Encryption Choices

Use this panel to customize cryptographic algorithms. To provide port security, the TN3270 server uses the encryption services of SSL or TLS to protect data. Your z/OS system SSL/TLS provides a defined set of encryption and data authentication algorithms we refer to as ciphers. The encryption algorithm scrambles the data so that it cannot be interpreted. The data authentication algorithm ensures that the data is delivered completely without alteration.

Before you begin, make some decisions about security.

Steps

  1. Click the button that describes what you want to do (use the defaults, not use ciphers, or select which algorithms).
  2. If you select that you want to specify algorithms, specify if this system is subject to export regulations.
  3. Put a check in the box in front of the ciphers you want to enable. You can select more than one.

You have completed this panel after you have:
