tls1.3 | Pure Python Implementation Of TLS | TLS library

custom-set-variables is a function, not a variable. You need and expression that's a list whose car is custom-set-variables:

Emacs treats “/Users/myusername/.opam/default/bin/coqtop” as a symbol because it's a sequence of ordinary characters. It does not start with an (ASCII) double quote, it starts with the character “ and ends with the character ”. They non-ASCII left and right double quotes. Use the ASCII quote ", which is the string delimiter in Emacs Lisp (and many other programming languages).

The specific wolfSSL option for enabling TLS sessions is HAVE_SESSION_TICKET.

There is not currently an equivalent macro for the ./configure --enable-all option, but you can use the "user_settings" method to get close: https://github.com/wolfSSL/wolfssl/tree/master/examples/configs

Here is an example that configures most of the library options: https://github.com/wolfSSL/wolfssl/blob/master/examples/configs/user_settings_all.h

It's still valid, because:

• a 0-RTT request is more computentionally expensive on both the client as well as the server side than just reusing the connection, since all private key crypto operations and certificate checks still apply
• 0-RTT requests can introduce security issues due to providing a chance for replay attacks (see https://tools.ietf.org/html/draft-ietf-quic-tls-34#section-9.2). Without using the 0-RTT feature a QUIC handshake still requires 1-RTT.

However since QUIC already provides multiplexing multiple requests on a stream the client should not be required to keep a full pool of connections around. A single connection is typically sufficient, as long as the server advertises being able to support a high enough number of streams.

Here is what I used to get it to work. I'm going to leave out the spring security side of it since that is separate from requesting the certificate from the client.

There are so many ways to configure the child pipeline that is used to process the request. Please let me know if there is a more accepted way to configure it.

Configure the HttpServer by adding to the bootstrap pipeline that is applied when a connection is established with the client:

would like to use TLS1.3 in a UWP project

I'm afraid you can't use TLS 1.3 in UWP platform. Derive from official document the max version of supported TLS within UWP platform is 1.2. If you do want this feature please feel free post your requirement with windows feed back hub app, or pay attention to the following UWP SDK update.

At the moment the max version of windows 10 is version 20H2(OS Build 19042.630). The TLS1.3 server works well only when TLS1.3 server is enabled in regedit. But TLS1.3 client does not work even TLS1.3 client is enabled in regedit. At the moment TLS1.3 client only works in Windows 10 Insider Preview Build 20170.

You can set the supported TSL protocols here:

webBuilder.UseKestrel((context, serverOptions) => { serverOptions.AddServerHeader = false;

Yes, but the underlying operating system has to support it.
In your case, you have to enable it in the registry because it's disabled by default.

That depends on the underlying operating system.
.NET uses different implementations based on the OS, e.g. OpenSSL on Linux, Schannel on Windows

TLS 1.3 is supported since .NET Core 3.0, as you can read from the docs.

The statement by the time of .NET Core 3.0 will be modified shortly:

Windows and macOS do not yet support TLS 1.3. .NET Core 3.0 will support TLS 1.3 on these operating systems when support becomes available.

Windows supports TLS 1.3 since version 1903, but it's disabled by default.
There is another question which answers how to enable it on Windows:
how to enable TLS 1.3 in windows 10

TLS 1.3 is enabled by default on Windows 10 Insider Preview builds, starting with Build 20170:
Taking Transport Layer Security (TLS) to the next level with TLS 1.3
According to this article:

TLS 1.3 support will also be added to .NET beginning with version 5.0.

A good summary of the current process is stated by karelz on GitHub (this issue also should track when .NET Framework gets support):
