=pod =head1 NAME EVP_mdc2 - MDC-2 For EVP =head1 SYNOPSIS #include const EVP_MD *EVP_mdc2(void); =head1 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. =over 4 =item 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. =back =head1 RETURN VALUES These functions return a B structure that contains the implementation of the message digest. See L for details of the B structure. =head1 CONFORMING TO ISO/IEC 10118-2:2000 Hash-Function 2, with DES as the underlying block cipher. =head1 SEE ALSO L, L, L =head1 COPYRIGHT Copyright 2017-2022 The OpenSSL Project Authors.
