Introduction to the tool and how to use it
Online CRC checksum calculator supporting eight standard algorithms: CRC-8, CRC-8/MAXIM, CRC-16/ARC, CRC-16/CCITT-FALSE, CRC-16/XMODEM, CRC-16/MODBUS, CRC-32 and CRC-32C. Type one record per line and read it as UTF-8 text, a hex byte string or decimal bytes; fill in an expected value to verify every row, show the byte-by-byte steps, and export the result as CSV.
