So lets say I have a .sh script and I have to input a password in it , will there be some kind of cache where the bash inputs are stored ? And if yes please tell me whre so I can ersase it . Would the attacker be able to decrypt something which was encrypted with a shell / bash script passed through another program , if he had physical access to the machine ? If yes , how can I prevent that ?
I didnt find anything on the topic .
Thank you !
part of the script as example :
echo "please input your password to be hashed " echo "" stty -echo read -p "Password :" x; echo stty echo echo "" echo "please repeat the password " echo "" stty -echo read -p "Password :" x2; echo stty echo if [[ $x == $x2 ]] ;then echo "" echo "Passwords match !" echo "" sleep 2 else echo "" echo "passwords dont match :( " echo "" sleep 2 echo "exiting" echo "" sleep 1 exit 1 fi
