Description:
This function initializes md4. This is automatically called by wc_Md4Hash.
Return Values:
0: Returned upon successfully initializing
Parameters:
md4 - pointer to the md4 structure to use for encryption
Example:

if ((ret = wc_InitMd4(md4)) != 0) {
WOLFSSL_MSG("wc_Initmd4 failed");
}
else {
wc_Md4Update(md4, data, len);
wc_Md4Final(md4, hash);
}

int wc_Md4Update(md4* md4, const byte* data, word32 len)
Description:
Can be called to continually hash the provided byte array of length len.
Return Values:
0: Returned upon successfully adding the data to the digest.
Parameters:
md4 - pointer to the md4 structure to use for encryption
data - the data to be hashed
