Topics

The AES library and SHA hash function library for RL78/G24 FAA are now compatible with IAR C/C++ Compiler.

While network technology and digital devices have improved in terms of performance and convenience, there is also a growing concern about security issues such as data eavesdropping, tampering, privacy violations, and unauthorized copying of copyrighted works.
Renesas provides robust cryptographic libraries for the development of various systems that require security.
