wolfSSL support for the ATECC508A/ATECC608A crypto coprocessor

wolfSSL embedded SSL/TLS support the latest Microchip ATECC508A and ATECC608A I2C cryptographic coprocessors. Not only is wolfSSL compatible with CryptoAuthLib, wolfSSL has also been tested on both the 508A and the 608A.

Prerequisites:

Examples:

  • wolfSSL uses PK (Public Key) callbacks for the TLS crypto operations
  • wolfCrypt uses the WOLFSSL_ATECC508A macro to enable native wc_ecc_* API support
  • wolfCrypt also uses the WOLFSSL_

The README.md and reference PK callbacks can be found here: https://github.com/wolfSSL/wolfssl/tree/master/wolfcrypt/src/port/atmel

Additional demos for wolfSSL TLS Client/Server and wolfCrypt test/benchmarks can be found:

Preprocessor Macros:

  • WOLFSSL_ATECC508A
  • WOLFSSL_ATECC_PKCB
  • WOLFSSL_ATMEL

PK Callbacks:

wolfSSL’s TLS layer PK callbacks expose API’s to set ECC callbacks. These are enabled with: #define HAVE_PK_CALLBACKS or ./configure --enable-pkcallbacks.

Reference API’s:

  • atcatls_create_key_cb
  • atcatls_verify_signature_cb
  • atcatls_sign_certificate_cb
  • atcatls_create_pms_cb
