EVP_mdc2 - MDC-2 For EVP
#include <openssl/evp.h>
const EVP_MD *EVP_mdc2(void);
MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a cryptographic hash
function based on a block cipher. This implementation is only available with
the legacy provider.
- EVP_mdc2()
- The MDC-2DES algorithm of using MDC-2 with the DES block
cipher. It produces a 128-bit output from a given input.
Developers should be aware of the negative performance implications of calling
this function multiple times and should consider using
EVP_MD_fetch(3)
with
EVP_MD-MDC2(7) instead. See "Performance" in
crypto(7) for further information.
These functions return a
EVP_MD structure that contains the
implementation of the message digest. See
EVP_MD_meth_new(3) for
details of the
EVP_MD structure.
ISO/IEC 10118-2:2000 Hash-Function 2, with DES as the underlying block cipher.
