std::string Secure::hmac	(	std::string	msg,
		std::string	key,
		unsigned int	hashSize,
		void	hasherconst char *, const unsigned int, char *,
		unsigned int	blockSize
	)

Performs HMAC on msg with given key.

Uses given hasher function, requires hashSize to be set accordingly. Output is returned as hexadecimal alphanumeric string. The hasher function must be the "bin" version of the hasher to have a compatible function signature.

std::string Secure::hmac	(	const char *	msg,
		const unsigned int	msg_len,
		const char *	key,
		const unsigned int	key_len,
		unsigned int	hashSize,
		void	hasherconst char *, const unsigned int, char *,
		unsigned int	blockSize
	)

Performs HMAC on msg with given key.

Uses given hasher function, requires hashSize to be set accordingly. Output is returned as hexadecimal alphanumeric string. The hasher function must be the "bin" version of the hasher to have a compatible function signature.

std::string Secure::hmac_sha256	(	std::string	msg,
		std::string	key
	)

Convenience function that returns the hexadecimal alphanumeric HMAC-SHA256 of msg and key.

std::string Secure::hmac_sha256	(	const char *	msg,
		const unsigned int	msg_len,
		const char *	key,

	)

Convenience function that returns the hexadecimal alphanumeric HMAC-SHA256 of msg and key.

void Secure::hmac_sha256bin	(	const char *	msg,
		const unsigned int	msg_len,
		const char *	key,
		const unsigned int	key_len,
		char *	output
	)

Convenience function that sets output to the HMAC-SHA256 of msg and key in binary format.

Assumes at least 32 bytes are available for writing in output.

void Secure::hmacbin	(	const char *	msg,
		const unsigned int	msg_len,
		const char *	key,
		const unsigned int	key_len,
		unsigned int	hashSize,
		void	hasherconst char *, const unsigned int, char *,
		unsigned int	blockSize,
		char *	output
	)

Performs HMAC on msg with given key.

Uses given hasher function, requires hashSize to be set accordingly. Output is written in binary form to output, and assumes hashSize bytes are available to be written to. The hasher function must be the "bin" version of the hasher to have a compatible function signature.
