Encryption Algorithms
Overview
In SFTP Gateway version 3.5.0, we added a section under the Settings page for configuring SFTP encryption algorithms.
Under the Encryption Algorithms section, you can specify exactly which HMACs, Public Keys, SSH2 Ciphers and Key Exchange algorithms that the server supports.
By default, only the PARANOID and STRONG algorithms will be allowed. Clicking Reset to Default will reset to the default configuration as seen in the image above.
In order to make edits, change the mode from Viewing to Editing. Any changes made are saved automatically.
