Online implementation of CRC-32 (Cyclic Redundancy Check) algorithm. Easily calculate CRC32 checksum and find related resources.

GitHub Gist: instantly share code, notes, and snippets. Many protocols, like Ethernet and GZIP archives, append a so-called CRC hash to their data streams which has a few weaknesses regarding uniqueness (sometimes data modifications remain undetected) but is absolutely great when it comes to compactness (CRC32: 32 bits) and efficiency.

The implementation here seems nice, but the only thing it says about the license is "source code", which isn't good enough. I'd prefer non LGPL so I don't have to fool around with a DLL (my app is closed source). 102 rows 2009-05-26 How do I calculate the CRC32 (Cyclic Redundancy Checksum) of a string in .NET? LibCRC is an MIT licensed library written in C containing various checksum algorithms.

Polynomials over GF(2) are represented in binary, one bit per coefficient, with the lowest powers in the most significant bit. Then adding polynomials A CRC is a powerful type of checksum that is able to detect corruption of data that is stored in and/or transmitted between computers. Generally speaking, CRCs are most efficiently calculated in dedicated hardware.

CRC CRC32 is a checksum/hashing algorithm that is very commonly used in kernels and for Internet checksums. It is very similar to the MD5 checksum algorithm. Calculate CRC-8, CRC-16, CRC-32, MD5 checksums online for free 123456789 Input type: ASCII Hex Output type: HEX DEC OCT BIN Show processed data (HEX) LibCRC is an MIT licensed library written in C containing various checksum algorithms. These include the most common CRC implementations but also other checksums like the NMEA checksum used by marine equipment. Previously these routines could be downloaded from the site www.lammertbies.nl. Those sources have been merged with further unpublished /* This is the basic CRC-32 calculation with some optimization but no table lookup.
