Contribution for /etc/passwd and /etc/shadow

[Ali Koca]

We must develop absolutely secure hash algorithm system like using secure hash algorithm SHA-1 for security of Aero, it will also use shifting which is another secure algorithm for keeping passwords safe. And add a guide of password manager for Aero that does describe how this works and improve new hashing techniques similar to ROT13. Also new future changes will make development of "I'm a teapot" HTTP code status algorithm easier to understand if this server is a teapot, we prefer coffee instead of tea.
