Kypass 4.5.2 crash when trying to autofill login

Post by JörgRennefeld » Sun Apr 21, 2019 11:28 am

On my iPhone8 with iOS 12.2 Kypass 4.5.2 crashes when I want to autofill a login form from Safari or another app.
Opening the app itself from springboard works fine.
I have filed a bug on the GitHub page: https://github.com/redbug26/kypass/issues/7
See the video on google drive: https://drive.google.com/file/d/1B3INMMRrDG_ahWAi_ZKOvK-D0mVrYuYP/view?usp=sharing

Anyone else observing this issue?
I previous versions of Kypass it took sometimes two or three attempts to successfully fill a login, but this time it always crashed. I could not successfully fill one login form.

Let me know if there is something I can do to help track this down. I am not an iOS Developer but with some instructions I could probably provide some debug data.
Without the autofill working its really cumbersome to use.

Upon that notice, I have tried with a different database, it is small ( 2.5 kiB) compared to the one causing the crash (900kiB).
With this small databse the autofill works and does not crash.

So could it be an issue with the specific database?
I doubt it. as I can open it regularly without and issue.
Or is it iOS terminating Kypass in that setting for some resource constraint or else?

Which encryption method are you using?
Argon2?
Autofill modules have size limits in memory.

In the information dialog it shows Derivation "Argon" for both Databases I have tried.
Is there a difference between Argon and Argon2?

Is there a way to find out if iOS is terminating the autofill module for overstepping its memory limits?
Would it be possible for Kypass to circumvent that or at least display a warning for databases that are too large so that the user at least knows?

That's something The developer has to answer.

Yes. Argon is argon2 ;)
For a warning message, it’s a good idea

It’s a big issue for me. I have a database of 563kiB and derivation is Argon and kypass is crashing always while autofill.
If new autofill can’t use a big database, could you please add an option to use the old autofill which was working well?

You van just turn off auto fill in the settings. This will leave it to the old system.
But you should think about what you want.
You are using a extreme memory using algorithm and that’s the problem for the autofill.
