Create a file that contains the password for the crackme2 executable.

• Your file should contain the exact password, no new line, no extra space
• ltrace, ldd, gdb and objdump can help
• You may need to install the openssl library to run the crakme2 program: sudo apt install libssl-dev
• Edit the source list sudo nano /etc/apt/sources.list to add the following line: deb http://security.ubuntu.com/ubuntu xenial-security main Then sudo apt update and sudo apt install libssl1.0.0
