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().
QByteArray QCryptographicHash::hash ( const QByteArray & data, Algorithm method ) [static]
Returns the hash of data using method.
void QCryptographicHash::reset ()
Resets the object.
QByteArray QCryptographicHash::result () const
Returns the final hash value.
