targetted application: Digital Signer (Softpedia.com)
app by me

Files (3):

Code:

# Files present in "[Digital Signer Key Manager] - Full Application.zip" (34kb) # - Digital Signer Key Manager.exe | 49kb - GetMachineID.exe | 14kb - Interop.Scripting.dll | 23kb

You cannot share keys to other people since a hardware ID needs to be created

Notes:
- The theorized version only skips one of the first step to validate keys, which is the encryption & decryption, this version of the application has everything fully working. (the application author added buttons to enter our own license key in 10.3.0)
- There is a 2nd executable given which generate the Machine ID, this is required to create a valid license key for your computer only, you cannot share keys with other
- 49kb | GUI
- not obfuscated, feel free to edit it

Workings of key validation:

Spoiler:

the key is first decrypted into a string with this patern:

Code:

MACHINEID_LICENSETYPE_STARTDATE_ENDDATE_DigitalSigner

verifies via a BinarySearch is the string contains "PROFESSIONAL" or "TRIAL"
the string is then split at every underscore:

Code:

MACHINEID LICENSETYPE STARTDATE ENDDATE DigitalSigner

It then check if the machine id is the same as the machine the application is currently running on
then checks the license type, if the dates are valid & if the string contains "DigitalSigner"

thats it

Virustotal Scan [4/66] (Digital Signer Key Manager.exe)
Virustotal Scan [3/66] (GetMachineID.exe)

This Is not really a cracking tool, so I've moved It from that forum to Software & Programs.

This tool still works with Digital Signer 10.4 & Digital Signer 10.5!
