SSL certificate and key management



Search Tips   |   Advanced Search



SSL security can be used for establishing communications inbound to and outbound from an endpoint. A certificate and an SSL configuration must be specified for the endpoint.

To configure security for SSL and key management, certificates, and notifications, go to...

Configuration settings

Use FIPS (FIPS) algorithms

Set FIPS-compliant Java cryptography engine enabled.

  • Does not affect the SSL cryptography that is performed by the application server for z/OS System SSL (SSSL).

  • Does not change the JSSE provider if this cell includes any Application Server versions before the appserver for z/OS V6.0.x.

When you select...

    Use the FIPS (FIPS)

...the LTPA implementation uses IBMJCEFIPS, which supports the FIPS-approved cryptographic algorithms for...

  • Data Encryption Standard (DES)
  • Triple DES
  • Advanced Encryption Standard (AES)

Although the LTPA keys are backwards compatible with prior releases of the appserver, the LTPA token is not compatible with prior releases. In prior releases, the application server did not generate the LTPA token using a FIPS-approved algorithm.

The IBMJSSE2 JSSE provider does not perform cryptographic functions directly, and therefore does not need to be FIPS-approved. Instead, the IBMJSSE2 JSSE provider uses the JCE framework for cryptographic functions and uses IBMJCEFIPS when FIPS mode is enabled.

The IBMJSSEFIPS provider is not supported on the HP-UX platform. However, the IBMJSSE2 provider, which uses IBMJCEFIPS, is supported on the HP-UX platform.

Default: Disabled

Dynamically update the runtime when SSL configuration changes occur

All of the SSL-related attributes that change must be read from the configuration dynamically after they have been saved, then reused for new connections. To avoid customer impact, it is recommended that changes to production servers be made during off-peak periods.

Default: Disabled

When this option is selected, the configuration is updated each time you configure an SSL communication.
