Crack encrypted master Key (AES 256 CBC with Padding)
Well this is almost infeasible but Murphy's law say that:
Anything that can possibly go wrong, does
in other words
if something can happen, it will be happen
An AES key is an array of 32 bytes length this a chance of 1 of 2^256 This number have 78 decimal digits

When the correct key is found the code works proof of concept
Today I can test around 100 Millions AES keys per second with Intel AESni instrucction with 3 threads on an Intel Xeon CPU E3-1271 v3 @ 3.60GHz
first compile, to do it you need yasm.
sudo apt install yasm
after that only use make
make
execute
./crackbtcshell
now one wild shell appears

Now you can load a ckey, set the number of threads, quiet the output and some others configs
crackBTC > set quiet 1
crackBTC > set threads 2
crackBTC > load ckey 527ff070371320bb53f57b2d470bd897c7a09ae4b77f1f463d9fc1d5ce9a01d46a6d08dee559a9bbbc9d993bc4c287c4
