Describe the bug

With MBEDTLS (2.28.1) library when you try to handshake a connection is computed a SHA256. Ouput buffer of the caam peripheral is not aligned to 32bit.

When function names "ssl_prepare_server_key_exchange" is called "unsigned char hash[MBEDTLS_MD_MAX_SIZE]" is allocated on the stack, but is not aligned. (file ssl_srv.c, row number 3519.)

Hi @GiulioDallaVecchia, I could not reproduce this issue on my end. Could you please provide additional information on your environment, such as the used board, compiler / IDE and any specific compiler settings you are using?
