Features:

• The SparkFun ATECC508A Cryptographic Co-Processor Breakout allows you to easily add strong authentication security to your IoT node, edge device, or embedded system.
• It includes two Qwiic ports for plug-and-play functionality.
• The ATECC508A chip is capable of many cryptographic processes, including, but not limited to:
– Creating and securely storing unique asymmetric key pairs based on Elliptic Curve Cryptography (FIPS186-3).
– Creating and verifying 64-byte digital signatures (from 32 bytes of message data).
– Creating a shared secret key on a public channel via Elliptic Curve Diffie-Hellman Algorithm.
– A standard hash-based challenge-response protocol using an SHA-256 algorithm.
– Internal high-quality FIPS random number generator.
