Member Function Documentation
QCryptographicHash::QCryptographicHash(Algorithm method)
Constructs an object that can be used to create a cryptographic hash from data using method.
QCryptographicHash::~QCryptographicHash()
Destroys the object.
void QCryptographicHash::addData(const char * data, int length)
Adds the first length chars of data to the cryptographic hash.
void QCryptographicHash::addData(const QByteArray & data)
This function overloads addData().
[static] QByteArray QCryptographicHash::hash(const QByteArray & data, Algorithm method)
Returns the hash of data using method.
void QCryptographicHash::reset()
Resets the object.
QByteArray QCryptographicHash::result() const
Returns the final hash value.
