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

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.
