NAME¶

EVP_mdc2 - MDC-2 For EVP

SYNOPSIS¶

 #include <openssl/evp.h>
 const EVP_MD *EVP_mdc2(void);

DESCRIPTION¶

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.

RETURN VALUES¶

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.

CONFORMING TO¶

ISO/IEC 10118-2:2000 Hash-Function 2, with DES as the underlying block cipher.
