Enable TLS 1.2 on windows server 2008 R2 - iis

I am trying to enable TLS 1.2 on windows server 2008 R2. I have made registry entries to enable TLS 1.2 as mentioned in below link : http://forums.iis.net/t/1201043.aspx.
I have also tried powershell script in link : http://www.hass.de/content/setup-your-iis-ssl-perfect-forward-secrecy-and-tls-12
While monitoring through wireshark i found that Client hello message is sending version TLS 1.2 and protocol is showing TLSv1.
Server hello message is showing tlsv1 in protocol field and version TLS 1.0 .
I don't know if i am missing anything to enable TLS 1.2. I think i have made all the registry entries.
Any help will be appreciated.
Above mentioned services are runnig in HASP server and running on 443 port.
Another strange thing is i am using IIS 7.5 server When i deploy another srvice on 8443 port. it is running on TLS 1.2 only from ie 9. Both IIS 7.5 service and Hasp server service are running in same machine. But throgh wireshark it is showing TCP protocol only. NO SSL protocl is used here https communication. How is it possible?
Also last point even if i disable SSLv3 from server registry or remove all entries. url still works on sslv3.
Is it possible that we need to update some other files on windows server.?

Same issue - did all steps mentioned in documentation but no luck enabling TLS 1.2 on the Win 2008 or Win 2012 :/.
Some info from logs:
Enabled SecurityProtocol`s: SystemDefault
.NET Runtime: 4.8.4069.0
Modified registries by disabling all others and enabling only TLS 1.2
required updates (kb3140245)
also tried to install "MicrosoftEasyFix51044"
Using "WebRequest.CreateHttp(url)" - still fails with error
ERROR - The request was aborted: Could not create SSL/TLS secure channel.
Updated answer:
At least for us answer was that Win 2008/2012 and API/service which with we was trying to communicate using TLS 1.2 - do not have same cypher suite - so is not able to communicate. From links information looks like there is only one way to upgrade windows to 2016+.
Adding Cipher suite to TLS1.2 of HttpClient of dotnetcore 3.1
https://learn.microsoft.com/en-us/answers/questions/227738/windows-server-2012-r2-tls-12-cipher-suites.html
In our case service was using/supporting (and windows not):
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (ecdh_x25519) - A
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (ecdh_x25519) - A
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 (ecdh_x25519) - A

How to disable TLS 1.0 and 1.1 serverside support for my app (hosted on AWS)

I need to work on a nodejs application. The code is using http.createServer() method to create a server. The ssl configurations are taken care at a higher layer than the application code, that's why the code does not use https object with certificate options. I need to disable the support for TLS 1.0 and TLS 1.1 from this application.
How can I do this?
Thank you.
I figured it out. Marc was right to say that it should be done where the SSL configuration is done.
Basically, the ssl configuration was done manually from the AWS console (In the load balancers, there is an option to add TLS listeners). I just changed the Security Policy for the HTTPS listener and used the recommended latest one and it worked.

How to enable TLS instead of SSLv3 between Web Server and App Server (WebSphere 6.1)?

We have a web server (IBM HTTP Server 6.1) connected using HTTPS (using SSL certificates - SSLv3) to an application server (IBM WebSphere Application Server 6.1), the application that is hosted on the app server is not upgradable, so we cannot update WebSphere on both layers to later versions.
I'm trying to enable TLS instead of SSLv3, the steps I followed:
On the web server's http.conf file, SSLv2 and SSLv3 and their cipher suites directives were removed, and TLS cipher suites were added (2F, 35b).
On the app server, QoP were changed to TLS (also tried TLSv1) instead of SSL_TLS, removed RC4 cipher suites by creating a customer list.
When opening the website URL from browser, Internal Server Error appears (means that the web is unable to communicate with the app server). When selecting the SSL_TLS again in the app server's QoP settings (keeping the SSLv2 and 3 disabled on the web server level), the website opens properly!
Is it possible the application is not compatible with TLS, pls advise?
Thank you.
The WAS Plugin tries TLS1.0 by default in 6.1.0.31 and later. To debug whatever's going on with your system, you'll have to actually watch the handshake in a packet capture and that will tell you which side to focus on.
Running 6.1 is ill advised, but running 6.1 without the latest maintenance is borderline negligent.

