 P: n/a so that script is server side? Am i right? And is it possible to decode that '0x6c,0x6f,0x63,0x61,0x74,0x69,0x6f,0x6e,0x20,0x3d ,0x20,0x27,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,0x77, signs? Regards D. Jul 23 '05 #4

 P: n/a Hey Dany, Those are hex numbers. Numbers with base 16, instead of 10 like we're used to. The 0x just means that they are hex numbers. An example for getting the value of the hex number 0x6c. Remove the 0x. The 6 is the most significant number, so we need to multiply that by 16. 6*16 = 96, then we have the C left, which is the least significant. We need to add that to the 96. C in hex is 12. 96+12 = 108. So 6c is decimal 108. This code is much used because one digit is exactly 4 bits, so two digits is exactly one byte. Easy for programmers to use once you understand it. The numbers we are used to are really exactly the same build up as hex numbers, except thats its base 10. Hex: 0x6C = 0x6*0x10 + 0xD (note that 0x10 != 10, but 0x10 = 16) Dec: 63 = 6 * 10 + 3 Some good examples: 0x0 = 0, 0x10 = 16, 0x20 = 32, 0xff = 255 (familiar numbers?) the value js_code contains the code. Its probably derives from the hex code in o. try alert(js_code) and you'll see the actual code. It seems to be some kind of protection for hiding the URL. Good luck, Vincent Dany wrote: hello, That script redirect to another site, but there is no o = '0x6c,0x6f,0x63,0x61,0x74,0x69,0x6f,0x6e,0x20,0x3d ,0x20,0x27,0x68,0x74,0x74, 0x70,0x3a,0x2f,0x2f,0x77,0x77,0x77,0x2e,0x74,0x72, 0x61,0x76,0x65,0x6c,0x77,0 x65,0x62,0x2e,0x70,0x6c,0x27,0x3b'; .................................. eval(js_code); What means these values? '0x6c,0x6f,0x63,0x61,0x74...., I am very novice but i know that javascript is not server side. How to debug this symbols and see the source of that code? Is that possible? Thank for answers Danny Jul 23 '05 #5
