How to: Secure a Service with an X.509 Certificate
X certificates are digital documents that represent a user, computer, service, or device. They are issued by a certification authority (CA), subordinate CA, or registration authority and contain the public key of the certificate subject. They do not contain the . Use X certificates with a group enrollment in a production environment. In a group enrollment, you add a root or intermediate X certificate to your IoT Central application. Devices with leaf certificates derived from the root or intermediate certificate can connect to your application. Generate root and device cert.
This topic hpw how to configure Windows Communication Foundation WCF to use different certificates for message signing and encryption on both the client and service. To enable separate certificates to be used for signing and encryption, a custom client or service credentials or both must be created because WCF does not provide an API to set multiple client or service certificates.
Additionally, a uze token manager must be provided to leverage the multiple certificates' information and to create an appropriate security token provider for specified key usage and message direction. The following diagram shows the main classes used, the classes they inherit from shown by an upward-pointing arrowand the return types of certain methods and properties. MyClientCredentials is a custom implementation of ClientCredentials.
Its properties shown in the diagram all return instances of XCertificate2. In addition, you must create a custom identity verifier, and link it to a security binding element certificatw a custom binding. You must also use the custom credentials instead of the default ude. The following what is a clinical nurse shows the classes involved in the custom binding, and how the custom identity cegtificate is linked.
There are several binding elements involved, all of which inherit from BindingElement. Define a new certiricate credentials class that inherits from the ClientCredentials class.
Also override the How to use x.509 certificate method to return an instance of the customized ClientCredentialsSecurityTokenManager class that is defined sue the next step. Define a new client security token manager that inherits from the ClientCredentialsSecurityTokenManager class. Override the CreateSecurityTokenProvider method to create an appropriate security token provider.
The requirement parameter a SecurityTokenRequirement provides the message direction and key usage. Define a new service credentials certivicate that inherits from the ServiceCredentials class.
Also override the CreateSecurityTokenManager method to return an instance of the customized ServiceCredentialsSecurityTokenManager class that is defined in the next step. Define a new service security token manager that inherits from the ServiceCredentialsSecurityTokenManager class. Override the CreateSecurityTokenProvider method to create an appropriate security token provider given the passed-in .x509 direction and key usage.
Create a custom binding. The security binding element must operate in duplex mode to allow different security token providers to be present for requests and responses. One way to do this is to use a duplex-capable transport or to use the CompositeDuplexBindingElement as shown how long does temazepam take to work the following code. Link the customized Certificcate which is defined in the next step to the security binding element.
Replace the default client credentials with the customized client credentials previously created. Define a custom IdentityVerifier. The service has multiple identities because different certificates are used to encrypt the request and to sign the response. In the following sample, the provided custom identity verifier how long to cure alcoholic fatty liver not perform any endpoint identity checking for demonstration purposes.
Cdrtificate is not recommended practice for production code. The security binding element must operate in a duplex mode to allow different security token providers to be present for requests and responses.
As with the client, use a duplex-capable transport or use CompositeDuplexBindingElement as shown in the following code. Replace the default service credentials with the customized service credentials previously created. Skip to main content. Contents Exit focus mode. How to: Use Separate X. Note In the following sample, the provided custom identity verifier does not perform any endpoint identity checking for demonstration purposes.

Use the SetCertificate method of the XCertificateRecipientServiceCredential class to add the valid certificate to the service. The method can use one of several methods to find a certificate. This example uses the FindBySubjectName enumeration. For authentication, choose X CA Signed. Run./rkslogadoboj.com create_device_certificate mydevice to create a new device certificate. This creates two files named rkslogadoboj.com and rkslogadoboj.com files in your working directory. Step 5 - Test your device certificate. To use multiple certificates on the service. Create a custom binding. The security binding element must operate in a duplex mode to allow different security token providers to be present for requests and responses. As with the client, use a duplex-capable transport or use CompositeDuplexBindingElement as shown in the following code. Replace the.
Securing a service with an X. This topic walks through the steps of configuring a self-hosted service with an X. A prerequisite is a valid certificate that can be used to authenticate the server. The certificate must be issued to the server by a trusted certificate authority. If the certificate is not valid, any client trying to use the service will not trust the service, and consequently no connection will be made. For more information about using certificates, see Working with Certificates.
Create the service contract and the implemented service. For more information, see Designing and Implementing Services. Create an instance of the WSHttpBinding class and set its security mode to Message , as shown in the following code. Create two Type variables, one each for the contract type and the implemented contract, as shown in the following code.
Create an instance of the Uri class for the base address of the service. Create a new instance of the ServiceHost class with the implemented contract type variable and the URI.
Pass the contract, binding, and an endpoint address to the constructor, as shown in the following code. To retrieve metadata from the service, create a new ServiceMetadataBehavior object and set the HttpGetEnabled property to true.
The method can use one of several methods to find a certificate. This example uses the FindBySubjectName enumeration. The enumeration specifies that the supplied value is the name of the entity that the certificate was issued to. Call the Open method to start the service listening. If you are creating a console application, call the ReadLine method to keep the service in the listening state.
The following example uses the SetCertificate method to configure a service with an X. Skip to main content. Contents Exit focus mode. How to: Secure a Service with an X. Is this page helpful? Yes No. Any additional feedback? Skip Submit.
