K-9: K9mail can't find public keys of recipients

[MaxLanar]

Expected behavior

Successfully encrypt messages for recipients with an associated key in Openkeychain (OKC).

Actual behavior

When I try to send encrypted messages to recipients with a public key in OKC I get this :

"private mode is enabled but some recipients don't have keys." and the dots of the lock icon don't become green anymore.

I've triple-checked the crypto settings of the account and the recipient address of course.

It used to work before but not anymore, I don't know what triggered that behavior.

Steps to reproduce

1. create a new mail, fill recipient
2. Select Encrypt
3. Tap on the send icon

Environment

K-9 Mail version: 5.203 from fdroid

Android version: cm-13

Account type : POP3

It's it possible this is a capitalization issue? Fix for that one is coming up in OK.

The private mode thing sucks as it is, I'm just not sure how best to do this and didn't want to trial and error iterate here too much

[MaxLanar]

A capitalization issue ? You mean if I entered an address like this [email protected] ? Then it's not, I checked and re-re-check the recipient field each time and tested with different address, the issue always comes up .

[softgenix]

I have the same issue, as described.
Setting lock to "Encrypt" fails to send the message and gives the error, "Private mode is enabled but some recipients don't have keys!."

But, using "Encrypt if possible," successfully encrypts and sends the messages.

I have K9 v 5.203, imap, Android 6

For every email address in K-9 Mail's recipients, is there a key in OpenKeychain that contains a User ID with that email address?

[MaxLanar]

I don't know if it's what you're talking about, but the corresponding public keys for every address I tested have the email address under "Advanced -> Identities" (words translated from french) In OpenKeychain.

[dschuermann]

@MaxLanar yup I meant that. Sry for my technical words. Can you try to identity which recipient actually results in the error you described in the bug report by adding them one by one and testing? Maybe disable internet connection before so that the emails are send and then removing them from outbox.

Another idea: Is any of these keys revoked or expired?

[MaxLanar]

What do you mean by "by adding them one by one and testing" ? I don't understand what you exactly want me to do.

None of the keys are expired or revoked.

[MaxLanar]

@dschuermann In fact the testing I did was already with one recipient at a time (only one recipient in the 'to' field).

Dupe of https://github.com/k9mail/k-9/issues/1655 I think.

[richfirst]

I had to revert to 5.0.1 as have nothing but issues relayed to encryption/decryption,

First, I'd like to say, a great number of people, myself included, have red/green color blind issues, and to try to relay info by these, or even other colors will not work for me, I can't tell the difference. Until I read these bug reports, I didn't even know there were different colors.
Please change to something that works for color impaired purple.

Second, I can no longer decrypt any received messages: I use open key chain, I an promoted to enter my password, and then I an shown the encrypted pgp gibberish with old k9,i see the gibberish behind the prompt to enter my password, and then when it's in I see the decoded message.
The new k9 is unusable.

Good idea. I'd suggest to open a new issue for this though.
And as a suggestion how to fix it: The padlock could be open (when it is orange). It already displays a cross when it is red, so it should just also be an "open lock".

Also for your other problem open a new issue. It does not seem as if this would have anything to do with this issue. (public keys do not seem to be the problem)

[philipwhiuk]

2189 for the colour impaired issue.

As for the other one @richfirst's description of the actual issue is too vague - it doesn't say why they can't be decrypted. But yes - if it's different please open a new issue.

This is a bug tracker, not a support forum or a rants thread.

[dschuermann]

@MaxLanar @softgenix Can you try OpenKeychain 4.2.4 I just pushed to Google Play? We recently fixed a problem regarding the selection of public keys.

[MaxLanar]

Hello,
@dschuermann Still exactly the same behavior with OpenKeychain 4.2.4 (from fdroid) for me. Nothing changed.

Probably one of the best typos I've seen all day.
