int wc_SipHash(const unsigned char *key, const unsigned char *in, word32 inSz, unsigned char *out, unsigned char outSz)
This function one-shots the data using SipHash to calculate a MAC based on the key.
int wc_InitSipHash(SipHash *siphash, const unsigned char *key, unsigned char outSz)
This function initializes SipHash with a key for a MAC size.
int wc_SipHashUpdate(SipHash *siphash, const unsigned char *in, word32 inSz)
Can be called to continually hash the provided byte array of length len.
int wc_SipHashFinal(SipHash *siphash, unsigned char *out, unsigned char outSz)
Finalizes MACing of data. Result is placed into out.
