Can someone please tell which CRC polynomial is used in the MacBinary II header, preferably with some sample code calculating it. The documentation I have makes no mention of how the CRC is found. I'm using the MacBinary format in my DES encryption program, to pack the file into a single stream before encrypting on the fly. It works quite nicely apart from the aforementioned CRC. I can encrypt on the Mac, download to a Unix beasty, decrypt, and get a MacBinary file that is byte for byte identical to the original which was downloaded directly using Freeterm's MacBinary mode (apart from the ***expletive deleted*** CRC). So, any help would be much appreciated. Thanks Lawrie. ---- Mr. Lawrie Brown, Phone ISD: +61 62 688170 Fax: +61 62 688581 Dept.
