NO_MDC (not integrity protected) message produces empty screen

[tomholub]

@tomholub, I have retested the latest master branch and there is only one that is not working properly at the moment.

This message has no description at all, where it should be flagged as NO_MDC - Missing integrity checks

@martgil can you confirm we have a message like this on e2e account and you can reproduce it there?

[martgil]

Hi @tomholub, Yes sir, the message is also included on the e2e account. The same happens for the e2e account - with the latest ios build.

[tomholub]

There's a test added in #1154 that needs to also be updated once fixed

[ivan-ushakov]

@tomholub
Am I right that we just show alert about MDC and not decrypt message at all?

[tomholub]

We should render the error into the message body just like we do for other decrypt errors - no modals.

See related #1143 - we don't want a modal here (except for collecting pass phrase), we want to render the error into the body.

And set badge to "decrypt error" in both cases.

[ivan-ushakov]

@tomholub
Looks like Endpoints.parseDecryptMsg does not work right and returns plain type. I will try to find what is wrong.

[ivan-ushakov]

} else {
  console.log('decrypt error = ' + decryptRes.error.type + ', subject = ' + subject);
  decryptRes.message = undefined;
  sequentialProcessedBlocks.push({
    type: 'decryptErr',
    content: decryptRes.error.type === DecryptErrTypes.noMdc ? decryptRes.content! : rawBlock.content,
    decryptErr: decryptRes,
    complete: true
  });
}

Here I get this - decrypt error = key_mismatch, subject = not integrity protected - should show a warning and not decrypt automatically. So error is key_mismatch, not noMdc

[tomholub]

If that's true, then key_mismatch should be showing a key_mismatch error, not empty result.

Should compare the behavior to Android app and browser extension, for that message.

[ivan-ushakov]

If that's true, then key_mismatch should be showing a key_mismatch error, not empty result.

Should compare the behavior to Android app and browser extension, for that message.

OK, so this one is not about MDC?

[tomholub]

Check how browser extension and Android app renders it and paste screenshots here, then we'll be wiser.

[ivan-ushakov]

I don't have Android app, so here is browser extension

[tomholub]

That's not what I'm seeing. You are missing a key which I added to EKM a week ago. For now the apps don't support ongoing sync of private keys, so you need to reset the extension and go through setup again.

FlowCrypt Settings -> switch to e2e account on top right -> Additional Settings (notice there is just one key) -> Experimental -> scroll down -> reset on the bottom

Then go through setup of e2e account again. This time it should load two keys. Then view the message again. You should see this:

Then log out from e2e account on iOS, go through setup there, and continue debugging on iOS.

[ivan-ushakov]

@tomholub
May I add this key to test-utils.ts and write test?

[tomholub]

Yes, it's ok to add this one. Thanks for asking.

@tomholub

I can reproduce MDC error only using this configuration:

keys.encryptedFor: ["4B5A2FFCE62D9501","4B5A2FFCE62D9501"]
error: no_mdc, subject: not integrity protected - should show a warning and not decrypt automatically

But in code for this key we use first longid as primary:

Printing description of key.ids:
2 elements
 0 : KeyId
    - longid : "ADAC279C95093207"
    - fingerprint : "E8F0517BA6D7DAB6081C96E4ADAC279C95093207"
 1 : KeyId
    - longid : "4B5A2FFCE62D9501"
    - fingerprint : "F9CEDAA4BE95A0074343E0694B5A2FFCE62D9501"

in code:

extension PrvKeyInfo {
    init(keyInfo: KeyInfo, passphrase: String?) {
        self.private = keyInfo.private
        self.longid = keyInfo.primaryLongid
        self.passphrase = keyInfo.passphrase ?? passphrase
        self.fingerprints = keyInfo.allFingerprints
    }

    func copy(with passphrase: String) -> PrvKeyInfo {
        PrvKeyInfo(private: self.private,
                   longid: self.longid,
                   passphrase: self.passphrase ?? passphrase,
                   fingerprints: self.fingerprints)
    }
}

I guess this is the reason why we get key_mismatch instead of no_mdc.

@tomholub
Do you want to change this and provide all longid to Core?

[tomholub]

I'll have to take a look myself. You can move onto another issue until I have some feedback.

[tomholub]

Please make a draft PR if you wrote a new test that can be debugged. Thanks!
