Once you 'lock' the chip with your details, you can use it for ECDH and AES-128 encrypt/decrypt/signing. There's also hardware support for random number generation, and SHA-256/HMAC hash functions to  greatly speed up a slower micro's cryptography commands.\n\n### Features:\n- Cryptographic co-processor with secure hardware-based key storage\n- Protected storage for up to 16 Keys, certificates or data\n- ECDH: FIPS SP800-56A Elliptic Curve Diffie-Hellman\n- NIST standard P256 elliptic curve support\n- SHA-256 \u0026 HMAC hash including off-chip context save/restore\n- AES-128: encrypt/decrypt, galois field multiply for GCM\n\n## How to contribute \u003cimg src=\"https://electroniccats.com/wp-content/uploads/2018/01/fav.png\" height=\"35\"\u003e\u003cimg src=\"https://raw.githubusercontent.com/gist/ManulMax/2d20af60d709805c55fd784ca7cba4b9/raw/bcfeac7604f674ace63623106eb8bb8471d844a6/github.gif\" height=\"30\"\u003e\n Contributions are welcome! \n\nPlease read the document  [**Contribution Manual**](https://github.com/ElectronicCats/electroniccats-cla/blob/main/electroniccats-contribution-manual.md)  which will show you how to contribute your changes to the project.\n\n✨ Thanks to all our [contributors](https://github.com/ElectronicCats/ATECC608A-Croquette/graphs/contributors)! ✨\n\nSee  [**_Electronic Cats CLA_**](https://github.com/ElectronicCats/electroniccats-cla/blob/main/electroniccats-cla.md) for more information.\n\nSee the [**community code of conduct**](https://github.com/ElectronicCats/electroniccats-cla/blob/main/electroniccats-community-code-of-conduct.md)   for a vision of the community we want to build and what we expect from it.\n\n### Maintainer\n\nElectronic Cats invests time and resources in providing this open-source design design, please support Electronic Cats and open-source hardware by purchasing products from Electronic Cats!\n\n\u003ca href=\"https://github.com/sponsors/ElectronicCats\"\u003e\n  \u003cimg src=\"https://electroniccats.com/wp-content/uploads/2020/07/Badge_GHS.png\" height=\"104\" /\u003e\n\u003c/a\u003e\n\n## License\n![OpenSourceLicense](https://github.com/ElectronicCats/AjoloteBoard/raw/master/OpenSourceLicense.png)\n\nHardware released under an CERN Open Hardware Licence v1.2.
