Play Integrity Test: How to Check your ROM's Test Key/Private Key

Guide: droidwin.com/how-to-pass-play...
As per the new development, your ROM must be signed with a Private Key [releasekey.x509.pem] from the developer, if it is signed with a Test Key [testkey.x509.pem], then your device will not be able to pass the Play Integrity Test. And that's not it.
The Kernel should also not have any banned string [list is given in the guide]. If your kernel does have a string which is part of this banned lisst, then your device will not be able to pass the test, even if it has a Private key.
So in this video, we will show you how to perform both these tests so that you may then mould your decision accordingly. If your device has a Test key, then there's no point in flashing the module or using a custom fingerprint/build.prop because it will not be able to pass this test, all thanks to the key, irrespective of the fingerprint you're using,
