CryptoCore is HCC's main encryption and security library, managed through our Embedded Encryption Manager (EEM). The EEM provides a universal, high-quality standard interface to any hardware or software cryptography implementation. This greatly simplifies the design process, makes software portable, and allows the use of either CryptoCore libraries or hardware-accelerated algorithms on chips that provide them.

CryptoCore for Renesas RA MCUs is available as CryptoCore Base & CryptoCore Pro and are included with higher-level security packages such as SNMP, TLS/DTLS and SSH. They can also be purchased independently.
