I'm considering using CRC-32 to checksum the contents of an encryption, and some literature suggests that such a checksum needs to be good at burst error detection. How does CRC-32 fare for burst error detection? How about (mostly-)isolated errors? -- John Kohl <jtkohl@ATHENA.MIT.EDU> or <jtkohl@MIT.EDU> Digital Equipment Corporation/Project Athena (The above opinions are MINE.
