Attention
SHA256 GIM client certificates
Guardium 12.1 supports both SHA256 and SHA128 GIM certificates. This has the following implications:
- The default certificates could be either SHA256 or SHA128, depending on the GIM server certificate setup. Custom certificates that use SHA256 are more secure and are recommended for GIM connections.
- If your existing GIM clients have the latest GIM bundle installed, you can switch the GIM server certificate between default SHA256 and SHA128 by using the CLI command if needed. GIM connectivity is not interrupted by this switch.
- Guardium 12.1 GIM only verifies bundles signed with SHA256 and requires installation of a transitional GIM bundle to support the GIM client upgrade from the SHA128 signed version to 12.1.
For more information, see Updating Guardium Data Protection GIM clients with SHA256 certificates.
GIM client to connect with default certificates if custom certificates fail
In the event that a connection between GIM and the Guardium server cannot be established by using custom certificates, GIM will use default certificates.
