Cryptography certificate verification Unable to verify certificate chain. I am using X509Certificate' verify method to verify certificates but is throwing error "The also the publication and management of public-keys. The standard mechanism to achieve this is digital certification. This part of the article discusses digital certificates and their implementation in FCL and Web Service Enhancements (WSE 1.0) for Microsoft NET. It also digresses into Windows 2000 PKI. Digital Certification Digital certification is an application in which a certification authority signs a special message m, containing other than the centralized certification authority. This message m along with its signature is called digital certificate or digital id. A typical digital certificate contains the subjects name, subjects public-key, subjects

X.509 Certificate Authentication and Digital Signature of SOAP Messages with WSE Using Web Services Enhancements (WSE) for X.509 Certificate Authentication and Digital Signature By Peter A. Bromberg, Ph.D. Printer - Friendly Version Peter Bromberg In the first how to use the Web Services Enhancements Toolkit to perform SHA1 Digest hashed username / password authentication with the IPasswordProvider interface, using a modified version of the Northwind Database Employees table to do our username / password authentication with the UsernameToken element. Besides UsernameTokens, the WS-Security specification also defines the BinarySecurityToken element

How to generate and use certificate for https request Please suggest the steps used in sending https request with certificate , i am using http listner which can send the https request . you just preface the ssh_test_certificate.html Refer: http: / / www.codeproject.com / KB / WCF / wcfcertificates.aspx Implementation details Loading a certificate from a file is quite easy, you must simply use the System.Security.Cryptography.X509Certificates.X509Certificate2 class : Collapse Copy Code / / Load the certificate from a file X509Certificate2 certificate = new X509Certificate2(fullpath, password); The first parameter is the path of the certificate file, the second parameter is the password used to encrypt the private key ( if present exe, both available as Visual Studio Tools. Here an example on how to create a certificate: Collapse Copy Code makecert -r -pe -n "CN = CompanyXYZ Server" -b 01 / 01 / 2007 -e makecert and pvk2pfx, you can insert a password used to encrypt the private key. Service authentication This section describes how to configure the server with the certificate used to authenticate the

I was sent a specification for the Xml Signature handshake process, along with a sample certificate, and asked to come up with the code that would enable them to perform a modified Xml Signature on a user token, using the private key from their certificate, and POST the small Xml document to the provider's server, which would use the especially, the new Web Services Enhancements (WSE) classes, to enable the client to retrieve a certificate from his local machine user store, use it to sign the specified Xml Element and build a Winforms helper utility that can be used to retrieve a specific X.509 certificate from the local machine user store by subject search string, load an Xml template document containing a particular XmlElement that needs to be digitally signed, and use the certificate's private key to create the final document that will be used in the successful implementation of Xml Signature, I simply couldn't find one that retrieves and uses a CERTIFICATE in order to perform the signature process (DUH? - isn't that what people would normally objectives in accomplishing this overall process: 1.) We need to be able to install the certificate on the client machine, in the correct store. 2) We need to be able to retrieve this particular certificate via some sort of search faciilty so that we can use it. 3) We need

Username / Password Authentication of SOAP Messages with WSE Using Web Services Enhancements (WSE) for Username / Password Authentication By Peter A. Bromberg, Ph.D. Printer - Friendly Version Peter Bromberg The WS-Security specification some gaping deficiencies in the web services problem domain, namely, the ability to handle security, authentication, encryption, digital signature, routing and attachments at the message level , rather than using out of band or my own sample implementation that will take you through the process of implementing username / password authentication with the WSE. You'll be taken step-by-step through the process and the reference to the Microsoft.Web.Services.dll in the project. That's normally located at: C: \ Program Files \ Microsoft WSE \ v1.0.2312 \ Microsoft.Web.Services.dll In order to validate user. The idea is that in this method, you are free to implement whatever custom authentication scheme you want to use for the web service. In this example, we'll use of the UsernameToken object, we can't use the LogonUser API directly for custom Windows Authentication without employing the clear text username / password option. Normally this would simply require that we
