Description

Details

MD5_CTX

typedef struct {
  uint32_t state[4];            /* state (ABCD) */
  uint32_t count[2];        	/* number of bits, modulo 2^64 (lsb first) */
  unsigned char buffer[64];     /* input buffer */
} MD5_CTX;

MD5Init ()

void        MD5Init                         (MD5_CTX *context);

Initializes MD5 context for the start of message digest computation.

context :

MD5 context to be initialized.

MD5Update ()

void        MD5Update                       (MD5_CTX *context,
                                             unsigned char *input,
                                             unsigned int inputLen);

MD5 block update operation. Continues an MD5 message-digest operation, processing another message block, and updating the context.

context :

MD5 context to be updated.

input :

pointer to data to be fed into MD5 algorithm.

inputLen :

size of input data in bytes.

MD5Final ()

void        MD5Final                        (unsigned char digest[16],
                                             MD5_CTX *context);

Ends an MD5 message-digest operation, writing the the message digest and zeroing the context. The context must be initialized with MD5Init() before being used for other MD5 checksum calculations.

digest :

16-byte buffer to write MD5 checksum.

context :

MD5 context to be finalized.
