AndroidKeyStoreSigningKey

class AndroidKeyStoreSigningKey : JwsProcessor(source)

A hardware-backed JwsProcessor that signs and verifies data using keys stored in the Android Keystore. Key material never leaves the secure element (TEE or StrongBox) — private and secret keys are generated and used entirely within the secure hardware.

Use getInstance to look up an existing key, or getOrCreateInstance to obtain one and generate it on first use.
