Dinkey dump and emulation (and training)
Hello everyone!
I received a software protected with a Dinkey (presumably 1S) and, although it works flawlessly, I would like to delve a bit deeper in dongle protection - moreover I am designing a security system myself, so it turns out useful.
I have used the nodongle script to dump its internal memory, obtaining the serial, key value and memory content, gotten Multikey with its license and I have two (and half) questions:
1) is there a copy of Dink2Mk still up and available to us mere mortals?
2) is it enough to have the system up and running and available for testing?
half) are there docs out there outlining the dongle's inner workings, implementation and anti-debugging techniques?
Thanks!

Re: Dinkey dump and emulation (and training)
The software is nevrokard.
I converted the dump, plugged it into the emulator and it runs as expected in isolation mode.
I noticed the dump data, when converted into the reg file, is byteswapped, is that an added security layer or just the dumper tool?
Also, are there any public docs on dongle encryption, if any? I am curious to run a relative search for the license data, which seems to be in a separate data chunk after a series of 5a4d's (assuming the first chunk stands for the key, however any change breaks the licensing. Does dinkey also store a checksum of its content?

Re: Dinkey dump and emulation (and training)
dinkey have many tricks like check sum, seh, etc.
the dongle memory context also include version number, time of expirity, number of run. all ciphered.
show the dongle dump here or pm

Re: Dinkey dump and emulation (and training)
Thanks for the info, Bfox. I will contact you in pm for more info.
I am sure the data is somehow checked against a checksum as the first data chunk contains two series of bytes that differ for a single byte.
Are there any signature packs around for disassembling a dinkey protected sw?

Re: Dinkey dump and emulation (and training)
I changed the date in the dongle.
ddlook.exe tells me "no limit"
but the software always gives me the same date "Expires: 08/01/2015" why?
I read in the sdk but I did not find what to change
Who can help me

ddlook.exe tells you "no limit" only for run the software with dongle shell

DINKVALUE =4abf93ba
EFD033C7C20CAF98A8186B41FEC47763 = NO LIMIT
EFD437CBCE00AB94A898EBC17E4477E3 = Expires: 2015-08-01
execs 2 word No. of executions left
exp_day 1 byte expiry day
exp_month 1 byte expiry month
exp_year 2 word expiry year
feature 4 int feature
AND CORRECT?
OR MISSING SOME TYPE

Ho anche ansioso di
Spero di trovare la medicina
o si aspettano calo dei prezzi
crittografia che utilizza il controllo di copia
