O gam builder , den tha sou allaksei hsn, tha sou tropopiisei aplos tis plirofories pou exeis se mia morfi pou ginete apodekti apo ta loaders. Den sou allazei kati stin karta, mono oi kriptografimenes grammes pou arxizoun apo 0201 to kanoun afto. Episis oi 0101 einai i katigoria emm entolon tis irdeto pou pernane stin karta.

Φίλε snakie σ' ευχαριστώ για την απάντηση. Επομένως το ερώτημα τώρα τίθεται ως εξής:

(1) Ποιο εργαλείο είναι πιο αξιόπιστο για τη δημιουργία gamma file αντί του gambuilder αλλά με έτοιμες μακροεντολές που να του περνάς απλά hsn και prov ? Γνωρίζεις κάποιο εσύ ή άλλος φίλος ?

(2) Αν η απάντηση στο (1) είναι αρνητική, τότε υπάρχει κάποιος οδηγός για τις γραμμές που συναντάς σ' ένα gamma file και την ερμηνεία τους καθώς επίσης πως φτιάχνεις μια τέτοια crypto γραμμή που να περιέχει καρφωτό hsn και (άλλη) για prov ?

Θα σου στείλω pm σχετικά

To create 0201 cmd ...
To create the 0201 command you need to make in this format. "020100" is special instruction to gamma to receive an update string next two bytes tells gamma which 3DES key to use from possible 16 keys. For example 02010003 tells gamma to use the forth key. Its forth because starts from 0. example: 020100020048F4347C4D8FC5E3A29A67C67DD205 .... here the gamma is told to use the third key because 020100002 (is 2 here starting from zero is 3rd key). Next is the length of the message. In this example is 48 (hex bytes). Next is the 8 byte DES cipher-block chained checksum (des-mac). This like digital signature. Next is 40 hex bytes of update message. Finally is the single byte CRC.


Re: To create 0201 cmd ...
Many people PM about how to create gamma update commands. Here is explain I put together for PMs

020100DKLNMMMMMMMMUSUL PAYLOAD CC
02 = Gamma update PDU
01 = CLA
00 = P1
DK = Index to 16byte Gamma update 3DES Key.
LN = Length of Message
MM = 8 Byte DES MAC
US = Update Selector (what to update)

For GSMK US = 01
For PMSK US = 02
For IV_PAD US = 03
For GMASK US = 04
For PMASK US = 05
For KEK US = 06
For COCO US = 08
For HSN US = 09
For ExiKey US = 0B
For AxiKey US = 0C
For ProviderID US = 10
For GroupKey US = 12
For ProductKey US = 13
For OS Erase US = 20
FOR OS Update US = 21

UL = Length of Update (for example for HSN UL = 03, for GMSK UL = 10, etc...)

PAYLOAD is the Update
CC = Message CRC or Checksum. Simply XOR message with 0x3F

OK to have multiple updates in one command.
Example:
020100DKLNMMMMMMMM0903HNHNHN0803COCOCO10 03PIPIPICC

This command will update HSN (HN), Coco (CO) and Provider ID (PI) in one go.

The DES MAC is calculated by prepending an 8 octet confounder to the plaintext, performing a DES CBC-mode encryption on the result using the key and an initialization vector of zero, taking the last block of the ciphertext, prepending the same confounder and encrypting the pair using DES in cipher-block-chaining (CBC) mode using a a variant of the key, where the variant is computed by eXclusive-ORing the key

The message after LN is encrypted using the Triple DES mode CBC until the CC using 16 byte key in index DK

Και γω παλεύω τον τελευταίο καιρό να μάθω να κάνω cmd 0201 ...

Έφτασα σε σημείο να κάνω την decrypted γραμμή που χρειάζεται για να αλλάζω HSN ή provider ...
π.χ. για HSN 079AB1 (τυχαίο)

8912E1B08086646F15079C51D35FEC9A73A65170 0B10E11277 A94DFBAA9B86732C6AB8C590B70C10E62E1ADE4E 9AB245606733E5DBB1188A0903079AB10D0118


Padding Byte (UC>89) = 12 (This instructs the gamma to ignore the next 12 bytes)
ExiKey (UC->0B) = E11277A94DFBAA9B86732C6AB8C590B7
AxiKey (UC->0C) = E62E1ADE4E9AB245606733E5DBB1188A
abHex (UC->09) = 079AB1


Το πρόβλημά μου είναι η κωδικοποίηση και φυσικά η έλειψη γνώσης των 16 triple des keys ...

Δεν κατάλαβα πως έκανες το πρόγραμμα χωρίς αυτά τα κλειδιά ...

Δυστυχώς δεν έχω γνώσεις προγραμματισμού για να πάω παρακάτω ...
