I have my website https://www.MyWebSite.com running on port 433. But I also have a admin login that only are available from the office local network http://MyServer:9999/Login.aspx. Both addresses points to the same site but different bindings.
Is it possible to get the one on port 9999 to use https? I tried creating a self signed certificate in IIS but my browser still complained, even though I exported the certificate and stored it in my CA Trusted root.
So just to sum everything:
My regular site: https://MyWebSite.com <-- working fine
My admin login, only accessible via local network: http://MyServer:9999/Login.aspx works fine.
When adding a selfsigned certificate issued to "MyServer" (not MyWebSite) and add the new binding on port 9999 I though to the website but Chrome is giving me a warning NET::ERR_CERT_COMMON_NAME_INVALID, even though the cert is Issued To MyServer and are trusted
Is it possible to get the one on port 9999 to use https?
yes it is possible to setup another port with selfsigned
certificate.
Normally Selfsigned certificate will have fully qualified machine name
e.g. machinename.subdomain.domain so you have to browse using https://machinename.subdomain.domain:9999/
Please double check what error you are running into ,In chrome
Your connection is not private
Attackers might be trying to steal your information from in08706523d (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID
in IE,you may get
There is a problem with this website’s security certificate.
The security certificate presented by this website was issued for a different website's address.
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.
In that case,assuming you have given hostname as * in IIS binding, and also installed the selfsigned certificate installed your "Root Certification Authorities " You should be able to browse to
https://machinename.subdomain.domain:9999/ without any issues

I need some direction for projects i made.
I have an existing node-red in local server that send data using websocket to my domain in my hosting. Everything is working fine over http but the problem occured when i used https for my domain. I used websocket ws: before then i changed it wss: to work over https but it still did not work because i realize i need SSL certificate for my local server too. Then, I used self-signed certificate for my local server. It works but i have to manually input my local server DDNS in my browser to allow wss first then back to my hosting domain, i can't expect the users to do this.
I used DDNS on my local server because i have no static IP. I try to call for my ISP for provide static IP but it can't be done in the near future.
Because i have no static IP i can't register domain and i can't use CA Certificate for local server SSL.
My question is:
Is there a way to allow ws to work over https?
If not, is there a way to allow unsafe wss on my domain page over a button or a prompt when user go to my page? so user don't have to manually input my local server DDNS.
Or other way you may suggest.
No, Websocket connections are bootstrapped over HTTP, Secure Websocket connections over HTTPS. The TLS session is setup by the HTTPS connection.
It's not clear what you are asking here. But the only way to get a self signed certificate to work with a websocket connection is to install that certificate into the browsers trusted certificate store before trying to access the site. The browser will not prompt to trust a certificate for a websocket connection.
You can use Letsencrypt with a proper Dynamic DNS setup. This is where you have a fixed domain name and a script on your machine that updates the IP address the domain name points at. The hostname will stay the same so the certificate issued will always have the correct CN/SAN entry. Letsencrypt certificates are signed by a trusted CA certificate that will already be present in your browser.
I have created a self-signed certificate on IIS and added it to Trusted Root Certificates using mmc.exe and when I launch my intranet using https://ipaddress shows secure. But when I go LAN and browse for the https://ipaddress shows me not trusted. I also used on IE, which I installed the certificate but still showing not trusted. Am I missing something, please help.
Self signed certificates are not trusted by browsers as the issuer (yourself) is not a trusted Certificate Authority. However, you can trust the self signed certificate if you want by adding the particular certificate to Trusted Root Certificate store. For IE, import the certificate to the Trusted Root Certificate Authorities folder in the client machine. Note that this has to be done on all client browsers/machines to trust your certificate.
Also, there could be other reasons for not trusting the certificate, please read the error description clearly.
If you use subdomain, i.e. subdomain.domain.com, the domain administrator (IT) should provide you with a wildcard certificate.
The domain administrator generates and assign the certificate to your subdomain server, also should allow port 80 and 443 firewall rules so that users can visit the site in the intranet.
