The aes sub-system allows you to manage AES256 keyfiles and perform encryption and decryption.
The aes commands provide tools to manage Geneos AES256 key files as documented in the Secure Passwords section of the manuals.
In addition to the functionality built-in to Geneos as described in the Gateway documentation these encoded password can also be included in configuration files so that plain text passwords and other credentials are not visible to users.
