# Transfer Family Host Key

Transfer Family Host Key in AWS is a resource used to manage SSH host keys for AWS Transfer Family servers. It allows secure identification of the server to clients during SFTP, FTPS, or FTP connections. By using host keys, clients can verify they are connecting to the correct server, ensuring trust and preventing man-in-the-middle attacks.
