Class CksumFileDigester

java.lang.Object

net.nicoulaj.maven.plugins.checksum.digest.AbstractFileDigester

net.nicoulaj.maven.plugins.checksum.digest.CksumFileDigester

All Implemented Interfaces:

FileDigester

public class CksumFileDigester
extends AbstractFileDigester

Implementation of FileDigester for the POSIX 1003.2 CRC algorithm (32 bits).

The checksum calculated by this digester is consistent with Unix command cksum.

This implementation is based on Jacksum library implementation.

Since:

1.3
