QT MD5 SHA1加密使用

MD5 hash

QString md5;

QString aStr="Nokia Qt";

QByteArraybb;

bb = QCryptographicHash::hash(aStr.toAscii(),QCryptographicHash::Md5 );

md5.append(bb.toHex());

sha1 hash

QString res="";    QByteArray string=aStr.toAscii();    QCryptographicHash *hash=new QCryptographicHash(QCryptographicHash::Sha1);    

hash->addData(string);    QByteArray sha1=hash->result();
