QCryptoHash

The QCryptoHash class provides a way to generate cryptographic hashes. It can be used to generate cryptographic hashes of binary or text data.

Currently Tiger-192, RipeMD-160 and Whirlpool are supported.

Member Function Documentation

QCryptoHash::QCryptoHash( Algorithm method )

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

QCryptoHash::~QCryptoHash()

Destroys the object.

void QCryptoHash::reset()

Resets the object.

void QCryptoHash::addData( const char *data, int length )

Adds the first length chars of data to the cryptographic hash.

void QCryptoHash::addData( const QByteArray &data )

Adds the bytes of data to the cryptographic hash.

bool QCryptoHash::addData( QIODevice *device )

Reads the data from the open QIODevice device until it ends and hashes it.

Returns true if reading was successful.

QByteArray QCryptoHash::result() const

Returns the final hash value.

[static] QByteArray QCryptoHash::hash( const QByteArray &data, Algorithm method )

Returns the hash of data using method.
