As for the AES key, I am hashing the company GUID the database record belongs to using SHA256 (resulting in the same key on each server that is trying to decrypt the record from the DB) I am unable to use SQL encryption for various reasons and must use code for encryption/decryption. Delete existing encryption keys and unusable encrypted content when you cannot restore the symmetric key. Recreating Encryption Keys. If you have evidence that the symmetric key is known to unauthorized users, or if your report server has been under attack and you want to reset the symmetric key as a precaution, you can recreate the symmetric key.

Purpose

The purpose of this guide is to describe what Secure Store in File System is, to provide guidance on how to check for SSFS consistency and to list all related documentation that is currently available to assist with any troubleshooting issues.

Description

Server side Encryption Keys are available within SAP HANA designed to protect your data from unauthorized access. By default, these are generated during installation, or on delivery of your appliance. It is recommended that these keys are changed immediately for security reasons.

The following keys can be changed:

Master key of the Instance SSFS
Instance SSFS protects root encryption keys. Root keys protect all encryption keys used in the HANA Database from unauthorized access

Malwarebytes 3.0 premium key generator. 2. Master key of the system public key infrastructure (PKI) SSFS

PKI SSFS protects the X.509 certificate infrastructure used to secure SSL/TLS communication between hosts or between multi-tenants databases.

3. Root key of the internal data encryption service.

This key is used to encrypt SAP HANA XS-based application encryption keys. e.g. logon of XS applications to remote connections.

How to Change the SSFS Master Keys

Please follow the procedure described in SAP HANA Administration Guide chapterChange the SSFS Master Keys.

SSFS and System Replication

In system replication scenarios, the location of the SSFS master key needs only to be configured. The file will be copied automatically. See SAP Notes 2193235 , 2202010 and 2194396 regarding troubleshooting SSFS with system replication sites.

SSFS and Multitenant Systems

In a multitenant environment, the system database and all tenant databases have their own encryption keys for both data encryption service and data volume encryption.

SSFS and Homogenous System Copies

For system-based copies, the instance SSFS master key file must be manually saved and restored in order to prevent data loss. See SAP Note 2097613 and 2134846 regarding troubleshooting SSFS with system copies.
