About CRC-16

CRC-16 (Cyclic Redundancy Check) is a family of error-detecting codes that are used to detect accidental changes to raw data. Unlike cryptographic hash functions, CRC-16 is not designed for security but for efficient error detection in digital networks and storage.

CRC-16 algorithms use a 16-bit polynomial to generate a 16-bit checksum. There are several variants of CRC-16, each with different polynomials and initialization parameters. Common variants include CRC-16-CCITT, CRC-16-MODBUS, and CRC-16-USB.

Note:CRC-16 is not suitable for cryptographic purposes. It is primarily used for data integrity checks in communication protocols, storage systems, and file transfers.

Common Use Cases

  • Data transmission error detection
  • Communication protocols (e.g., Modbus, USB)
  • Storage systems and file transfers
  • Embedded systems and microcontrollers
  • Non-cryptographic integrity checks
