Restore SSRS Encryption Key using Deployment Script: A Step-by-Step Guide
SQL Server Reporting Services (SSRS) uses encryption keys to secure data and configurations. Losing this encryption key can result in issues with report processing, subscriptions, and data sources. This guide provides a step-by-step process to restore the SSRS encryption key using a deployment script, specifically for scenarios where the encryption key is lost during a sysprep image creation process. By following this guide, you will be able to restore the SSRS encryption key, ensuring the smooth operation of your reporting services.

1. Preparing the Environment
Before you start the restoration process, prepare the environment by ensuring you have the following:
- Access to the server where SSRS is installed
- The SSRS report server database backup file
- A valid encryption key backup file
Restoring the encryption key from a backup requires the backup file and access to the original report server database.
2. Creating the Deployment Script
Create a new PowerShell script or modify an existing deployment script to included the necessary commands for restoring the SSRS encryption key:
# Set path to SSRS configuration file
$configFile = "C:\Program Files\Microsoft SQL Server Reporting Services\ReportServer\RSReportServer.config"
# Load the SSRS configuration
$ssrsConfig = New-Object Microsoft.SqlServer.ReportingServices.RsConfigTool
$ssrsConfig.Load($configFile, $true)
# Path to the encryption key backup file
$keyBackupFile = "C:\path\to\encryption-key-backup-file.snk"
# Restore the encryption key
$ssrsConfig.EncryptionConfig.DoSimpleKeyRestore(
$keyBackupFile,
[Microsoft.SqlServer.Management.SecureStorage.SecureStorageProviderType]::WindowsDataProtection
)
# Save the modified SSRS configuration
$ssrsConfig.Save($configFile)
Save this script as "Restore_SSRS_Encryption_Key.ps1" and ensure that you save it in a convenient location.
3. Restoring the SSRS Encryption Key
In order to restore the SSRS Encryption Key, follow these steps:
- Open PowerShell as an administrator
- Run the previously prepared script using the following command:
./Restore_SSRS_Encryption_Key.ps1
This command will restore the SSRS encryption key using the backup file provided in the script.
4. Testing the restored Encryption Key
Test the encryption key to ensure that it is restored correctly:
- Open the SQL Server Management Studio (SSMS) and connect to the report server database
- Execute the following T-SQL query
USE ReportServer
GO
SELECT EncryptedValue
FROM Keys
The returned values should match the expected encrypted values. A successful test confirms that the encryption key has been restored properly.
5. Summary and References
This article has provided a step-by-step guide on restoring an SSRS encryption key using a deployment script. The guide covered the following main steps:
- Preparing the environment
- Creating the deployment script for restoring the SSRS encryption key
- Restoring the SSRS encryption key using the deployment script
- Testing the restored encryption key in SSRS
By following these steps, you will be able to restore the SSRS encryption key successfully, resolving any issues derived from losing the encryption key during sysprep image creation.
