Changing cryptographic settings

Cryptographic keys are used to encrypt passwords and data.

All IBM® Cognos® Analytics server and client components, including Cognos PowerPlay® Client, must use the same cryptographic keys.

During the initial configuration, PowerPlay Client communicates with Content Manager through the gateway to establish trust and obtain cryptographic keys from Content Manager. If the cryptographic keys on the Content Manager computer change, you must update the PowerPlay Client configuration to obtain the new cryptographic keys from Content Manager.

Complete the following steps on each PowerPlay Client computer.

Procedure

  1. Go to the powerplay_client_installation_location\configuration directory.
  2. Delete the cert directory.
  3. Start IBM Cognos Configuration.
  4. In the Explorer window, under Security, click Cryptography.
  5. In the Properties window, update the value of the properties as required to reflect changes in the cryptographic properties on the Content Manager computer.
  6. From the File menu, click Save.

Results

IBM Cognos Configuration creates new cert directory in the configuration directory.
