The "CRC Calculator" displays interactively the CRC-16 and CRC-32 values for a specified string. (The CRC-32 values will match those computed by PKZIP.) Additional files, CRC16Dem and CRC32Dem, show how to create a command-line program to calculate CRC values. (A "C" command-line program is also available.)

Also see Item 13904, CRC FileCheck.

For additional details, as well as a number of URLs to other CRC information on the web, see the "Lab Report" at

- CRCDelphi.ZIP is for D3/D4/D5
- CRCDelphiOld.ZIP maintains compatibility with D2/D3 (see web site)
- CRCC.ZIP is a "C" command-line utility (with wildcards) (see web site)
