Open that file in a text editor and you would possibly see mtp written there. Repace ~/ with home directory of your OS. Open a shell on PC and type: adb pull /data/property/ ~/

Since I would never try step 1., I would do the following: For Jellybean 4.2.1: You should try your pattern-cracking software (or whatsoever the genre it has) from inside the Stock Recovery to see whether it works with the former's environment (ADB shell available there or not).If your Stock Recovery allows ADB shell access then you may also consider this solution. Note that this method is tested on Stock Android 4.2.1 and Stock CM 12.0 (Android 5.0), both devices having custom Recovery (ADB always enabled as default). Based on OP's clarification done in the comments below Izzy's answer, I propose the following solution if one's device is locked out and ADB is not enabled under Settings.
