    Hi @Chinni ,

    When enabling channel encryption between the application and SQL Server, users may wonder what encryption algorithm is being used to protect their data. Unfortunately, this isn't an easy question to answer.

    A cipher suite is a set of cryptographic algorithms that specifies the algorithm for key exchange, encryption, and message authentication. What the best cipher suite to use is negotiated by SSL/TLS and depends upon the cipher suites supported by the OS on the client and the server. The client will provide the server with a list of its cipher suites from the negotiated protocol. The server will chose the strongest cipher suite that it is able to support from the client's list.

    Refer to below MS documents, hope these could help you.
