These functions are an implementation of MDC2 with +DES. + +MDC2() computes the MDC2 message digest of the B<n> +bytes at B<d> and places it in B<md> (which must have space for +MDC2_DIGEST_LENGTH == 16 bytes of output). If B<md> is NULL, the digest +is placed in a static array. + +The following functions may be used if the message is not completely +stored in memory: + +MDC2_Init() initializes a B<MDC2_CTX> structure. + +MDC2_Update() can be called repeatedly with chunks of the message to +be hashed (B<len> bytes at B<data>). + +MDC2_Final() places the message digest in B<md>, which must have space +for MDC2_DIGEST_LENGTH == 16 bytes of output, and erases the B<MDC2_CTX>. + +Applications should use the higher level functions +L<EVP_DigestInit(3)|EVP_DigestInit(3)> etc. instead of calling the +hash functions directly. + +=head1 RETURN VALUES + +MDC2() returns a pointer to the hash value. + +MDC2_Init(), MDC2_Update() and MDC2_Final() return 1 for success, 0 otherwise. + +=head1 CONFORMING TO + +ISO/IEC 10118-2, with DES + +=head1 SEE ALSO + +L<sha(3)|sha(3)>, L<EVP_DigestInit(3)|EVP_DigestInit(3)> + +=head1 HISTORY + +MDC2(), MDC2_Init(), MDC2_Update() and MDC2_Final() are available since +SSLeay 0.8. + +=cut |
