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.
- 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) 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.
