Hi, I never decode OBJECT ID before, so please help me with the following questions.
> itu-t (0) recommendation (0) h (8) 245 version (0) 2 > 1) 40 * 0 + 0 = 0 ===> Why 40? where 40 comes from? and why only 1 byte for both "itu-t (0) recommendation (0)"? why not 2 bytes? 1 byte (0) for itu-t and other byte (0) for recommendation? > 2) 8 > 3+4) 245 = 11110101B => 1 0000001 0 1110101 = F1 75 ===> How "11110101B" is converted to "1 0000001 0 1110101"? > 5) 0 > 6) 2 Thanks!

Is there a significance for the deviation? regards, Sathya Narayanan S RPG Cellular Services Limited GSM : +91 98410 48051 > -----Original Message----- > From: Bernd Kunze > Sent: Monday, November 05, 2001 9:15 PM > To: '[EMAIL PROTECTED]' > Subject: RE: [ASN.1] itu-t (0) recommendation (0) h (8) 245 version > (0) 2 > > Hi, > > itu-t (0) recommendation (0) h (8) 245 version (0) 2 > > 1) 40 * 0 + 0 = 0 > 2) 8 > 3+4) 245 = 11110101B => 1 0000001 0 1110101 = F1 75 > 5) 0 > 6) 2 > > => 00 08 F1 75 00 02 > > Bernd
