Detailed Description
The QCryptographicHash class provides a way to generate cryptographic hashes.
QCryptographicHash can be used to generate cryptographic hashes of binary or text data.
Currently MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 are supported.

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.
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.
void QCryptographicHash::addData(const QByteArray & data)
This function overloads addData().
[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.
