WebCRC24 Hash is a hash function that uses the CRC algorithm to generate a 24-bit output. The CRC algorithm is a type of checksum that detects errors in digital data transmission, such as corrupted or altered data. The CRC algorithm works by dividing the input data into a series of equal-length chunks, performing a series of bitwise operations ... WebSep 30, 2024 · As a type of checksum, the CRC produces a fixed-length data set based on the build of a file or larger data set.
