griffo-io / crc32 Goto Github PK

I think there is some problem in calculating the crc. It's givivng different values from the online calculators.

I checked taking crc of a sing byte 0x03 and using the polynomial 0x04C11DB7u and seed 0xffffffffu. The expected output is 0x4B0BBE37, but I'm getting 4186413953 which is 0xF9879B81.

This is my code:

protected uint calculateCRC(byte[] array)
        {
            uint crc = Crc32Algorithm.Compute(0x04C11DB7u, 0xffffffffu, array);
            return crc;
        }

I'm using

.Net core 2.1
