HTTP registry: UNIXcksum
The algorithm computed by the UNIX ``cksum'' command, as defined by the Single UNIX Specification, Version 2. The output of this algorithm is an ASCII digit string representing the 32-bit CRC, which is the first word of the output of the UNIX ``cksum'' command.
Integrity registry values define algorithms or message metadata used to detect alteration of HTTP content or representations. UNIXcksum is registered in HTTP Digest Algorithm Values.
