    In the guide below it's recommended minimum TLS 1.2:

    Does anyone help me to find the hexadecimal values for the two voices in the image?

    For the other 3 Cipher Suites to be removed,enter:

    --cipher-suite-blacklist=0x002F,0x0035,0x000A

    The website below is not available if you delete the insecure cipher suites:

    Incorrect, that website supports TLS 1.2 as you can see here: https://www.ssllabs.com/ssltest/analyze.html?d=www.linear.it

    If you cannot access it, there's something wrong on your end.

    No offense but this entire topic is about TLS 1.2 and was never about specific ciphers.
    If you look at the results for that website, it only supports weak ciphers for ALL TLS versions.
    Coming to this thread and saying "I disabled 5 ciphers and now I can't access this website on ANY version of TLS is off topic and entirely his own fault.
    This thread isn't for reporting bad websites...

    No offense taken. The topic is indeed about TLS and not about specific ciphersuites, but Sampei's post was about ciphersuites and did not mention the TLS version, so his post was not incorrect.
    True, I phrased it that way because secure AEAD ciphersuites were introduced with TLS 1.2, so it isn't possible to do secure ciphers with TLS 1.1 and earlier.(Though I just saw that SSL Labs only classifies AES-CBC and CAMELLIA-CBC as "weak" when they aren't combined with Forward Secrecy, though they aren't highlighted in green either.)

    Hi.
    Has anyone enabled TLS 1.3 Draft28 in chrome?

    https://datatracker.ietf.org/doc/rfc8446/

    chrome://flags

    TLS 1.3

    Enabled-Draft28

    It seems that the default is Draft 23.

    Yes.
    TLS 1.3 Draft 28 is the final version.

    Even if the test below has many obscure points, it is possible to see before and after:

    Does any user know a better test?

    New test:

    https://tls13.1d.pw/

    In Windows XP only by installing 360 Extreme Browser it is possible to pass the above test.
    Probably even Maxthon can pass the test.
