Hanno Becker a5cedbcd3f Introduce MD handle type ... As has been previously done for ciphersuites, this commit introduces a zero-cost abstraction layer around the type mbedtls_md_info const * whose valid values represent implementations of message digest algorithms. Access to a particular digest implementation can be requested by name or digest ID through the API mbedtls_md_info_from_xxx(), which either returns a valid implementation or NULL, representing failure. This commit replaces such uses of `mbedtls_md_info const *` by an abstract type `mbedtls_md_handle_t` whose valid values represent digest implementations, and which has a designated invalid value MBEDTLS_MD_INVALID_HANDLE. The purpose of this abstraction layer is to pave the way for builds which support precisely one digest algorithm. In this case, mbedtls_md_handle_t can be implemented as a two-valued type, with one value representing the invalid handle, and the unique valid value representing the unique enabled digest.		2019-09-09 09:45:57 +01:00
