Update CSR Example

Updating CSR demo to avoid locking the ATECC on first run, unless the LOCK_ATECC boolean is set by a user. Example now generates a new internal private key instead of a public key.

To use in CircuitPython, simply install the Adafruit CircuitPython bundle.

Initial Release: CircuitPython ATECC

CircuitPython Driver for Microchip's ATECCx08 cryptographic co-processors with secure hardware-based key storage. This library is based on the ArduinoECCX08 library.

• adafruit_atecc: Hardware/chip driver and interface
• adafruit_atecc_cert_util: Certificate builder utility. Currently supports generating a Certificate Signed Requests (CSR) but could be modified to generate/build a Self-Signed Certificate or JWS token.
• adafruit_atecc_asn1: *cert_util-specific ASN.1 tools and utilities for certificate generation.
  • Example of generating a Certificate Signing Request with this module
