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: + +RIPEMD160_Init() initializes a B<RIPEMD160_CTX> structure. + +RIPEMD160_Update() can be called repeatedly with chunks of the message to +be hashed (B<len> bytes at B<data>). + +RIPEMD160_Final() places the message digest in B<md>, which must have +space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases +the B<RIPEMD160_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 + +RIPEMD160() returns a pointer to the hash value. + +RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for +success, 0 otherwise. + +=head1 CONFORMING TO + +ISO/IEC 10118-3 (draft) (??) + +=head1 SEE ALSO + +L<sha(3)|sha(3)>, L<hmac(3)|hmac(3)>, L<EVP_DigestInit(3)|EVP_DigestInit(3)> + +=head1 HISTORY + +RIPEMD160(), RIPEMD160_Init(), RIPEMD160_Update() and +RIPEMD160_Final() are available since SSLeay 0.9.0. + +=cut |
