Summary

Extend stm32h7 HW crypto to support MD5, SHA1, SHA2-224, SHA2-256 accelerations along with their HMAC variants.

Impact

  • User experience: No adaptation required. This fix extends existing behavior.
  • Build: No impact.
  • Hardware: No impact.
  • Documentation: No impact..
  • Security: No impact.
  • Compatibility: Backward compatible - adds functionality.

Testing

Build Host:

  • OS: Ubuntu 24.04.4 LTS
  • Compiler: arm-none-eabi-gcc 13.2.1

Target:

  • Architecture: ARM (STM32H753ZI)
  • Board: Nucleo-h753zi
  • Configuration: nucleo-h753zi:crypto configuration

Runtime testing:

Booted, ran crc32, hsash, hmac, aescbc, and aesctr crypto test utilities and verified HW acceleration is used.
