SYNOPSIS
#include <CommonCrypto/CommonDigest.h> extern int CC_MD2_Init(CC_MD2_CTX *c); extern int CC_MD2_Update(CC_MD2_CTX *c, const void *data, CC_LONG len); extern int CC_MD2_Final(unsigned char *md, CC_MD2_CTX *c); extern unsigned char * CC_MD2(const void *data, CC_LONG len, unsigned char *md); extern int CC_MD4_Init(CC_MD4_CTX *c); extern int CC_MD4_Update(CC_MD4_CTX *c, const void *data, CC_LONG len); extern int CC_MD4_Final(unsigned char *md, CC_MD4_CTX *c); extern unsigned char * CC_MD4(const void *data, CC_LONG len, unsigned char *md); extern int CC_MD5_Init(CC_MD5_CTX *c); extern int CC_MD5_Update(CC_MD5_CTX *c, const void *data, CC_LONG len); extern int CC_MD5_Final(unsigned char *md, CC_MD5_CTX *c); extern unsigned char * CC_MD5(const void *data, CC_LONG len, unsigned char *md);
DESCRIPTION
The following functions are used to produce an hash from data: CC_MD2_Init() initializes a CC_MD2_CTX structure. CC_MD2_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data). CC_MD2_Final() places the MD2 message digest in md, which must have space for CC_MD2_DIGEST_LENGTH == 16 bytes of output, and erases the CC_MD2_CTX. CC_MD2() computes the MD2 message digest of the len bytes at data and places it in md (which must have space for CC_MD2_DIGEST_LENGTH == 16 bytes of output). It returns the md pointer. CC_MD4_Init(), CC_MD4_Update(), CC_MD4_Final(), CC_MD4(), CC_MD5_Init(), CC_MD5_Update(), CC_MD5_Final(), and CC_MD5() are analogous using an CC_MD4_CTX and CC_MD5_CTX structure.
NOTE
MD2, MD4, and MD5 are recommended only for compatibility with existing applications. In new applications, SHA-256(or greater) should be pre- ferred.
RETURN VALUES
All routines return 1 except for the one-shot routines ( CC_MD2() , etc.), which return the pointer passed in via the md parameter.

HISTORY
These functions are available in OS X 10.4 and later. These functions provide similar functionality to the routines found in OpenSSL 0.9.6 and may use the same implementation.
