vault-door-1

Challenge

This vault uses some complicated arrays! I hope you can make sense of it, special agent. The source code for this vault is here: VaultDoor1.java

Solution

In the file each character is by a number so the password can be put back into order. I just went through a bash one liner to get the correct output.

grep password VaultDoor1.java | awk '{print $1 $3}' | grep charAt| cut -d '(' -f2 | sed 's/)/ /g' | sort -n | cut -d' ' -f2 | sed 's/;//g' | sed "s/'//g" | tr -d '\n'
