When incorporating a secure authentication IC part of the CryptoAuthentication family into an embedded system, developers must employ specific commands and functions recognized by secure authentication ICs in addition to facilitating communication between the secure authentication IC and a microcontroller or microprocessor. There is a C library for that : CryptoAuthLib. This Chiptorial explores fundamental concepts explaining how the CryptoAuthLib Library renders Microchip's secure authentication ICs independent of any specific microcontroller or microprocessor for immense flexibility in the embedded designs. We delve into the components that constitute the CryptoAuthLib library, elucidating how it can be effectively integrated into an MPLAB Harmony project. Lastly, we briefly overview key folders within the library, hosted on GitHub.
