2. After connecting Convert and push the certificate file to WSA.

   1. openssl x509 -inform DER -in burp.der -out burp.pem
   2. openssl x509 -inform PEM -subject_hash_old -in burp.pem | head -n -1 Output result will be something like 9a5ba575.0

After installing the magisk_overlayfs module, Magisk has stopped working, and I am unsure why. I have attempted various solutions, but the issue persists. Any assistance would be greatly appreciated.

I faced the same issue. But using kernelsu instead, solved the problem.

@l1roun Its working fine for me I'm using Magisk v26.4 with Magical OverlyFS v3.2.2 by HuskyDG

did you manage to run mobsf dynamic analysis (mobile security framework) with wsa?

@h1roun @omair2084 There's an issue with the ZIP that HuskyDG released for version 3.2.2.
If you compile the latest yourself (easy, just follow the readme), and zip the files in the output folder, you can install it on version 27.0.

And just adding to this write-up, you don't really need the third step to install the certficiate via the UI...
If you want to access the WSA device settings to confirm the cert was installed, you can use this: adb shell am start -n com.android.settings/.Settings

Thankyou, this works. Just fork and run actions.
