To encrypt your passwords, use the global configuration command
service password-encryption
Line passwords are encrypted with type 7 encryption.
The service password-encryption global configuration command will encrypt all non-encrypted passwords (enable password, line console, line vty, ect) with a basic encryption algorithm.
All services must provide an encrypted password to function.
