To obtain a SQL Server certificate from Microsoft, you need to follow these steps:
- Choose the Type of Certificate: Determine whether you need a self-signed certificate or one issued by a Certificate Authority (CA). For production environments, it's recommended to use a certificate from a trusted CA.
- Create a Certificate: If you decide to use a self-signed certificate, you can generate one using SQL Server Management Studio or PowerShell. For a CA-signed certificate, you will need to generate a Certificate Signing Request (CSR) and submit it to the CA.
- Install the Certificate: Once you have the certificate, install it in the appropriate certificate store on your SQL Server machine. You can use the Certificates snap-in in MMC (Microsoft Management Console) to manage certificates.
- Configure SQL Server to Use the Certificate: Use SQL Server Configuration Manager to specify the certificate for encryption. Ensure that the SQL Server service account has permission to access the certificate.
- Verify the Certificate: Check that the certificate meets the requirements for SQL Server encryption, including being valid for server authentication and having the correct Subject Alternative Name (SAN) entries.
- Test the Configuration: After configuration, test the SQL Server instance to ensure that it can successfully use the certificate for encrypted connections.
For detailed requirements regarding certificates for SQL Server encryption, you can refer to the following:
- The certificate must be in the local computer certificate store or the SQL Server service account certificate store.
- The SQL Server service account must have the necessary permissions to access the TLS certificate.
- Ensure the certificate is valid and not expired.
By following these steps, you can successfully obtain and configure a SQL Server certificate.
