I need to transport an index and remount it in a new splunk instance for review. The index has block signing on and Show Source works fine to test integrity on the original splunk instance.
The block signature db is also being transported and included on the new instance exactly as configured on the original. However, the block signature test fails.
All searching activity works perfectly. Only block sign integrity is broken.
Is there a special way I need to work with the block signature db to make this work?
The background here is that a third party needs to review the data and confirm integrity, but can't be given direct access to the original instance. So we have them install Splunk Free and mount up a copy of the index.
I believe that the target system must have at minimum the public key of the signer. I am not sure, but I think that the default key, unless otherwise configured, would be found in $SPLUNK_HOME/etc/auth/audit/public.pem.