IIS 7.5 Secure Communication Error - The underlying connection was closed: Could not establish secure channel for SSL/TLS

We are experiencing the following error when trying to use an external web service from our application deploy under IIS 7.5.
Error - The underlying connection was closed: Could not establish secure channel for SSL/TLS.
This works from other servers, but on this particular one it fails. This started happening when the server we are trying to connect with disallowed SSL connections and is only accepting TLS. As described in this link http://support.microsoft.com/kb/915599 we changed the registry, but are still seeing the error. Please see the attached image of the registry to make sure this was done properly. It seems like IIS is still trying to use the SSL protocol. I'm a bit confused where in the communication process IIS selects the protocol, SSL vs TLS. Maybe there's something that needs to be done to ensure TLS is selected? Other ideas?
This was fixed at the code level by adding the following line -
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

An error occurred in the secure channel support - Classic ASP HTTP Request

I have a classic ASP website running on a Windows Server 2012 box. One page makes a HTTP request to another application over https using code like this:
Sub ShopXML4http(url, inStr, outStr, method, xmlerror)
Dim objhttp
Set objhttp = Server.CreateObject ("MSXML2.ServerXMLHTTP.6.0")
objHttp.open method, url, false
If Method="POST" Then
objHttp.Send instr
Else
objHttp.Send
End if
outstr=objHttp.responseText
Set objhttp=nothing
End Sub
This code works fine almost all of the time (thousands of requests per day), but sporadically it will fail with a message like this:
Number: -2147012739
Description: An error occurred in the secure channel support
Source: msxml6.dll
The application was recently moved from an old Windows 2003 Server to the 2012 Server, and this issue never seemed to be a problem on the old server. In addition, while this error is happening on the website, I could run the exact same code in a VBScript and it works fine. Resetting the application pool seems to cause the site to be able to do the secure HTTP requests again (although it often fixes itself before I can get to the server).
I have had the exact same problem after migrating from 2003 to 2008 R2 and found the solution. Change:
Set objhttp = Server.CreateObject ("MSXML2.ServerXMLHTTP.6.0")
to:
Set objhttp = Server.CreateObject ("MSXML2.XMLHTTP.6.0")
and your problem will go away.
I tried to find the pros and cons about both objects, but haven't yet found a reason to not use XMLHTTP.
I've had the same issue and tried lots of solutions offered under a variety of posts but ultimately had no success, until now. I'll detail the solution that worked for me with reference to the problem as in my case it was PayPal. I've not opened a new post as this might not be just a paypal issue in future.
The solution is a combination of a number of stackoverflow posted solutions to similar problems but this seemed the best one to add to.
The problem
Trying to test PayPal IPN on Windows Server 2008 using classic ASP using the PayPal Sandbox returns the error "An error occurred in the secure channel support".
Why it is a problem
PayPal is requiring all communications with their systems to be as secure as possible. You will need a connection that is TLS 1.2. Windows Server 2008 is not TLS 1.2 by default.
PayPal threw some confusion into the mix by saying you need a Verisign G5 certificate, which you do for the server root but not the domain you are running your code on. I also didn't install any PayPal certificates as I don't use the API. I don't believe you need your comms from an HTTPS site either - although my domain is secured using a standard GoDaddy EV cert although I did a test on a non HTTPS site after and that worked too.
My solution
First check which kind of security your server is using via SSL Labs.
It should be TLS1.2 or higher and no other TLS's or SSL's. It must also have a SHA256 encryption.
You may need to patch the server: https://support.microsoft.com/en-us/kb/3106991.
Use IISCrypto to set the correct TLS and ciphers. I used the registry changes offered up elsewhere on stackoverflow but this did not work and actually totally screwed up my server for everything using HTTPS posts, not just my development site! IISCrypto also handles the ciphers.
Make sure your application pool is v4.5, which in itself is unclear because IIS might only offer v4.0 as an option. However this is probably actually v4.5. You can verify this via https://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx.
Within your code you need to use Server.CreateObject ("MSXML2.XMLHTTP.6.0"), not Server.CreateObject ("MSXML2.ServerXMLHTTP.6.0") as mentioned above.
Now I've no idea why the non-server XMLHTTP works as that seems contrary to the documentation behind it. Right now, after 10 days of stress, panic and frustration I don't care! I hope this is useful for others.
Finding the solution was a nightmare so I'll add some phrases below to help others if searching:
PayPal IPN failing with server error
PayPal SSL Windows 2008 errors
An error occurred in the secure channel support
classic ASP PayPal Sandbox SSL errors
I'd like to publicly thank Rackspace and GoDaddy for their help with this. I'd like to publicly state that I found paypal have the worst technical support ever and just do not care, constantly pointing to their own docs, if they ever respond. They say they've been sending emails out about this since September 2014 but I never received one. These new requirements are active on the PayPal Sandbox but go live in September 2016. I only came across it as developing a new solution so needed the sandbox - if you're running live you won't know about the problem until it hits and then you're dead in the water. Test your entire payment system on the PayPal sandbox asap is my advice!!
None of the answers above applies to my situation. Then I hopped on the link here:
https://support.microsoft.com/en-za/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in
This update provides support for Transport Layer Security (TLS) 1.1 and TLS 1.2 in Windows Server 2012, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1.
Applications and services that are written by using WinHTTP for Secure Sockets Layer (SSL) connections that use the WINHTTP_OPTION_SECURE_PROTOCOLS flag can't use TLS 1.1 or TLS 1.2 protocols. This is because the definition of this flag doesn't include these applications and services.
This update adds support for DefaultSecureProtocols registry entry that allows the system administrator to specify which SSL protocols should be used when the WINHTTP_OPTION_SECURE_PROTOCOLS flag is used.
This can allow certain applications that were built to use the WinHTTP default flag to be able to leverage the newer TLS 1.2 or TLS 1.1 protocols natively without any need for updates to the application.
