Java compatible cksum functionality

• Java

Is there any library / code in Java that computes the 32-bit CRC of the byte stream in a manner consistent with the cksum command in UNIX?

Solution

Jacksum： http://www.jonelo.de/java/jacksum/index.html

cksum         algorithm:   POSIX 1003.2 CRC algorithm
              length:      32 bits
              type:        crc
              since:       Jacksum 1.0.0
              comment:     - under BeOS    it is /bin/cksum
                           - under FreeBSD it is /usr/bin/cksum
                           - under HP-UX   it is /usr/bin/cksum and
                             /usr/bin/sum -p
                           - under IBM AIX it is /usr/bin/cksum
                           - under Linux   it is /usr/bin/cksum
