I was told that I have to take a 56 bit hex number (MEID) and convert it to a 32 bit hex number (pESN). The end result should look like this.. * The upper 8 bits of pseudo-ESN shall be set to 0x80. * The lower 24 bits of pseudo-ESN shall be the 24 least significant bits of the SHA-1 digest of the MEID.
So the pESN should be 80 XX XX XX. An example is this.. Example: if the 56-bit MEID is (hexadecimal) FF 00 00 01 12 34 56, the pseudo-ESN is (hexadecimal) 80 07 37 E1. I can't get this to compute.. I downloaded the a tag from cflib.. http://www.cflib.org/udf.cfm?ID=34 and it returns the digest of when applying the SHA-1 algorithm to "FF000001123456": 9894AF3B86038B3E14D7313C726CCDDD9319124E I've tried using InputBaseN and FormatBaseN and I'm having no luck. Given message=FF000001123456 The SHA-1 message digest is: 9894AF3B86038B3E14D7313C726CCDDD9319124E So I need to get the 24 least significant bits and convert it to hex and some how it'll equal 07 37 E1. I'm taking the last 8 digits from the digest and playing around with that "9319124E" Given message=FF000001123456 The SHA-1 message digest is: 9319124E InputBaseN(sha,16): -1827073458 Right 24 (binary): 000110010001001001001110 <- that should be the least 24 significant bits To Number: 1643086 <- using inputbasen To Hex: 19124e <- using formatbasen and that hex doesnt equal 0737E1 What am I missing here? -- Auxilium meum a Domino ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Discover CFTicket - The leading ColdFusion Help Desk and Trouble Ticket application http://www.houseoffusion.com/banners/view.cfm?bannerid=48 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:212172 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
