If B 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: + +MD2_Init() initializes a B structure. + +MD2_Update() can be called repeatedly with chunks of the message to +be hashed (B bytes at B). + +MD2_Final() places the message digest in B, which must have space +for MD2_DIGEST_LENGTH == 16 bytes of output, and erases the B. + +MD4_Init(), MD4_Update(), MD4_Final(), MD5_Init(), MD5_Update(), and +MD5_Final() are analogous using an B and B structure. + +Applications should use the higher level functions +L +etc. instead of calling the hash functions directly. + +=head1 NOTE + +MD2, MD4, and MD5 are recommended only for compatibility with existing +applications.
