5 Feb 2019 Cyclic Redundancy Check (CRC)Cyclic Redundancy Check (CRC) is a block code that was invented by W. Wesley Peterson in 1961.

This number is 0x2144DF1C for CRC32 and 0x48674BC7 for CRC32C. CRC32 is a checksum algorithm that detects if a message was not modified. It is widely used: for example, sending packages through the Ethernet network implies calculating of the checksum.

Crc32 algorithm

Note: The concepts behind the various CRC32 algorithm are not my original work - I only gathered them in one place. I assume a little-endian architecture (Intel's x86 and x64 CPU default byte ordering) and ints to be 32 bits wide (replace unsigned int by uint32_t if you use GCC64/Unix). Simple CRC32 C-code. Here is a simple implementation of the commonly used CRC32 checksum using the reverse polynomial 0xEDB88320. The algorithm is consistent with setting of all bits in the initial CRC, along with negation of the bit pattern of the final running CRC. NullFX CRC is a small set of CRC utilities (crc8, crc16, and crc32) written in C# and released under the MIT License HashAlgorithms . Hash algorithm implementations for .NET, including CRC (CRC32 and CRC16). All hash algorithms support streaming (hashing a block at a time) and have full support for Span to prevent unnecessary memory allocation.

This section uses pseudo code to explain how to generate the 32-bit CRC value stored in the CRC field of the COMPRESSED_BLOCK_HEADER structure. Define CalculateCRC32 as Function With Parameters ( buffer as unsigned char [] length as unsigned integer ) Begin Define crc as unsigned integer Define index as integer crc = 0xFFFFFFFF index := 0 While (index < length) Begin crc := crc32_table [ (crc AND 0xFF) XOR buffer [index]] ^ (crc / 256) index := index + 1 End return crc XOR
