2.2.1.5 Secret Key

2.2.1.5 Secret Key

This slot can be used to store a secret 32-byte value or key. This key can be used with the ATECC608B-TFLXTLS’s symmetric key commands (GenDig, MAC, CheckMac, KDF, SHA/HMAC, AES).

Writing this key requires an encrypted write with the IO protection key as the write key. Therefore, the 2.2.1.7 I/O Protection Key must be set before the secret key can be written.
