EVP_md2(3)                          OpenSSL                         EVP_md2(3)




NAME

       EVP_md2 - MD2 For EVP


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/evp.h>

        const EVP_MD *EVP_md2(void);


DESCRIPTION

       MD2 is a cryptographic hash function standardized in RFC 1319 and
       designed by Ronald Rivest. This implementation is only available with
       the legacy provider.

       EVP_md2()
           The MD2 algorithm which produces a 128-bit output from a given
           input.


NOTES

       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-MD2(7) instead.  See "Performance" in
       crypto(7) for further information.


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

       IETF RFC 1319.
