Set parameters of qChecksum
-
Hi Folks,
I need to generate checksum for an array of data. Its stored in QByteArray, and as I googled, I found the qChecksum method, but I couldnot figure out, how should I set the parameters for CRC, like:
- applied algorithm
- seed
- polinome
- etc...
can anybody explain me, how I can use this method, or is there any alternative Qt solution for CRC generation?
Regards,
Norbert

There are no more Parameters to set in qChecksum see Documentation:
quint16 qChecksum(const char * data, uint len)
Returns the CRC-16 checksum of the first len bytes of data.
The checksum is independent of the byte order (endianness).
**Note: This function is a 16-bit cache conserving (16 entry table) implementation of the CRC-16-CCITT algorithm.
**But maybe you can use QCryptographicHash Class
Currently MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 are supported.

Hi,
I read the description of the method, but you can check for example this bug report:
https://bugreports.qt.io/browse/QTBUG-8595In order to generate CRC, you need (you can set) to adjust more parameter as the input data.
