SSH Host Keys

This sub-section allows you to create and import/export your SSH2 (SFTP/SCP) protocol handler's host keys.

SSH host keys are cryptographic keys used by the server to identify itself to clients during the initial handshake of an SSH, SFTP, or SCP connection. When a client connects, it verifies the server's host key to ensure it is communicating with the correct server and to prevent man-in-the-middle attacks.

Syncplify Server! supports the following types of SSH host keys:

• RSA
• ECDSA
• Ed25519

You can generate new host keys, import existing ones, or export their public part to be given to clients.

NOTE

While RSA keys are still supported for compatibility, they are now considered insecure and should not be used in production environments where security is a priority. For best security, use ECDSA or - even better - Ed25519 host keys.
