Open95Keygen is a portable open source program that generates random valid Product Keys (both OEM and Retail types) for Microsoft's Windows 95 and Windows NT 4.0 operating systems.
The Windows 95/NT 4.0 OEM/Retail Product Key algorithms have been reverse engineered by many people. Open95Keygen is a clean room design implementation not based on any existing software, it is written based on the specifications of the algorithm which is inherently not copyright infringement. I was inspired to write Open95Keygen after watching the YouTuber stack smashing's video Why 111-1111111 is a valid Windows 95 key.
Changes:
-
Implemented my ezre build system.
-
Bug fix for issue #2. The last digit of the 'divisible by 7 with no remainder' portion of OEM keys is now checked to ensure it is not 0, 8, or 9. No more invalid keys.
-
Cleaned up code and documentation.
-

This is a command line program, so on Windows you first must open the command.com or cmd.exe program. Then just drag o95kg.exe into the command.com or cmd.exe window and press the enter or return key.
On Linux, you may be able to just double click the o95kg file to start Open95Keygen. If this does not work, start your terminal program and execute ./o95kg from inside the release directory.
On Windows 95/NT 4.0, if you see the word OEM in between where you enter the Product Key, use the generated OEM Product Key. If you do not see the word OEM when asked to enter a Product Key, use the generated Retail Product Key:
