(1) image processing is expensive compared to a straight checksum. (2) everybody doing the test has to do it exactly the same way, or there is no hope of getting a shared checksum that will match other peoples' traffic. (3) is the same image guaranteed to shrink the same way every time? -- John Hardin KA7OHZ ICQ#15735746 http://www.impsec.org/~jhardin/ [EMAIL PROTECTED] FALaholic #11174 pgpk -a [EMAIL PROTECTED] key: 0xB8732E79 - 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- Look at the people at the top of both efforts. Linus Torvalds is a university graduate with a CS degree. Bill Gates is a university dropout who bragged about dumpster-diving and using other peoples' garbage code as the basis for his code. Maybe that has something to do with the difference in quality/security between Linux and Windows. -- anytwofiveelevenis on Y!
