I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. Feb 12, 2022 ... Non-cryptographic hash functions are pretty prone to collisions when applied to real data, so I think you should also use a cryptographic hash function here.
