Port 80 is typically used for unencrypted HTTP traffic while port 443 is the common port used for encrypted HTTPS traffic. One of the main ways of achieving this is to use a different port number for TLS connections.
Since applications can communicate either with or without TLS (or SSL), it is necessary for the client to request that the server set up a TLS connection. TLS builds on the now-deprecated SSL ( Secure Sockets Layer) specifications (1994, 1995, 1996) developed by Netscape Communications for adding the HTTPS protocol to their Navigator web browser.Ĭlient-server applications use the TLS protocol to communicate across a network in a way designed to prevent eavesdropping and tampering. TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999, and the current version is TLS 1.3, defined in August 2018. In technical writing, references to "( D) TLS" are often seen when it applies to both versions. The closely related Datagram Transport Layer Security ( DTLS) is a communications protocol that provides security to datagram-based applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols. The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. This will help us and others in the community as well.Transport Layer Security ( TLS) is a cryptographic protocol designed to provide communications security over a computer network. Please "Accept the answer" if the information helped you. The following example shows TLS 2.0 client set to the disabled state:Īlso you can try this tool to verify the version. The following example shows TLS 1.0 client set to the Enabled state: In order to override a system default and set a supported (D)TLS or SSL protocol version to the Enabled state, create a DWORD registry value named "Enabled" with a non-zero value, and a DWORD registry value named "DisabledByDefault" with a value of zero, under the corresponding version-specific subkey.

Schannel SSP implements versions of the TLS, DTLS, and SSL protocols. If the reply is helpful, please Upvote and Accept it as an answer.
