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().

bool QCryptographicHash::addData(QIODevice *device)

Reads the data from the open QIODevice device until it ends and hashes it. Returns true if reading was successful.

This function was introduced in Qt 5.0.

[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.
