I released version 1.1; will print keys found to "KeysFound.txt" if user forgets to add -o option or pause at end of batch file. Try with no -o
https://github.com/WanderingPhilosopher/VanBitCrakcenS/releases/tag/1.1
Actually it will print KeysFound.txt whether -o was used or not, but a fail safe for now.
Now I roll back to using version 1.0
I use -o output for save result that save difference key
version 1.1 not save from command -o output
but every thing move to save on KeysFound.txt
