CRC32 file checksum calculator tool is a free online tool that can be used to calculate the CRC32 checksum of any file. Just upload the file and click on the calculate button. The checksum will be calculated and displayed in the output box.
CRC32 is a checksum algorithm that is used to detect errors in data that has been transmitted.
The algorithm is based on the fact that when two pieces of data are XORed together, the resulting data will have a certain number of bits set to 1. The number of bits set to 1 is called the Hamming weight. The CRC32 algorithm uses the Hamming weight to calculate a checksum for a block of data.
The CRC32 checksum is a 32-bit number.
