The MPLAB™ Code Configurator Trust Anchor Library allows quick and easy configuration     and code generation for security, cryptography, authentication, and encryption applications on     PIC and AVR devices. The Trust Anchor Library is used in conjunction with the MPLAB Code     Configurator Crypto Authentication Library and the Trust Anchor CryptoAutomotive™ security ICs.     It provides a way for you to implement security into existing systems without requiring costly     redesigns.
