The wolfSSL embedded TLS library has support for most of the STM32 microcontrollers and for their hardware-based cryptography (AES/HASH/PKA) and random number generator (TRNG). Here are the STM32 processors we currently support:

STM32F2 STM32F4 STM32F7 STM32F1 STM32L4 STM32L5 STM32WB STM32H7 STM32G0 STM32U5 STM32H5

wolfSSL offers STM32Cube Expansion Packages for the STM32 toolset, letting users pull wolfSSL and wolfSSH directly into STM32CubeMX and STM32CubeIDE projects.

We currently support STM32Cube Expansion packs for wolfSSL and wolfSSH (our lightweight SSHv2/SCP/SFTP library). Soon we will be adding packs for wolfMQTT (our MQTT client implementation) and wolfTPM (our TPM 2.0 library).

For information on our wolfSSL Cube pack see: https://github.com/wolfSSL/wolfssl/blob/master/IDE/STM32Cube/README.md

For information on our wolfSSH Cube pack see: https://github.com/wolfSSL/wolfssh/blob/master/ide/STM32CUBE/README.md
