AppleKeychainSigningKey

class AppleKeychainSigningKey : JwsProcessor(source)

A hardware-backed JwsProcessor that signs and verifies JWT payloads using keys stored in the iOS/macOS Keychain.

Keys are stored in the Keychain with kSecAttrAccessibleAfterFirstUnlock, making them hardware-bound to this device (they cannot be migrated via iCloud/backups).

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