The above answered methods can be used to generate the certificate, preferably sha256 certificate. Once the certificate is provided to you, install it on your server to “Personal”, “Trusted Root Certification Authorities” and “Web Hosting”. Open the certificate to validate it installed successfully, and you can use the thumbprint to sign files, such as rdp files. To do this, on your keyboard, START + R to open the run command and enter “certlm.msc” and once the window opens, navigate to “Trusted Root Certification Authorities” and there should be the certificate that was just being imported, i.e. *.domain.com, double click to open the certificate and click on Details tab. Drag the scroll bar until the Thumbprint is visible and then click on it to revel the code. Create an rdp file to your subdomain and save it to your desired location, such as desktop. Open CMD terminal and CD to the location and enter “rdpsign /sha256 thumbprint ‘./sumdomain.domain.com.rdp’”. Done, now when you open the connection, the compute should be trusted to connect to RDP, this process is not necessary, but it is nice to see the publisher is recognized.
The benefit of having the *.domain.com certificate generated for your organisation is that users should have this certificate already installed on their PCs and when they visit your website, users would automatically see the HTTPS secure padlock for SSL certificate. The certificate would usually be generated to allow all subdomains, i.e. *.domain.com.
IIS, When setting up the HTTPS binding on your IIS settings, check the "Require Server Name Indication" and continue to browse for the certificate and select and save the settings. Also turn off Directory Browsing while you’re there. Go to SSL Settings and check on Require SSL and hit Apply and go back. To control the flow of HTTP to HTTPS when users visit your site, you can use “URL Rewrite”, install it from Microsoft and you can do the configuration, please check on https://www.ssl.com/how-to/redirect-http-to-https-with-windows-iis-10/ for the appropriate settings. Even though, this answer is out of the scope for the question, it may be helpful for anyone who look forward to configuring their intranet site. Next to checkout is the security for who accesses your site, check on AppPoolIdentity, more help on IIS7 Permissions Overview - ApplicationPoolIdentity.
I am trying to create an HTTPS-tunnel on my machine. My intention is having all requests to https://localhost:8888/<something> (the port where Fiddler is listening to) be directed to https://myserver.net/<something>. I am using the following script as per Fiddler doc:
static function OnBeforeRequest(oSession: Session) {
// <Fiddler 2 preexisting code>
// HTTPS redirect -----------------------
if (oSession.HTTPMethodIs("CONNECT") &&
(oSession.PathAndQuery == "localhost:8888"))
{
oSession.PathAndQuery = "myserver.net:443";
}
if (oSession.HostnameIs("localhost"))
oSession.hostname = "myserver.net";
// --------------------------------------
// <Fiddler 2 preexisting code>
}
Also in Fiddler settings I checked the decryption check and installed certificates as you can see in the image below:
I restart Fiddler, it prompts me to install its fake certificates, I agree. I can see the certificate in my Windows Certificate System Repository when using certmgr. It is a self-signed certificate.
So What I do is opening a browser and type: https://localhost:8888/mypage.html, and what I get is an error. Internet Explorer reports this:
Error: Mismatched Address. The security certificate presented by this
website was issued for a different website's address. This problem
might indicate an attempt to fool you or intercept any data...
When I get certificate info (basically the certificate presented by the contacted host is being rejected, the same certificate can be displayed), I can see that the rejected certificate was issued by Fiddler and the subject is myserver.net.
So the certificate is ok because it is certifying myserver.net, I see that the problem is that probably my browser was expecting a certificate whose subject is localhost. Is it true?
How to handle this situation?
Assumption
I can understand that the problem is a certificate being issued for a website which I did not ask for. So the solution would be using a certificate certifying localhost:8888?
A certificate is valid if it is directly or indirectly (via intermediate certificates) signed by a trusted CA and if the hostname matches the certificate. If the last condition would not be enforced anybody with a valid certificate from a trusted CA could incorporate any other site.
To make use of fiddler and not run into this problem you should configure your browser to use fiddler as a web proxy and then use the real URL inside the browser instead of ip:port of fiddler.
I've tried setting up SSL for localhost running my azure web role.
