multiple pubkeys per email - Importing pub keys manually

[tomholub]

Importing pub keys
Here we can have two cases:

1. key with a single user id: for example key for A@flowcrypt.test It's a simple case.

Here we have the same behavior as before.

Not the same as before. Before, you were always the public key. Now, need to compare it to existing public keys of that one recipient by primary fingerprint.

• if the key is not present in the list of keys of that one recipient, add it to the list
• if already present, then compare by lastModified. If the offered key is newer, then replace the existing key by the newer key. If older, then do nothing.

2. key with a few user ids: for example key for A@flowcrypt.test, B@flowcrypt.test

Here we have 2 theoretical recipients: A@flowcrypt.test, B@flowcrypt.test. Should I add 2 entries to the local database

1| FINGERPRINT| A@flowcrypt.test | KEY
2| FINGERPRINT| B@flowcrypt.test | KEY

I suppose here we're talking about manual import of potentially many public keys? Where user is just importing keys without further interaction, and not indicating for which user they are importing the keys. Let's do the safer thing - only import for primary user id. So that would be one entry (subject to the same procedure with list handling as above). We could reconsider it in the future.

I'm reopening it. It will relate to manual import

[tomholub]

In the situation above, I've described manual import in the settings.

I suppose manual import when we receive pubkey over a message could work the same - go by primary email. On browser extension we currently show an email address input where the primary user id is prefilled. Does Android do the same? Or it doesn't give the user any choice who to import for?

Could you attach a screenshot? To be sure we are talking about the same things

here the text input that contains email address:

Android doesn't show that input field, just saw it. That's fine. Can go by primary uid of that pubkey, as long as that one is visible.
