Amazon Transfer Family now supports up to ten host keys per SFTP server. In addition, ED25519 and ECDSA key types are now supported for server host keys. Previously, Amazon Transfer Family only supported one host key per server, and only the RSA key type.
These enhancements allow you to move your existing SFTP servers with multiple host keys and host key types to Amazon Transfer Family. You will also be able to add and tag host keys before rotating them, giving you more control over your managed file transfer environments.
Multiple host keys and host key types are supported in all Regions where Amazon Transfer Family is available, including the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD. You can configure server host keys using the Amazon Web Services Management Console, Amazon Transfer Family API, or Amazon Command Line Interface (CLI).
