Data Structures
struct	Poly1305

Typedefs
typedef struct Poly1305	Poly1305

Functions
WOLFSSL_API int	wc_Poly1305SetKey (Poly1305 *poly1305, const byte *key, word32 kySz)
	This function sets the key for a Poly1305 context structure, initializing it for hashing. Note: A new key should be set after generating a message hash with wc_Poly1305Final to ensure security.
WOLFSSL_API int	wc_Poly1305Update (Poly1305 *poly1305, const byte *, word32)
	This function updates the message to hash with the Poly1305 structure.
WOLFSSL_API int	wc_Poly1305Final (Poly1305 *poly1305, byte *tag)
	This function calculates the hash of the input messages and stores the result in mac. After this is called, the key should be reset.
WOLFSSL_API int	wc_Poly1305_Pad (Poly1305 *ctx, word32 lenToPad)
WOLFSSL_API int	wc_Poly1305_EncodeSizes (Poly1305 *ctx, word32 aadSz, word32 dataSz)
WOLFSSL_API int	wc_Poly1305_MAC (Poly1305 *ctx, byte *additional, word32 addSz, byte *input, word32 sz, byte *tag, word32 tagSz)
	Takes in an initialized Poly1305 struct that has a key loaded and creates a MAC (tag) using recent TLS AEAD padding scheme.
void	poly1305_block (Poly1305 *ctx, const unsigned char *m)
void	poly1305_blocks (Poly1305 *ctx, const unsigned char *m, size_t bytes)
