Specifying SFTP Algorithms

Certain cipher algorithms allow for variable sized keys, while others only allow a specific key size. The length of the key correlates with the strength of that algorithm; larger keys are harder to break than shorter keys. EFT Server supports the ciphers shown in the SFTP Settings dialog box below.

To specify encryption algorithms (ciphers)

1. In the administration interface, connect to EFT Server and click the Server tab. (SFTP should be enabled.)

2. In the left pane, click the Site you want to configure.

3. In the right pane, select the Connections tab.

4. Select the SFTP (SSH2) check box, then specify the port, if different from the default shown.

5. Click SFTP Config. The SFTP Settings dialog box appears.

   

6. In the Allowed ciphers list, clear or select the check boxes to specify which ciphers you want to allow for encrypting SFTP sessions.

7. Click OK to close the dialog box.

8. Click Apply to save the changes on EFT Server. EFT Server tries each selected algorithm with the client until one is agreed upon.

Refer to Creating an SSH Key Pair for instructions for creating key pairs, if necessary.