This is the case for some Microsoft Office applications when they open documents from a SharePoint library or a Web Folder, IP-HTTPS tunnels for DirectAccess connectivity, and other applications by using technologies such as WebClient by using WebDav, WinRM, and others.
This update will not change the behavior of applications that are manually setting the secure protocols instead of pass the default flag.
Client service on Windows 2008 R2 server outbound to server over TLS reciprocated the error in question. I thought it could be cipher suite compatibility. Wireshark trace indicated version in Client Hello request was TLS 1.0 but server requires TLS 1.2. The cipher suites sent to outbound server from client service were fine. The problem is the client service or application on Windows server default employs the system default, which is not TLS 1.2.
The solution is to add a registry subkey named DefaultSecureProtocols with a value corresponding to which TLS version(s) should be supported. Add said registry subkey, with type DWORD, to the following locations:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
For Internet Explorer fix, you can add a similar registry subkey titled SecureProtocols, also with type DWORD, to the following locations:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
Below you can find the table of values for both subkeys:
DefaultSecureProtocols Value Protocol enabled
0x00000008 Enable SSL 2.0 by default
0x00000020 Enable SSL 3.0 by default
0x00000080 Enable TLS 1.0 by default
0x00000200 Enable TLS 1.1 by default
0x00000800 Enable TLS 1.2 by default
For example:
The administrator wants to override the default values for WINHTTP_OPTION_SECURE_PROTOCOLS to specify TLS 1.1 and TLS 1.2.
Take the value for TLS 1.1 (0x00000200) and the value for TLS 1.2 (0x00000800) then add them together in calculator (in programmer mode), the resulting registry value would be 0x00000A00.
I applied 0x00000A00 as the value for both subkeys and it successfully resolved the issue.
There is also an Easy Fix (link is here: https://aka.ms/easyfix51044) available from Microsoft, if you don't wish to manually enter registry subkeys and values.
It's all valid however the 'critical' missing bit for TLS1.2 support on Windows 7 with IIS7.5 and classic asp is setting this in the registry:-
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp]
"DefaultSecureProtocols"=dword:00000800
I hope that saves you a day of faffing, rebooting and head scratching! :)
This code snippet is useful for testing. https://www.howsmyssl.com/
<%
Set winhttp = Server.CreateObject("WinHTTP.WinHTTPRequest.5.1")
winhttp.open "GET", "https://howsmyssl.com/a/check", False
winhttp.Send
Response.Write winhttp.responseText
%>
In a Windows Server 2016 Classic ASP script, fetching an HTTPS URL from Windows Server 2012 R2, I recently had to remove SSL 2.0 from SecureProtocols in order to stop this secure channel error -2147012739.
' Use the latest client
Set httpClient = Server.CreateObject("WinHttp.WinHttpRequest.5.1")
' allow only TLS 1.2 or TLS 1.1
Const WHR_SecureProtocols = 9
httpClient.Option(WHR_SecureProtocols) = &h0800 + &h0200
' Other values: TLS 1.0 &h0080, SSL 3.0 &h0020, SSL 2.0 &h0008
' NB Including SSL 2.0 stops https to Windows Server 2012 R2 working
' Other options you may want to set, from https://learn.microsoft.com/en-us/windows/desktop/winhttp/winhttprequestoption
' Ignore certificate errors
Const WHR_SslErrorIgnoreFlags = 4
httpClient.Option(WHR_SslErrorIgnoreFlags) = &h3300
' Don't bother checking cert, or risking failure if we can't check
Const WHR_EnableCertificateRevocationCheck = 18
httpClient.Option(WHR_EnableCertificateRevocationCheck) = False
Troubleshooting error codes:
-2147012739 is a HRESULT.
In hexadecimal that's 0x80072F7D.
Look at the LOWORD: 0x2F7D.
Convert that back to decimal: 12157.
Lookup 12157 error codes.
Find that it matches: ERROR_WINHTTP_SECURE_CHANNEL_ERROR
A bit of Google-fu finds http://msdn.microsoft.com/en-us/library/windows/desktop/aa383770(v=vs.85).aspx which states:
ERROR_WINHTTP_SECURE_CHANNEL_ERROR
12157
Indicates that an error occurred having to do with a secure channel (equivalent to error codes that begin with "SEC_E_" and "SEC_I_" listed in the "winerror.h" header file).
However, you already discovered this as the message you got was "Description: An error occurred in the secure channel support". So this leads us right back where we started.
The other observation I make is that your code is a non-asynchronous WinHTTP request (I know it has to be to function inside ASP), but, the concern is, due to the high frequency, your machine could be processing more than one WinHTTP request concurrently. I've seen some Windows deliberately throttle the total number of active concurrent WinHTTP request by blocking the late requests. For example, on a Windows 7 machine a process cannot make more than 2 concurrent requests to the same remote server. i.e. The 3rd, 4th... requests will be blocked until the first two complete.
One solution is to load balance incoming request over more than one application pool or over more servers.
We had a variation on this issues and it really cost us some time to figure it out.
Here is the situation: An older Linux server hosting an application written in PHP and provides data through webservice calls. The server is using HTTPS. Calls from various clients are made with code using the winHTTP 5.2 library. (Winhttp.dll)
Symptom: Our clients are now getting sporadic error messages when making repeated winHTTP calls using a ‘POST’ command. The messages are either ‘The buffers supplied to a function was to small.‘ or ‘An error occurred in the secure channel support ‘. After much searching we discovered that the client’s server was logging ‘Schannel Event ID 36887 alert code 20’ in the Event Viewer that corresponded with the visible error message.
Solution: We discovered that our old Linux server could not support TLS 1.2. (CentOS 5.11) We also learned that several of our clients had recently (summer 2016) applied an update to their Microsoft servers. (Server 2008, server 2012) The fix was to force their servers to use TLS 1.1 for the webservice calls. The part that is rather strange to me is that the settings in Internet Explorer for changing the TLS had no effect on the problem. However by changing a setting in Group Policies we were able to solve the problem. Our technical advisor on this matter pointed out that the change is really obscure, but that a third-party vendor has provided a quick solution. That tool is called IIS Crypto from Nartac. https://www.nartac.com/Products/IISCrypto/Download
The tool lets you specifically select Protocols.
We are now getting a new server to host our applications (CentOS 6) and then should be able to use the TLS 1.2 protocol!
I encountered this error a few months ago myself. Most often, this issue is caused by an invalid SSL cert. Considering that at the time of the post you had just migrated to a new server, you probably just need to reinstall the SSL certificate.
I realize this question is old, but hopefully someone else can benefit from my answer.

