SSH Tectia

Encryption and Authentication Methods

To increase file transfer speed, the CryptiCore algorithm should be enabled on the server (if available). To allow non-interactive authentication, public keys can be used.

Enabling CryptiCore

The CryptiCore algorithm is supported on x86-based processor architectures with SSH Tectia Server with EFT Expansion Pack and SSH Tectia Server with Tunneling Expansion Pack. It allows increased file transfer speeds for large file transfers.

To use CryptiCore, include the following in the ssh-server-config.xml file:

<connections>
  <connection action="allow" tcp-keepalive="no">
    <rekey seconds="3600" bytes="1000000000" />
    <cipher name="crypticore128@ssh.com" />
    <mac name="crypticore-mac@ssh.com" />
  </connection>
</connections>

Using the SSH Tectia Server Configuration GUI on Windows, this can be set under the Connections and Encryption page, on the Parameters tab. See Parameters.

Enabling Public-Key Authentication

To enable public-key authentication on the server, include the following in the ssh-server-config.xml file:

<authentication-methods login-grace-time="600">
  <banner-message />
  <auth-file-modes strict="yes" mask-bits="022" />
  <authentication>
    <auth-publickey />
  </authentication>
</authentication-methods>

The auth-file-modes element should be set to strict. This specifies that SSH Tectia Server on Unix checks the permissions and ownership of the user's key files used for public-key authentication.

Using the SSH Tectia Server Configuration GUI on Windows, the same settings can be made under the Authentication page, on the Parameters tab. See Parameters (the auth-file-modes option is not available on Windows).
