MBEDTLS_SHA1_C macro

\def MBEDTLS_SHA1_C Enable the SHA1 cryptographic hash algorithm. Module: library/sha1.c Caller: library/md.c library/psa_crypto_hash.c This module is required for TLS 1.2 depending on the handshake parameters, and for SHA1-signed certificates. \warning SHA-1 is considered a weak message digest and its use constitutes a security risk. If possible, we recommend avoiding dependencies on it, and considering stronger message digests instead.
