How to get sha1 hash

[lyuts]

Hi, guys. I need you help.

I'm trying to obtain a sha1 hash. I use QCryptographicHash for this.

QCryptographicHash hash(QCryptographicHash::Sha1);
hash.addData("123", 3);

QCryptographicHash hash(QCryptographicHash::Sha1);
hash.addData("123", 3);

To copy to clipboard, switch view to plain text mode 

But I get something like this
"$6rJ╟)щъa4тБ(\еEY├"
instead of
"40bd001563085fc35165329ea1ff5c5ecbdbbeef".
What am I doing wrong?

Thanks.

There's an example in our wiki: [WIKI]Cryptography[/WIKI]. Use QByteArray::toHex() to get a hexadecimal presentation of the hash.
