Installing Service Pack 4

If you are using VisiBroker 8.5 Service Pack 4, you must:

1	Install VisiBroker 8.5, as described in this Installation Guide.

2	Install Service Pack 4 by downloading the Service Pack release archive to your <VBROKERDIR> folder and unpacking it in the same folder.

3	At VisiBroker 8.5 SP4, the only security provider supported by default is OpenSSL. If you use OpenSSL, you should update to the latest version as described in the Security Provider section.

However if you are upgrading an existing VisiBroker installation that uses the Certicom Security Provider supported in previous releases, and you wish to continue to use Certicom, see the instructions in the Security Provider section.

Security Provider

Prior to version 8.5 SP2, VisiSecure supported the Certicom security provider. At version 8.5 SP2, VisiSecure for C++ supported a choice of security providers, Certicom or OpenSSL.

From 8.5 SP4, the Certicom security provider is deprecated. It is currently supported only for backwards compatibility, and Micro Focus recommends that Certicom users switch to using OpenSSL.

The VisiBroker 8.5 SP4 main release does not include an update to the security providers. If you use OpenSSL, upgrade to the latest OpenSSL release (1.0.2j) by downloading and installing the separate VisiBroker 8.5 SP4 OpenSSL Security patch.

Existing VisiBroker users upgrading from previous versions can switch between security providers by using the SelectSecurityProvider utility which was delivered as part of SP2. For details of how to do this, see the section Specifying the Security Provider in the VisiBroker Security Guide.
