I have an Azure Function calling an HTTPS endpoint using an SSL certificate that was provided by an internal Root CA.
Without doing anything, I have an SSL negotiation error which is normal.
I added the ROOT CA cert in the SSL Settings of my Function App, and I also added the setting WEBSITE_LOAD_ROOT_CERTIFICATES in the Function App Settings.
By using the Kudu Console, I tried to curl my HTTPS endpoint, and I'm still having SSL troubles.
Am I missing something?
You can't use an internal authority signed certificate against an Azure Function that is in a multi-tenant environment. The only available approach is to use App Service Environment (ASE). Using ASE, will enable you to upload an issuing and root certificates that are signed by a private/internal authority and register them in the store to be able to be interrogated.
Try to follow the below steps to enable SSL.
Go to App service and then select TLS/SSL settings.
Click on Private Key Certificates and then click on Create App Service Managed Certificate. It opens a side window in that window click on create button.
After successfully created, go to custom domains and click on Add binding.
Under TLS/SSL binding, select custom domain name, private certificate thumbprint, and its type then click on Add Binding.
Once we finished the above steps then it will add to your domain.
As per the Microsoft Document, Add a TLS/SSL certificate in Azure App Service.

I have created an asp.net web application and deployed it in IIS10. The design of the application is to require a client certificate for each user which will be provided by us. For testing purposes I created a self-signed certificate using the makecert.exe and followed the instructions at https://blog.jayway.com/2014/10/27/configure-iis-to-use-your-self-signed-certificates-with-your-application/. I added the certificate in the MMC Personal Certificates.
I also configured the iisClientCertificateMappingAuthentication in the IIS Configuration Editor using the one-to-one mapping approach. When I tested it on the browser, at first it asked for a digital certificate (which is correct), but when I clicked the certificate I added on the bindings it returns an error "Your client certificate is either not trusted or is invalid."
What should be the problem here since the installed client certificate is already added in the IIS one to one mapping configuration? Do I need additional configuration in the IIS?
Say, for example, I have an Azure web app named MyApp and is hosted on Azure as MyApp.azurewebsites.net. It's my understanding that there is nothing I need to do to secure the URL with SSL, as it's done, by default, with a single certificate. So I can already have my users access the app via https://MyApp.azurewebsites.net, and it will be secure right out of the box.
However, say I have another URL named www.MyApp.com that I want to point (redirect) to https://MyApp.azurewebsite.net. Do I have to secure www.MyApp.com with a certificate?
Do I have to secure www.MyApp.com with a certificate?
Yes, we could get more detail info from the official document .
To secure your custom domain name with HTTPS, you bind a custom SSL certificate to that custom domain in Azure.
Before binding a custom certificate, we need to do the following:
Configure the custom domain - App Service only allows adding a certificate for a domain name that's already configured in your app. For instructions, see Map a custom domain name to an Azure app.
Scale up to Basic tier or higher App Service plans in lower pricing tiers don't support custom SSL certificates. For instructions, see Scale up an app in Azure.
Get an SSL certificate - If you do not already have one, you need to get one from a trusted certificate authority (CA).
Yes, if you use a custom host name, then you will need to have a certificate for it. There is really no way around this, based on how SSL works.
I have two client certificates that I have installed for my API project in the Azure portal. I have set the config option to enable them and can verify that they can both be found in the CurrentUser 'My' store. My problem is now that one of them is failing validation. On my local machine I have this cert installed in the Trusted People store of LocalMachine. Is there anything I can with Azure to make this work?
Is the location of the cert the issue or is it possibly something with the certificate itself?
**Note that this is an app service, not a cloud service
There are few things you can check, In Azure check in the app settings whether you have added your certificate. Its in the SSL section of you Azure app.
Another workaround would be where you are configuring your Token Authentication, you could set this settings.
For e.g. In my case, I was getting X509 Certificate error.
I added this code in my project.
System.IdentityModel.Configuration.IdentityConfiguration config = new System.IdentityModel.Configuration.IdentityConfiguration();
config.CertificateValidator = X509CertificateValidator.None;
config.CertificateValidationMode = X509CertificateValidationMode.None;
Basically turn off your validation. Most of the times, what happens is your local machine as all the certificates installed by an IT Operation person, but Those certificates are not on Azure.
You can check here for some reference as well. Microsoft Certificate Reference
I have a client site that when a button is clicked it calls a wcf web service. The client site is http, while the url for the web service is https and requires a certificate. I have a valid signed private key certificate I am using.
Everything works fine on my localhost; however, after deploying to a windows 2003 server running iis 6, I get the below error when the web service is called:
Could not establish trust relationship for the SSL/TLS secure channel
with authority "host's url"
I added the cert to the store, using same web.config that works locally. I have validated that the web service call finds and sets the valid X509Certificate.
Not sure what I am missing, and I don't want to override the servicepiont manager to return true every time.
Any ideas or things I might looks into?
Found the problem.
The root certificate which the host of the web service uses was not trusted by my server. (not sure why it was on my local machine and not my server). I found this out by opening the host's url in a web browser from the server to view their wsdl and got the security warning.
Remedy: went to the issuer's site downloaded their root cert and added to my trusted root certifcation authorities.
Bam, it works now.
If it is a private cert it must be added to both the client and the server as no client can validate its root key.
I working to develop small HTTPS server that will be included in my android application. And the client will be browser. User can browse to the contain that I have on my HTTPS server. Can someone tell me what kind of setup do I need as far as the certificate and private/public keys are concerned. I am planning to use openssl to create my self-signed certificate.
FYI, I have initial setup done. And since my certificate is self-signed, browser displays warning to accept it on your own risk. So I believe server authentication is working. What do I need for server to authenticate the client ?
Thanks
The problem with hosting an HTTPS webserver on an android device is that the certificates are validated using a domain name. Without a domain name the client browser will display an error unless the server certificate is installed and trusted locally.
The two options are:
Register a domain name, use dynamic dns, and then request an ssl/tls certificate based on that name.
Installing self-signed certificate programmatically
There is an Android library that supports https: http://tjws.sourceforge.net/
