/**
* Hash information that's independent from the crypto implementation.
*
* This can be used by:
* - code based on PSA
* - code based on the legacy API
* - code based on either of them depending on MBEDTLS_USE_PSA_CRYPTO
* - code based on either of them depending on what's available
*
* Note: this internal module will go away when everything becomes based on
* PSA Crypto; it is a helper for the transition while hash algorithms are
* still represented using mbedtls_md_type_t in most places even when PSA is
* used for the actual crypto computations.
