#CryptoAuthentication OpenSSL Engine

##Overview This is an OpenSSL Engine implementation using ATECC508A for ECC key storage, ECDSA sign/verify, ECDH, and FIPS Random Number Generator

The implementation integrates the Microchip ATECC508A into the OpenSSL ENGINE API to provide secure hardware key storage, CAVP certified random numbers, P256 ECDSA & ECDH, and secure storage for data.

This project will integrate the key creation and import capabilities of the ATECC508A into the OpenSSL key creation and certificate creation process.

Also, secure key storage for RSA keys are implemented using the encrypted read/write feature of the ATECC508A.

###Supported Cipher Suites Many ECDH(E)-ECDSA and ECDHE-RSA cipher suites are supported with the OpenSSL Engine for ATECC508A implementation.

Details for cipher suites can be found here
