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.

See also QByteArray::toHex().
