Child Elements

None.

Parent Elements

Element	Description
<serviceCertificate>	Specifies a certificate to use when authenticating a service to the client.

Remarks

For bindings that use certificate-based message security, certificate specified by this configuration element is used to encrypt messages to the service and is expected to be used by the service for signing replies to the client. It stores a single certificate to be used when no certificate is specified by a service.

Example

The following example specifies a certificate to use for endpoints whose URI begins with http://www.contoso.com and a certificate to use for all other endpoints that do not perform certificate negotiation.

<serviceCertificate>
  <defaultCertificate findValue="www.contoso.com"
                      storeLocation="LocalMachine"
                      storeName="TrustedPeople"
                      x509FindType="FindByIssuerDistinguishedName" />
  <scopedCertificates>
    <add targetUri="http://www.contoso.com"
         findValue="www.contoso.com"
         storeLocation="LocalMachine"
         storeName="Root"
         x509FindType="FindByIssuerName" />
  </scopedCertificates>
