MDC2_Final() places the message digest in B<md>, which must have space
for MDC2_DIGEST_LENGTH == 16 bytes of output, and erases the B<MDC2_CTX>.
+Applications should use the higher level functions
+L<EVP_DigestInit(3)|EVP_DigestInit(3)> etc. instead of calling the
+hash functions directly.
+
=head1 RETURN VALUES
MDC2() returns a pointer to the hash value.
