@@ssl_ciphersuite

The Transact-SQL global variable @@ssl_ciphersuite enables users to see which cipher suite was chosen by the SSL handshake and to verify that an SSL or a non-SSL connection was established.

For example, an isql connection using SSL protocol displays the cipher suite chosen for it.
