title: Andoid 12 Keystore user_0 missing foder
body: <p>I'm currently doing a study on application forensics on Android 12 API 31. in this study I need to use a private key from Keystore that I can find no problem in Android 11 that is usually located in &quot;/data/misc/keystore/user_0/&quot;. but in Android 12 the folder of &quot;user_0&quot; cannot be found there, all I can find is a file named &quot;persistent.sqlite&quot; DB file. is there any updates am i missing on the documentation on AOSP or maybe that i miss concept the understanding of Keystore persistent.sqlite file</p>
