Added Password encryption

Added Password encryption to generate encrypted password for automated joining with readfile
encryption will genetate encrypted.dat > (your password encrypted)  and private_key.pem  public_key.pem
all tree files are needed to decrypt the password. Find a way to get private_key.pem from outside source.
Please do NOT store your private_key.pem with the other files untill the joining process. encrypt a  password with sudo sh ADconnection.sh -p
