K-9: Error Decrypting Email

[frojack]

Expected behavior

Expected decrypted email to show in cleartext

Actual behavior

Error Eecrypting Email message shown with icon from OpenKeyChain

Steps to reproduce

Send encrypted email to an account handled by K-9
Open email in k-9
Answer password request for decryption Key
See error message

Environment

K-9 Mail version: 5.201

Android version: Android Version 6.0 - HTC M8

Account type (IMAP, POP3, WebDAV/Exchange):
Sending Account was IMAP
Receiving Account IMAP (gmail)

Both Public keys were imported from old AGP into OpenKeyChain.
Intentionally entering a wrong passphrase gives a different message: Wrong password.
Mail sent from either account to the other (encrypted) works in Thunderbird.
Mail sent from Thunderbird also yields "Error Decrypting mail".

I think somehow callbackReturnResult is getting called twice. The second time around queuedResult is then null.

Any ideas @Valodim ?

I have multiple accounts (4) defined in K-9.Two of these have pgp keys defined in OpenKeychain.One additional account (gmail) has a key in openkeychain but is not defined in K-9.All of these accounts have the same Name.Each has a different Email Address (Obviously).

[sophisticatedpenguin]

I'm also receiving this error message. Is there a workaround? Thanks.

[jsamyth]

Go to the Google Play store and update k9.
The update is out there last time I checked. (minutes ago)

[sophisticatedpenguin]

Thanks - I have v5.202 though, and I'm not seeing an option to update.

The issue is still open which means the bug hasn't been fixed yet.
We use this issue tracker to coordinate our development efforts. Please don't use it as support forum asking questions. We have a mailing list for that.

[sophisticatedpenguin]

OK, then please could you tell me how to join the mailing list or where to find a support forum? I have searched for support but haven't been able to find it. I understand that the bug hasn't been fixed, but I hoped there might be a workaround as otherwise I can't read my emails (which is a significant issue!) Thank you, and I promise not to ask any more questions.

This error message also comes up with no further explanation when insecure ciphers are used or there is no MDC on an unsigned message. I'm currently working on error reporting, this will probably be solved along the way.

[Githubraum]

I get the same error when I try to decrypt an incoming email. However, if I forward that email to myself the received copy will be decrypted without any problem.

K-9 Mail 5.208

Do you need more information?

[Valodim]

@Githubraum I don't think that's the same issue, please open a new issue about yours

[Valodim]

As for the above stack trace, I still have no idea what caused that problem. If we're lucky, it might have been fixed along the way? Not sure.

[philipwhiuk]

Let's close it then and 🤞

Ey! I just found why I was getting a "Error decrypting" in my K9 + Openkeychain in a Xiaomi Android. Openkeychain did not have the permission to open in the background. Changed that "Android -> Settings -> Application --> Openkeychain --> Other permissions --> Open in background". Hope it helps someone.
