# in this case we are saving the certificate to the certs folder under /etc/ssl/ which has the following permission 755(drwxr-xr-x) Sudo chown mssql:mssql mssql.pem mssql.key openssl req -x509 -nodes -newkey rsa:2048 -subj '/CN=' -keyout mssql.key -out mssql.pem -days 365 Example, you could create a folder called 'sslcert' under the path '/var/opt/mssql/' and then save the certificate and the private key with permissions on the files set to 600 as show below. You can create folders manually with permission set to 700 (drwx-) and owned by mssql user/group or set the permission to 755(drwxr-xr-x) and owned by other user but still accessible to mssql user group. You should use CA certificates.Д®nsure that the folder/s you save your certs and Private keys are accessible by the mssql user/group and has permission set to 700 (drwx-). Generate certificate (/CN should match your SQL Server host fully qualified domain name)ДЇor this example we use a Self-Signed Certificate, this should not be used for production scenarios.TLS connections can either be client initiated or server initiated. When configured correctly, TLS provides both privacy and data integrity for communications between the client and the server. TLS is used to encrypt connections from a client application to SQL Server. These symbolic links should be named libcrypto.so and libssl.so and placed in the /opt/mssql/lib/ directory. If these symbolic links are not present, SQL Server will load the default configured OpenSSL libraries on the system. This is useful if you want to force SQL Server to use a specific version of OpenSSL other than the default provided by the system.

You can create symbolic links in the /opt/mssql/lib/ directory that reference which libcrypto.so and libssl.so libraries should be used for encryption. Note: Wild Card Certificates are supported.Д¬onfiguring the OpenSSL Libraries for Use (Optional) The Subject property of the certificate must indicate that the common name (CN) is the same as the host name or fully qualified domain name (FQDN) of the server computer.

Usually, the certificate's key usage property (KEY_USAGE) also includes key encipherment (CERT_KEY_ENCIPHERMENT_KEY_USAGE).

The certificate must be created by using the KeySpec option of AT_KEYEXCHANGE.

This requires the Enhanced Key Usage property of the certificate to specify Server Authentication (1.3.6.1.5.5.7.3.1).

The certificate must be meant for server authentication.

The current system time must be after the Valid from property of the certificate and before the Valid to property of the certificate.

Requirements for CertificatesД«efore getting started, you need to make sure your certificates follow these requirements: However, the steps to configure TLS are specific to the operating system on which SQL Server is running.

SQL Server supports the same TLS protocols on both Windows and Linux: TLS 1.2, 1.1, and 1.0. SQL Server on Linux can use Transport Layer Security (TLS) to encrypt data that is transmitted across a network between a client application and an instance of SQL Server.
