Java兼容的cksum功能 [英] Java compatible cksum function

问题描述

Java中是否有任何库/代码以与unix中的cksum命令一致的方式计算字节流的32位CRC？

Is there any library/code in Java to calculate the 32-bit CRC of a stream of bytes in a way thats consistent with the cksum command in unix ?

推荐答案

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 

它是开源的。
