We can use the following registry keys and their values to enable RC4. This cipher suite's registry keys are located here:Enable RC4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 128/128] "Enabled"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControl...
Step 2: Verify the cipher suite configurationIf you have specific cipher suites configured in the Windows registry key HKLM\SOFTWARE\Policies\Microsoft\Cryptography\Configuration\SSL\00010002, these settings might be preventing the Windows Update clie...
Claes, I suppose you could delete from the registry the ones you didn't want your browser to use. We haven't tested this, so I can't predict how it would behave. And I don't know of any websites that would return details on which suite was chosen. If anyone el...
2. Add the following ciphers to the end of the existing cipherSuite: ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA: ECDHE-RSA-AES128-SHA To enable TLS 1.2 support on Windows Server 2008 R2: 1. Add key to the registry: HKEY...
There does not seem to be any mechanism for .NET Core on Linux to adjust the cipher suite offered when using HttpClient and friends, and therefore .NET Core cannot currently be used in most government installations. This is a key blocker to adoption for us. [EDIT] Add dependency on ...
If A mark in SSL labs is critical for you, you should consider excluding the first cipher suite (TLS_DHE_RSA_WITH_AES_128_GCM_SHA256) that imply DHE key exchange leaving cipher suites with ECDHE key exchange only: TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P256...
The default ordering in Windows Server 2016 is compatible with HTTP/2 cipher suite preference. Additionally, this ordering is good beyond HTTP/2, as it favors cipher suites that have the strongest security characteristics. Therefore, the default ordering makes sure that HTTP/2 on Windows...
Update any servers that rely on RC4 ciphers to a more secure cipher suite, which you can find in the most recent priority list of ciphers. If you have the need to do so, you can turn on RC4 support by enabling SSL3. To have us do this fo...
https://support.microsoft.com/en-us/help/4032720/how-to-deploy-custom-cipher-suite-ordering-in-windows-server-2016 Keep in mind that some cipher suites are not available on older Windows Servers, so even if they are enabled in the registry, they will not be offered to the server in the...
