title: How to use encrypted and decrypted passwords in shell script
body: <p>I am writing a shell script which executes a command which requires a password. I cannot put password in plain text in the script. I read about openssl encrypt decrypt mechanism but for encrypting a file again I need a password which again I cannot put in the script. I am clueless what is the best way to have a script execute a command using a secure password.</p>
