Crypto Benchmark on STM32F3 MCU
ARM Cortex-M4 @ 64 MHz

This benchmark conducted on NUCLEO-F303RE development board with STM32F303RE MCU 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 STMicroelectronics STM32F3 microcontroller.
