QtCryptoHash

QtCryptoHash is a Qt C++ library providing a way to calculate some of the cryptographic hashes not supported by the QCryptographicHash class from the Qt library.

Features

• Supports Tiger-192, RipeMD-160 and Whirlpool algorithms
• Simple interface, identical to the QCryptographicHash class, but renamed QCryptoHash
• Works with Qt 5.x
• Supports MSVC, MinGW, GCC and Clang

Basic Usage

String Hash Calculation

#include "qcryptohash.hpp"
...
QByteArray stringHash = QCryptoHash::hash( "abc", QCryptoHash::TIGER );
qInfo() << stringHash.toHex(); //f258c1e88414ab2a527ab541ffc5b8bf935f7b951c132951

File Hash Calculation

#include "qcryptohash.hpp"
...
QFile file( filename );
if ( file.open( QFile::ReadOnly ) ) {
	QCryptoHash ripemdHash( QCryptoHash::RMD160 );
	while( !file.atEnd() ){
		ripemdHash.addData( file.read( 8192 ) );
	}
	QByteArray fileHash = ripemdHash.result();	
	qInfo() << fileHash.toHex(); //RipeMD hash of 'filename' file content
}

Dependencies

QtCryptoHash needs only QtCore library to be linked to the program.
