I am currently developping a Windows 8 metro app. This app will not be available in the Martketplace but will be distributed by sideloading.
For this it is necessary to sign the app with a certificate and import the same certificate on the client machine.
I never made such a certificate? How should I proceed?
I also read the publisher name of the app should be the same as the publisher name in the certificate...
Who knows how to make such a certificate? A commercial certificate from for example Verisign is currently not an option.
If a commercial (payed for) certificate is not an option there are three other ways to get a certificate:
1) If your company has an own root certificate (trusted by a public Certificate Authority like VeriSign) you (or an admin) can derive a software signing certificate from that.
2) Your company could setup an own certificate server to issue own certificates. If the certificates are only used inside the company and the root certificate is trusted (imported in the certificate store for trusted root authorities) on all machines you could use a software signing certificate derived from the root certificate. See http://www.esecurityplanet.com/network-security/how-to-run-your-own-certificate-authority.html.
3) You could use a self signed test certificate that is not derived from a root certificate. Use makecert to create one (see How do I create a self-signed certificate for code signing on Windows?). When installing the App the user will be asked if he trusts this certificate that has no known publisher.

i builded an app running in console with Python. Then i made this app convert to exe. i wanna publish this app on the web. So i signed this app. But i see this problem:
This CA Root certificate is not trusted. Upload this certificate to the Trusted Root Certification Authorities store to be trusted.
From this warning i understand that i must my upload certificate to the Trusted Root Certification Authorities store. But i do not know it way.
My app certificate' s is:
https://www.digicert.com/support/tools/certificate-utility-for-windows
Who issued certificate:
http://127.0.0.1:5000/
Whom was issued certificate:
http://127.0.0.1:5000/
Signature algorithm:
sha256RSA
You're using self-signed certificate i.e. certificate is not issued from valid trusted Certificate Authority. If you want to publish the app for public, then you've to sign it by obtaining the certificate from valid trusted certificate authority (CA). In case, you want to manually share the app with the recipients, and they're aware of the possible risk factor then you can share the issuer certificates with them, and they've installed those into the windows trust store.
Just search for certmgr on windows and add the issuer certificates into Trusted Root Certification.
I have the company CA signed certificate, intermediate and server certificate in the identity store ( .jks) but still the browser says , cannot be verified by a trusted authority error. Using weblogic -10.3.1 from the weblogic logs i also notice this -
Invalid/unknown SSL header was received from peer x.y.z.12 during SSL handshake
But when I install the root and intermediate certificates into certmgr.msc then when i access the url again in a new window it has no error on the browser and also no error log in the weblogic server.
What could be wrong ?
Global CA's have their root and intermediates recognised by all the modern browsers. However when browser encounter s a certificate whose intermediate and roots aka chain certificates & ca certificates are not a part of its trust store so it fails to chain the leaf certificate to its issuer. So in order to mitigate thi, the roots and intermediates of the company ca must be added so that the browser can verify the complete chain.
Agreed .but thats how the trust works. The company issues ca certificate is known only to your organization but browsers are accessed globally and if you want make the certificate trusted in all the browsers then either you switch to public ca issued certificates or get your root certificate cross signed by a global ca root.
Hi I'm setting up my web site with certificate authentication. When I installed the client authentication Certificate on the server to Local Computer\Trusted Root, it get installed to Current User\Trusted Root as well. So I get 403 error.
If I delete the certificate in current user, it deletes the key in local computer as well.
Anyone has any idea?
Thank you
There are multiple issues in your case.
The behaviour you describe is by design. When you install the certificate to Local Machine store (except Personal container) are automatically propagated to all users on the system. When you delete the certificate with local administrator permissions, it is deleted from Local Machine too.
only root CA certificates should be installed in the Local Machine\Trusted Root CAs store. No personal certificates shall be installed there. These certificates are plain certificate (.cer) and used only to establish a trust to a third-party CA.
client authentication certificates MUST include private key. As per your comments, you are attempting to install .cer file which is plain public certificate without private key. There should be something with either, .pfx or .p12 file extension. These are PFX certificates with private keys.
you need to sort things out to determine what certificate types you have (end-entity or CA) and install them accordingly: CA certificates to Local Machine\Trusted Root CAs, end-entity (client authentication) to Current User\Personal (of each respective user).
I have an MVC 3 application running on IIS 7 that associates users to their client certificates during registration.
I am currently using an ECA certificate issued by ORC to login to this application locally.
I need to create self signed certificates that I can use to create new users in this application and assign to the self signed certificates.
I have created a self signed Certificate Authority Certificate. I used that certificate to sign a server and client certificate. The Certificate Authority is installed in the Trusted Root Certification Authorities of the Computer Account on the machine I'm using. The Client Certificate is installed in the Personal Store of my account.
With the above configuration, my browsers will only prompt me for the certificate issued by ORC, and not my self-signed certificate. How can I get the browser to prompt me for the self-signed certificate so that all communication with the server will use my self-signed certificate instead of the ORC issued ECA certificate?
We have an Azure web role deployed that uses HTTPS. We upload a certificate to azure and shortly after the portal refreshes and two more certificate appear. This is not a wild cart certificate and maybe this is standard behavior, but I haven't seen it before.
The original certificate is named something like:
subdomain.domain.com
The three certificates that appear are named like so:
VeriSign Class 3 Public Primary Certification Authority - G5
Class 3 Public Primary Certification Authority
VeriSign Class 3 International Server CA - G3
Are the 3 certificates I mentioned normally generated or is this an issue I should be looking into?
We have a similar deployment that has an ssl, but does not generate these extra certificates. This is what triggered our concern and has me asking why ...?
When you enabled HTTPS endpoint in any web application and bind SSL certificate to it, the certificate bind to HTTPS endpoint is could be a single certificate or it could be a chain and
it is depend on several factors as below:
When the certificate is created as self signed ROOT then it will have only one certificate in the chain. This certificate can not be validated to have SSL tunnel because there is no other part to verify it and that why it is called self signed root
When you buy certificate from a reputed CA (Certificate Authority) in almost all cases you will get 3 (or more) certificates:
2.1. Root Certificate : This certificate is helps to create a SSL tunnel between two machines using PKI security Infrastructure.
2.2. Intermediate Certificate -> This is to create a chain with multiple certs as if needed
2.3. Domain Certificate -> This is for your *.domainname.com or domainname.com
Here is an example of chained SSL certificate at https://mail.google.com
And all of these certificate are chained into one single PFX (if private key embedded into certs) or CER (without any Private Key) so when you deploy only ONE PFX cert, you see the chain is open and all certificates are listed.
If you browser your url and open the certificate view through browser, you will see exactly same chain as you could see in your portal and you can also verify the certificate thumbprint as well to match.
