[eren-terzioglu]

Summary

Add missing SHA features for Espressif devices

• boards/xtensa/esp32[-s2|-s3]: Add SHA accelerator features

Add SHA accelerator board features for esp32[-s2|-s3]

• boards/risc-v/esp32[-c3|c6|-h2]: Add SHA accelerator features

Add SHA accelerator board features for esp32[-c3|-c6|-h2]

• arch/xtensa/espressif: Add SHA accelerator features

Add SHA accelerator features for esp32[-s2|-s3]

• arch/risc-v/espressif: Add SHA accelerator features

Add SHA accelerator features for esp32[-c3|-c6|-h2]

Impact

Impact on user: Yes, SHA accelerator can be used without HMAC

Impact on build: No

Impact on hardware: No

Impact on documentation: No

Impact on security: No

Impact on compatibility: No

Testing

esp32s3-devkit:crypto and esp32c6-devkitc:crypto configs used with TESTING_CRYPTO_HASH option enabled. Due to the test structure unrelated tests closed by commenting (md5 and sha512 for esp32c6; md5 for esp32s3)

Building

make -j distclean && ./tools/configure.sh esp32c6-devkitc:crypto && kconfig-tweak -e CONFIG_TESTING_CRYPTO_HASH && make -j && make download ESPTOOL_PORT=/dev/ttyUSB0 ESPTOOL_BAUD=921600 ESPTOOL_BINDIR=./

Running

hash command run

Results

For esp32c6:

...
nsh> hash
hash sha1 success
hash sha1 success
hash sha1 success
hash sha256 success
hash sha256 success
hash sha256 success
nsh>

For esp32s3:

hash sha1 success
hash sha1 success
hash sha256 success
hash sha256 success
hash sha256 success
hash sha512 success
hash sha512 success
hash sha512 success
