Crypto Benchmark on RX63N MCU
RXv1 @ 96 MHz

This benchmark conducted on Renesas Starter Kit+ for RX63N-256K (RX63N-256K-Starter-Kit-Plus) will help you in qualifying performance of CycloneCRYPTO (Cryptography library), CycloneSSL (TLS 1.3 & DTLS 1.2 library), CycloneSSH (SSH library with SCP & SFTP protocols), CycloneIPSEC (IPsec/IKEv2 library) and CycloneTCP (TCP/IPv4/IPv6 stack with secure protocols like HTTPS, FTPS, MQTTS, Secure WebSocket, Secure CoAP, Secure Modbus/TCP, SNMPv3...) running on Renesas RX63N microcontroller.