What I've done is that I've created my own CA, created a client and server certificate and then installed them all in my certificate store. The server certificate is located in the local computer personal certificates, the client certificate is installed in the current user store under personal and the CA certificate is installed in trusted root certificates in both stores.
I've also configured my IIS website to use SSL and used netsh to bind the server certificate to the ip the site is running on.
However when I try to access my website through the IIS, I get an error:
HTTP Error 403.16 - Forbidden
Your client certificate is either not trusted or is invalid.
I know for a fact that the certificates I use are issued by the same CA, so I cant really see any other reason than that the IIS probably cant access my trusted root store. When I deploy my solution to azure, it works without giving me this error, so I'm positive that its a configuration issue with the local IIS that I cant work out.
Any suggestions on what could be the problem here?
I have a unique situation where I need to implement client certificate authentication over HTTPS between IE browser and IIS 6. The browser and IIS are separated by a firewall that only allows the browser to connect to IIS on the SSL port.
We have an internal certificate server on the same network as IIS. I've generated an SSL server cert for IIS and that is installed. I configured IIS to only allow SSL, require client certificates.
The limitation here is the browser machine is on a disconnected network, so I can't go to the CA's http://caserver/CertSrv URL and request a client cert like you normally would.
I figured if there were a way that I could generate a CSR against the Root CA's public key, I can copy it to the CA server to generate the client cert. But, there appears to be no provision in IE or the Certificates MMC to do this. The Certificates MMC seems to require a direct connection to the CA.
Has anyone solved this before?
FYI, All servers referenced run Windows Server 2003.
Update: Thanks to Jonas Oberschweiber and Mark Sutton for pointing out the CertReq.exe command line tool. Using this, I've generated a CSR, and consequently a client certificate that installs successfully. However, IE is apparently not sending this client cert when accessing the IIS server in question; it still generates a 403.7 "Forbidden: SSL client certificate is required." I suspect that the reason is that the Subject field of the client cert does not match the user id of the account running IE, thus perhaps not sending a mismatching client cert. The Subject matches that of the user I used to submit the CSR and generate the client cert on the other end of the firewall.
Does the Subject field matter? Is there something else I need to do to enable IE to send this cert?
Use the certreq command on your client as follows
certreq -new -f filein c:\certrequest.req
Here is and example of the filein
[Version]
Signature="$Windows NT$"
[NewRequest]
Subject="CN=dc1.extranet.frbrikam.com"
EncipherOnly = False
Exportable = False
KeyLength = 1024
KeySpec = 1
KeyUsage = 0xA0
MachineKeySet = True
ProviderName = "Microsoft RSA SChannel Cryptographic Provider"
ProviderType = 12
RequestType = CMC
[RequestAttributes]
CertificateTemplate=TLSServer
Replace the CertificateTemplate with the name of your certificate template
Once you have your request file you need to take it to the certificate authority on a usb stick and use the web enrolment interface as usual to process the request file.
Take the output certificate back to the client open it and click install.
You sound like you have already tried a couple of things so my guess is that you are already aware of these, but I'm going to post them anyway, just in case: Certificate Command Line Tools. I am not sure, however, if they do what you want.
Go the http://caserver/CertSrv site that you mentioned using a 3rd computer that can see the CA server. Select the 3rd option, download a CA cert, cert chai, or CRL. On the next page select 'Download CA Certificate Chain', which will download the p7b file. Using a flash drive (or email, etc) transfer this to the other computer which will allow you to import it into the trusted root servers in IE.

Suggestiong for the update, just in case - what is the trusted cert list of in the server?
Subject DN being the same as Windows username has never been a problem for me - although I don't use IIS much. However, somewhere in IIS there is sure to be a trusted certificate list. This error sounds to me like the server's trusted certs list does not include the CA or Root CA that issued the client certificate.
This is particularly true if you never get a certificate selection popup window in IE when you hit the IIS server - even though you have a certificate configured in your IE cert store. That means that the client hit the server, the server gave a list of trusted certs and the client didn't have a cert that fit the list. So the SSL session went to the Forbidden error state.
If the certificate selection window popped up, and you selected and sent the cert, there may be other configuration problems on the server side..
