[PD] CRC-Checksum

[David Schaffer]

Hi, I'm working on a .png glitcher abstraction that recquires me to recalculate the  4-byte CRC (Cyclic Redundancy Check) for each chunk I modify. I 'm very new to this and I was wondering if anyone of you guys had ever made a pd implementation of that algorithm. Thank you!
