Wickr-- so this one is specific to iOS.
If you have the keychain, which means
you did a full file system extraction,
you can decrypt the data.
The important step is that you parse it correctly.
And I realize I work at Cellebrite.
However, I've written a blog for GrayKey,
and they have it if you're a customer.
If you look on the website, it will show you
how to properly load GrayKey extractions
into Physical Analyzer.
What you want to make sure you do
is that you load the keychain plist as well
as the extraction.
Now, with Axiom, I've heard several students say
that you sometimes have to add the keychain
and parse it, and then load the extraction and parse it again.
If that's still true, I'm not sure.
I don't have many GrayKey extractions to test.
But just make sure you are parsing your full file system
data correctly.
If you create it with Premium, you
double click on the UFED shortcut.
It will work.
If you created it will Checkmate, same thing.
Click on the UFED shortcut.
It will work.
You will have parsed information.
