Detailed Description

This object calculates the HMAC signature for the input data.

Constructor & Destructor Documentation

cppcms::crypto::hmac::hmac	(	std::auto_ptr< message_digest >	digest,
		key const &	k
	)

Create hmac that uses given digest algorithm and a binary key - key

cppcms::crypto::hmac::hmac	(	std::string const &	name,
		key const &	k
	)

Create hmac that uses message digest algorithm called name and use a binary key - key

Member Function Documentation

void cppcms::crypto::hmac::append	(	void const *	ptr,
		size_t	size
	)

Add data for signing

unsigned cppcms::crypto::hmac::digest_size

(

)

const

Get the size of the signtature

void cppcms::crypto::hmac::readout

(

void *

ptr

)

Get the signature for all the data, after calling this function the state of the hmac is reset and it can be used for signing again

Note: provided buffer must be digest_size() bytes long.
