Constructor & Destructor Documentation

QxtHmac()

QxtHmac::QxtHmac

(

QCryptographicHash::Algorithm

algorithm

)

Constructs a QxtHmac object using the specified algorithm.

Member Function Documentation

addData() [1/2]

void QxtHmac::addData	(	const char *	data,
		int	length )

Adds the provided data to the message to be authenticated.

Here is the caller graph for this function:

addData() [2/2]

void QxtHmac::addData

(

const QByteArray &

data

)

Adds the provided data to the message to be authenticated.

Here is the call graph for this function:

hash()

QByteArray QxtHmac::hash ( const QByteArray & key, const QByteArray & data, Algorithm algorithm )

static

Returns the HMAC of the provided data using the specified key and hashing algorithm.

Here is the call graph for this function:

innerHash()

QByteArray QxtHmac::innerHash

(

)

const

Returns the inner hash of the HMAC function.

This hash can be stored in lieu of the shared secret on the authenticating side and used for verifying an HMAC code. When used in this manner, HMAC can be used to provide a form of secure password authentication. See the documentation above for details.

Here is the caller graph for this function:

reset()

void QxtHmac::reset

(

)

Resets the object.

Any data that had been processed using addData() will be discarded. The key, if set, will be preserved.

Here is the caller graph for this function:

result()

QByteArray QxtHmac::result

(

)

Returns the authentication code for the message.

Here is the call graph for this function:

Here is the caller graph for this function:

setKey()

void QxtHmac::setKey

(

QByteArray

key

)

Sets the shared secret key for the message authentication code.

Any data that had been processed using addData() will be discarded.

Here is the call graph for this function:

Here is the caller graph for this function:

verify() [1/2]

bool QxtHmac::verify ( const QByteArray & key, const QByteArray & hmac, const QByteArray & inner, Algorithm algorithm )

static

Verifies a HMAC against a known key and inner hash using the specified hashing algorithm.

Here is the call graph for this function:

verify() [2/2]

bool QxtHmac::verify

(

const QByteArray &

otherInner

)

Verifies the authentication code against a known inner hash.
