/**
|
|
* 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.
