16 MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a cryptographic
17 hash function based on a block cipher. This implementation is only available
18 with the legacy provider.
24 The MDC-2DES algorithm of using MDC-2 with the DES block cipher. It produces a
25 128-bit output from a given input.
31 Developers should be aware of the negative performance implications of
32 calling this function multiple times and should consider using
33 L<EVP_MD_fetch(3)> with L<EVP_MD-MDC2(7)> instead.
34 See L<crypto(7)/Performance> for further information.
38 These functions return a B<EVP_MD> structure that contains the
39 implementation of the message digest. See L<EVP_MD_meth_new(3)> for
40 details of the B<EVP_MD> structure.
44 ISO/IEC 10118-2:2000 Hash-Function 2, with DES as the underlying block cipher.
