            Disable TLS 1.3 in Twisted Python
            Asked 2021-Jul-12 at 10:38

            How do I disable TLS 1.3 in a Twisted server? Here's my code that should disable TLS 1.3, but doesn't:



            Answered 2021-Jul-12 at 10:38

            This was caused by mixing an old Python OpenSSL package with a modern OpenSSL native library. Both provided by Ubuntu 18.04. The fix was to update the Python OpenSSL package, using PIP instead of a system package.

            Why this fails:

            • The OpenSSL native library enables TLS 1.3 by default.
            • The old Python OpenSSL package does not expose the constants needed to turn TLS 1.3 off.
            • The modern Twisted checks the OpenSSL Python package, sees that it does not expose the constants needed to turn TLS 1.3 off, and wrongly assumes that the OpenSSL native library does not support TLS 1.3. It doesn't provide any warnings about this.

            "nghttp2::asio_http2::client" with TLS 1.3 - SSL_CTX_set_cipher_list doesnt add cipher suite in cipher suites
            Asked 2021-Apr-11 at 18:30

            I use nghttp2 asio_http2_client with TLS 1.3 protocol, but when i try to add additional suites in cipher suites list via SSL_CTX_get_ciphers function, i don't see anything changes in my Client hello message. I.e. cipher suites list stay without changes.

            My code example:



            Answered 2021-Apr-11 at 18:30

            If you go to the documentation for SSL_CTX_get_ciphers it states:

            SSL_CTX_set_cipher_list() sets the list of available ciphers (TLSv1.2 and below)


            This function does not impact TLSv1.3 ciphersuites. Use SSL_CTX_set_ciphersuites() to configure those.

            So you need to go read the SSL_CTX_set_cipher_list API as the v1.3 cipher list is a lot different and much smaller than up to v1.2 cipher list.

            HTTPS GRPC connections from C core clients to .NET core server: TLS handshake failure
            Asked 2021-Mar-12 at 00:21

            This question is closely related to one I asked yesterday, but my diagnostic information is different enough that I thought I'd update and resubmit: let me know if I should delete one of these.

            I have a toy GRPC server written in .NET core that I need to connect to using a client using the grpc C core.

            You can find the Startup.cs and Program.cs for the .net core server here. Nothing too interesting, except a call to UseHttps. I've verified the server works by connecting to it (over https) from a .net core client.

            However I've tried to connect to this server from clients written in both C++ and python now, and the result is a GRPC error 14 and the following message on the client side



            Answered 2021-Mar-12 at 00:21

            My connection troubles seem to have been caused by some misconfiguration on my machine, as I was unable to reproduce the errors on other setups. So that settles the "how do I get this to work?"

            In response to those three specific questions I answered.

            1. The helpful folks on my grpc issue came to the conclusion that no, the mixing of TLS versions I mentioned is not a problem

            2. I'm still not sure what is causing one client hello packet to be rejected and the other accepted, but again it seems to be something specific to my machine which is not a problem on fresh Windows server 2019 or windows 10 VMs I've created

            3. Not sure about this one: I'm pretty sure that I'm setting that environment variable correctly but I'm not sure why openssl doesn't recognize that value. Also, I don't think GRPC_SSL_CIPHER_SUITES has any effect on windows

            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.

            OpenSSL 1.1 get a cipher suite by the IANA ID
            Asked 2020-Aug-20 at 08:09

            In OpenSSL 1.0.2 we have used the ssl3_get_cipher_by_id() function found in s3_lib.c to obtain a cipher suite (SSL_CIPHER*) using the IANA ID.

            For example, the ID 0x00,0x2F would give us the TLS_RSA_WITH_AES_128_CBC_SHA cipher suite as an SSL_CIPHER struct.

            However, this function is not listed in the OpenSSL documentation from 1.0.2 and above, and while the function is still available in 1.1.1 it does not seem to work for newer cipher suites, e.g. returning NULL for both of these:



            Answered 2020-Aug-19 at 21:41

            You could use SSL_CIPHER_find(), which

            ... returns a SSL_CIPHER structure which has the cipher ID stored in ptr. The ptr parameter is a two element array of char, which stores the two-byte TLS cipher ID (as allocated by IANA) in network byte order.

            Install testssl

            create a server cert and key the common name is 'localhost', but can be anything usually the host name. create a client cert and key with the same common name. move server.key and server.crt into the postgresql data directory. copy server.crt to server_ca.crt, this will be used by the client to verify the server certs. copy client.crt to client_ca.crt and move to the postgresql data directory. create a database called testssl and a user named test. confirm that you can connect with psql and get an ssl connection. psql uses the following environment variables. you may have to make pg_hba.conf more restrictive to ensure that only an ssl connection is possible to that database/user/host combination. first we have to change the client key into a format java understands. This will ask for an encryption password. For this example there will be no password, however it is important that you provide the same password in the java code SSL_PASSWORD.
