret keys. This could mean entirely losing a key and having to generate a new one, if the deadline is missed for any reason.

As a results, users can get even more frustrated towards GPG. I have some people told me that email encryption was not worth the tedium entirely, for instance.

Expected results:

Thunderbird should check the validity of the user's private GPG keys and warn them that they will expire soon, preferably repeatedly (one month prior, 15 days priori, 1 week, each day then…).
