URL: https://github.com/apache/nuttx/pull/19294
## Summary
Since already have support for SHA2-224, extend cryptodev/cryptosoft to
support HMAC version of SHA2-224.
## Impact
- User experience: No adaptation required. This fix extends existing
behavior.
- Build: No impact.
- Hardware: No impact.
- Documentation: Add mention of SHA2_224_HMAC crypto method.
- 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 followed by changing
configuration:
-- Enable CRYPTO_SW_AES
-- Disable CRYPTO_CRYPTODEV_HARDWARE
-- Enable CRYPTO_CRYPTODEV_SOTWARE_CRYPTO
-- Enable TESTING_CRYPTO_HMAC
Runtime testing:
Modified version of nuttx-apps/testing/drivers/crypto/hmac.c to add
SHA2_224_HMAC test results (generated by openssl) to run same HMAC testcase
data through SHA2_224_HMAC crypto method (PR coming in nuttx-apps repository to
submit these changes after this PR is merged).
