Constructor & Destructor Documentation

QCryptographicHash::QCryptographicHash ( Algorithm  method)
explicit

Constructs an object that can be used to create a cryptographic hash from data using method.

QCryptographicHash::~QCryptographicHash ( )

Destroys the object.

Method Documentation

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)

Adds the data to the cryptographic hash.

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.

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.
