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, and SHA-1 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.
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().

QCA
QCryptographicHash provides an implementation of some cryptographic hashes (MD4, MD5, SHA1).
If for some reason you need to use other hashing algorithms (SHA256, SHA512), or, in general, to encrypt and decrypt data (f.i. by using AES, Blowfish, etc.), you can use QCA (Qt Cryptography Architecture).
