SSL connectivity in Azure Database for MySQL
Azure Database for MySQL supports connecting your database server to client applications using Secure Sockets Layer (SSL). Enforcing SSL connections between your database server and your client applications helps protect against "man in the middle" attacks by encrypting the data stream between the server and your application.
By default, the database service should be configured to require SSL connections when connecting to MySQL. We recommend to avoid disabling the SSL option whenever possible.
When provisioning a new Azure Database for MySQL server through the Azure portal and CLI, enforcement of SSL connections is enabled by default.
Connection strings for various programming languages are shown in the Azure portal. Those connection strings include the required SSL parameters to connect to your database. In the Azure portal, select your server. Under the Settings heading, select the Connection strings. The SSL parameter varies based on the connector, for example "ssl=true" or "sslmode=require" or "sslmode=required" and other variations.
Currently the TLS version supported for Azure Database for MySQL are TLS 1.0, TLS 1.1, TLS 1.2.
