CRC32 for a unsigned array in C++

tlsk

Hi

I need to calculate the crc32 value for an unsigned array in C++.It goes like this..

unsigned char Myarray[16];

//Myarray contains hex value ... b525b4d0ad533acee2d6a214453a279e

Need to calculate the crc32 value for this Myarray[].
------------------------------------------------------------------------------------------
Have done something like this in java

bytes = md.digest( request.getBytes() );
// bytesToHex(bytes) -------> b525b4d0ad533acee2d6a214453a279e
CRC32 crc=new CRC32();
crc.reset();
crc.update(bytes);
checksum = crc.getValue(); // gives checksum as ---> 2422938937

-------------------------------------------------------------------------------------------
Need to get same value in C++ for the above mentioned Myarray[].

Thanks in advance. :)

If you can't be bothered to write the algorithm yourself (and TBH I wouldn't bother) then I suggest you search for an implementation on the web. I find Wikipedia a good place to start for this sort of thing.

Oh and CRC32 isn't very descriptive as there are at least 4 different 32 bit CRCs functions in common usage.
