NAME

6       EVP_mdc2 - MDC-2 For EVP
7

SYNOPSIS

9        #include <openssl/evp.h>
10
11        const EVP_MD *EVP_mdc2(void);
12

DESCRIPTION

14       MDC-2 (Modification Detection Code 2 or Meyer-Schilling) is a
15       cryptographic hash function based on a block cipher. This
16       implementation is only available with the legacy provider.
17
18       EVP_mdc2()
19           The MDC-2DES algorithm of using MDC-2 with the DES block cipher. It
20           produces a 128-bit output from a given input.
21

NOTES

23       Developers should be aware of the negative performance implications of
24       calling this function multiple times and should consider using
25       EVP_MD_fetch(3) instead.  See "Performance" in crypto(7) for further
26       information.
27

RETURN VALUES

29       These functions return a EVP_MD structure that contains the
30       implementation of the message digest. See EVP_MD_meth_new(3) for
31       details of the EVP_MD structure.
32

CONFORMING TO

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