Currently, the Pico HSM supports AES key generation, encryption, and decryption. However, the generated AES keys are set to be "never extractable" by default, which restricts the flexibility of using these keys in certain scenarios. For example, in a backup or key migration process, it is necessary to export the AES keys securely.
