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.
MD2, MD4, and MD5 are recommended only for compatibility with existing applications. In new applications, SHA-256(or greater) should be preferred.
All routines return 1 upon success and NULL upon failure, except
for the one-shot routines ( CC_MD2
() , etc.), which
return the pointer passed in via the md parameter.

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.
