Originally, we developed ocrypto for a secure firmware update mechanism, for a microcontroller-based edge gateway. When Apple announced HomeKit, we have started optimizing ocrypto for that home automation protocol. Since then, ocrypto has become the reliable cryptographic foundation for dozens of HomeKit products, from thermostats and sprinklers to door locks, cameras and televisions.

Thanks to customer requests, some non-HomeKit functions have been added over time.
