Hi. I'm here to get you your key back.
I just wrote a utility to extract a key from a key.dat file. This is nowhere near as scandalous as it sounds. It is not possible to rob people of their keys using this utility. Key.dat files are simply your plaintext key encrypted. If you have a key.dat file where you know the key that goes into it, you can actually extract the encryption key from that key.dat. Luckily, this encryption key is unique to your computer and will work on other key.dats in reverse, input the encryption key and out comes the plain text key.
Using the utility I wrote, you must have one key that you actually know and the key.dat file for the key you want to recover. To recover this key, rename the
key.dat file to
keyLost.dat. Then, open Blockland and input the key you know. You can then close Blockland, it has written the
key.dat file. Then, open up Key_Recover.exe (which should be in your Blockland directory) and type in the key you just put in Blockland without any dashes or spaces. It then outputs your recovered key, that easy. The source code for this utility can be found
here, but since I can't post an executable on the forum please PM me for a link to the executable file. I've taken the liberty in already PMing you a link, Kniaz.