enabling SSL - IIS proxying weblogic server

I've enabled SSL on IIS server (running on Windows 2003) using steps mentioned here:
http://www.techpaste.com/2012/01/steps-configure-ssl-iis-windows-2003-server/
It looks like SSL is enabled properly because when I hit:
http://hostname.myhost
I get following in browser:
The page must be viewed over a secure channel The page you are trying
to access is secured with Secure Sockets Layer (SSL).
Please try the following:
Type https:// at the beginning of the address you are attempting to reach and press ENTER.
I was using this IIS as proxy to my weblogic server. All my configuration was working on HTTP (http://hostname.myhost/myapp/test.jsp).
However when I tried (HTTPS):
https://myhost/myapp/test.jsp
It doesn't work. I get following in browser:
The connection was interrupted
After googling, I found that I'll need to enable HTTPS on weblogic and I'll have to establish trust between IIS plugin and weblogic.
URL - http://docs.oracle.com/cd/E13222_01/wls/docs81/plugins/isapi.html#100382
Section: Using SSL with the Microsoft Internet Information Server Plug-In
I enabled HTTPS on weblogic by checking 'SSL Listen Port Enabled'.
Using keytool and java command, I got pem file as well for corresponding der file for corresponding certificate in DemoTrust.jks.
I added following two keys to iisproxy.ini file:
SecureProxy=ON
TrustedCAFile=c:/mycert.pem
However when I access https://hostname.myhost/myapp/test.jsp, I still get same error in browser.
In iisforward.log I see following:
Fri Aug 02 14:52:29 2013 load properties from: C:\Inetpub\WLS_IIS_Plugin\iisproxy.ini
Fri Aug 02 14:52:29 2013 WLForwardPath: /
Fri Aug 02 14:54:36 2013 TerminateFilter...
I don't see any log in iisproxy.log.
Could anyone please suggest where I am wrong?
Thanks.
Reset the iis once...
Before resetting iis the following things make sure...
you have enabled SSL port in weblogic console and make sure you have enabled that port in that server's firewall. otherwise it won't allow any outside/remote communication via that port
you have to bind an ip addess and port in IIS for ssl communication...and you must have to specify SecureProxy=ON in iisproxy.ini(the cert should be physically located..where it is specified in iisproxy.ini file like c:/mycert.pem)
