addTrustedScreenReaderSigner

This option allowlists the signing certificate of a trusted screen reader (e.g. TalkBack). All screen readers signed with this certificate would then be accepted by App Shielding.

Multiple addTrustedScreenReaderSigner options can be added to allowlist multiple applications.

• Type: fingerprint

• Default Value: N/A

• Multiple allowed: Yes

• Required: No

• Depends on: addTrustedScreenReaders

The value to add for a given screen reader can be obtained with a tool called PubkeyHash that can be found under tools/PubkeyHash.jar provided that the APK file of the screen reader is available.

The tool can be run like this:

java -jar PubkeyHash.jar file.apk

The output of this command is the value that should be used for this option.
