Greetings:

I have an CrypKey Protected App in my hands. Unfortunately, that is *7* day trial and in my over curiosity, I burnt all 7 .

Is there any way I can re-enable the trial without HD format. I'm sure there is. I searched the board but was unable to find a solution.

My findings are thus far:

- The "esnecil.ind" that marigold writes in his/her tut is no longer used. Deleting it has no effect.

- The app creates a XXXXXXX._rq files (where XXXXXXXX is varying each time the app is run).

- This file is read by the CrypKey Service (crypserv.exe) and analyzed I guess for valid trial.

- If I stop this service and attempt to run the app, I get exception in ntdll!memmove function (himem area).

I will be grateful for any help.

peterg70: I did try to reverse the SiteKeyGen for CrypKey but alas the program seems to be well written . There are multiple checks for CRC-validity of the site code, validity of the site code itself etc. So, what I did was to brute-force enable the generate button and nop all unnecessary instructions and attempt to generate the license key. But, alas nothing shows up in the "Generate" Edit Box (The Copy button next to it is enabled, though )

Where am I wrong? Pls. advise...

Activating the Generate Button is of no use for the crypkey skw.exe file. (I assume you mean this file)

What you need to do is firstly patch so that the program doesn't tell you that the site code is from another company.

Then you need to add an entry into the license config section.

You will need the following from your target
FILENAME :
USERKEY :
PRODID :
COMPANY NUM :
Enter the above info into the config area.
(company num needs to be put into the skw.ini manually)

If you use thewd ckinfo program (nice util) you will be able to determine most of the required information from the MASTER KEY and the USERKEY in your target.

When you enter the sitecode the skw.exe does the following
1) Checks if the sitecode is valid and is the demo company num (patch this)
2) Checks the filename against whats in the config.
3) IF filename found then checks PRODID
4) IF PRODID is correct Checks Company NUM

When generating an AUTHOCODE you will need the password for the program (From the USERKEY via CKINFO)
Check the level and options you need (trap get_level and get_options calls in cryp95X.dll)
and Generate a working authocode code.

If you need more info than this PM me and I will help out as much as I can

Hi PeterG:

Thanks for your post. It is very informative. I saw this in bits-and-pieces in your earlier posts. Thanks for consolidating everything in this post. I'll surely give this one a try and get back to you, if I need further help.

Thanks,

Hi Guys:

Within 2 mins I find all the necessary inforamation. I just need to patch the invalid Site Code call. And I guess we're done.

Thanks a lot PeterG (couldn't done without you) and Thewd (for the great ckInfo!!!! <--- rocks )

BTW, can you explain in detail how the CrypKey protection works for us guys sakes. Even pointers is sufficient.

May be redundant to explain how current system works if the following news from the crapkey website is something to go by



Can't wait for the link to download it

and then for a program using it

i'm also looking forward to v6, although the protection shouldn't really change much. Appears to support key generation based on the hard disk serial number, and an EasyLicense option (not sure what this does - couldn't get it to work in the beta version)

ckInfo v1.03+ hopefully should already support this version, providing no major changes have been introduced since the beta.

recent versions of the site key generator application appear to contain the code (and gui support) for generating keys for v6, although it doesn't work because the supporting dlls are based on v5
(to enable gui changes (v5.6.133) - change version byte from 0x38 (v5.6) to 0x3C (v6.0) within skw.exe at address 0x41747B)

I had noticed those changes being incorporated into the skw.exe for version 6.0 but my thoughts are that the dll required for authorisation etc will be totally new due to the statement about the patent pending.

I have a feeling that the dll will incorporate new hashing etc but then again they can suprise me and release exactly the same dll.

Please send me unpacker of crypkey and all stuff (Blackos)
and thewd you ckinfo is very interesting you can explain me about this ????


i have unprotect all crypkey software loading as export module in Sice cryp95xx.dll and bpx get_authorization, is easily change jg - jnz, but with new version this routine is packed and only permit patch memory


thanks alll !!!

and please send me all stuff about this !!!

Hi Peterg70:

Thanks a lot for your very informative explanation. Could you send me unpacker of skw.exe.
But what about removing CrypKey protection? Please send me all information and all stuff about this.

Thanks a lot, again.

Firstly

This is not a crack request form. So go and find one if you want answers to the above questions.

Secondly

NO
Work it out for yourself. I never received any file or stuff from anyone. I worked it out myself. Although when I got stuck I asked an intelligent question (NOT give me all info).

Thirdly

I am willing to offer guidance and pointers but I don't do the cracking.
Learn and you shall reap the rewards

Excuse the ramblings
