Reverse Engineering Team Board - Crypkey : How to get sitekey using cKInfo

This is what I've learn from various website on how to get the sitekey for a software that protected with Crypkey.

1. Get the sitecode from the Authorization box.
2. By using ckinfo, check the code. See the example below.

HTML Code:

C:\Documents and Settings\Test\Desktop>ckinfo.exe /sitecode D182 C81C 5C9F 02A270

CrypKey Copy Protection Information v1.12

Parsing Code    - D182 C81C 5C9F 02A2 70

Decrypting Code - 07BE 362C 0583 4CAB 55

Formatting Code :

                            BE 36 2C05 834C AB55

                            +¦ +¦ ¦--+ ¦--+ ¦--+

  Site Code Id - 0x3E -------¦  ¦ ¦    ¦    +--------------- Code CRC - 0xAB55

  Allow Add Licence? - Yes --+  ¦ ¦    ¦-------- User Key Hash (Seed) - 0x4C83

  Allow Easy Licence? - No -----¦ ¦    +--------- Drive Serial Number - unused

  CrypKey Libraries - v5.4 -----+ ¦- Account Number - 300

                                  ¦- Application Id - 1

                                  +- Company Number - 7956300

3. To generate the sitekey, we must find the masterkey and userkey. These keys can be found in the exe or dll of the target s/w. This can be done using Ollydbg and etc.
4. In the Ollydbg, use Ultra String Reference->Find ASCII. Usually these keys are in plain text. See example below.

5. Then check those keys with ckinfo. See example below.

Master key

HTML Code:

C:\Documents and Settings\Test\Desktop>ckinfo.exe /masterkey EA9F 55C4 D8FE 2252 EA98 1B43 EAD1 C446 5D94 C446 F33D

User key

                 ¦--- User Key Hash (1) - 0x55

                 +--- User Key Hash (2) - 0xF815

6. The purpose for the checking is to find the information that needed to create a valid site key.
7. After that by using ckinfo again, we can generate a valid key for the software. See example below.

HTML Code:

C:\Documents and Settings\Test\Desktop>ckinfo.exe /createkey site

8. The valid site key is the Encrypting Key. Copy and paste it to the Authorization box and good luck.

Hope this will help others that still finding the right way to generate site key for s/w using Crypkey protection.
If there is any mistake, hope others can give a guide. I'm still learning on this stuff.
