wc_InitMd2()

void wc_InitMd2

(

Md2 *

)

This function initializes md2. This is automatically called by wc_Md2Hash.

Returns

0 Returned upon successfully initializing

Parameters

md2	pointer to the md2 structure to use for encryption

Example

md2 md2[1];
if ((ret = wc_InitMd2(md2)) != 0) {
   WOLFSSL_MSG("wc_Initmd2 failed");
}
else {
   wc_Md2Update(md2, data, len);
   wc_Md2Final(md2, hash);
}

wc_Md2Final()

void wc_Md2Final	(	Md2 *	md2,
		byte *	hash
	)

Finalizes hashing of data. Result is placed into hash.

Returns

0 Returned upon successfully finalizing.

Parameters

md2	pointer to the md2 structure to use for encryption
hash	Byte array to hold hash value.

Example

md2 md2[1];
byte data[] = { }; // Data to be hashed
word32 len = sizeof(data);
 
if ((ret = wc_InitMd2(md2)) != 0) {
   WOLFSSL_MSG("wc_Initmd2 failed");
}
else {
   wc_Md2Update(md2, data, len);
   wc_Md2Final(md2, hash);
}

wc_Md2Hash()

int wc_Md2Hash	(	const byte *	data,
		word32	len,
		byte *	hash
	)

Convenience function, handles all the hashing and places the result into hash.

Returns

0 Returned upon successfully hashing the data.

Memory_E memory error, unable to allocate memory. This is only possible with the small stack option enabled.

Parameters

data	the data to hash
len	the length of data
hash	Byte array to hold hash value.

Example

none

wc_Md2Update()

void wc_Md2Update	(	Md2 *	md2,
		const byte *	data,
		word32	len
	)

Can be called to continually hash the provided byte array of length len.

Returns

0 Returned upon successfully adding the data to the digest.

Parameters

md2	pointer to the md2 structure to use for encryption
data	the data to be hashed
len	length of data to be hashed

Example

md2 md2[1];
byte data[] = { }; // Data to be hashed
word32 len = sizeof(data);
 
if ((ret = wc_InitMd2(md2)) != 0) {
   WOLFSSL_MSG("wc_Initmd2 failed");
}
else {
   wc_Md2Update(md2, data, len);
   wc_Md2Final(md2, hash);
}
