EVP_DigestInit_ex function

@RecordUse.new() @Native<Int Function(Pointer<EVP_MD_CTX>, Pointer<EVP_MD>, Pointer<ENGINE>)>(ffi.Pointer<EVP_MD_CTX>, ffi.Pointer<EVP_MD>, ffi.Pointer<ENGINE>)>(symbol: 'bssl_dart_EVP_DigestInit_ex') int EVP_DigestInit_ex(Pointer<EVP_MD_CTX> ctx, Pointer<EVP_MD> type, Pointer<ENGINE> engine)

EVP_DigestInit_ex configures ctx, whose memory must already have been initialised (e.g. with EVP_MD_CTX_init or EVP_MD_CTX_new), for a fresh hashing operation using type. It returns one on success and zero on allocation failure.

This function may be used to reconfigure an EVP_MD_CTX that was previously used for another operation.
