Framework 3.5. According to Microsoft's official explanation, WCF (previously known as "Indigo") is a unified framework for building and running service-oriented services (oriented) applications using managed code. It enables developers to build a cross-platform, secure, trustworthy, transactional, enterprise-class interconnect application solution that works with existing systems.WCF is the integrator of Microsoft's distributed application development, which integrates.

The command code is composed of four letters, no difference Uppercase and lowercase. Because the following commands have the same effect: Mail Mail Mail Mail This is also true for tags that boot any parameter values, such as to and to. Command Code and Parameters are separated by one or more spaces. However, the parameters in the reply

Q: What is the best practice to write code to encrypt passwords? Can you provide some sample code? A: This is an interesting question: First, I want to ask why you need to implement a password encryption program, rather than letting the operating system or application manage the information. If you want to write an application that can manage the encryption code, in this regard, we generally do not put the password in the code, but use a certificate such as Kerberos ), or trust relationship in

XML security-XML attack methods you don't know The XML eXtensible Markup Language is designed to transmit and store data in various forms. Some features designed in XML, such as XML schemas (following XML Schemas specifications) and documents type definitions (DTDs), are both sources of security issues. Even though it was publicly discussed for the last decade, a large number of software still died in XML attacks. 0x00 XML Introduction XML eXtensible Markup Language, designed for data transmissi

organizations. To understand its potential, a famous Microsoft critic pointed out that "this is one of the most important contributions to computer security since the emergence of encryption technology ". In the digital world, an identity is expressed as an object (WHO), an identity requirement, and a security token (a digital representation of an object and a request ). The WCS uses self-declaration and identity hosting. A self-declared digital identity card can be used to log on to services s

Internet; in terms of host programs, it can be ASP. NET, EXE, WPF, Windows Forms, NT Service, COM + as the Host (Host ). The protocols supported by WCF include TCP, HTTP, cross-process, and custom. Security modes include SAML, Kerberos, X509, user/password, and custom. That is to say, it is easy to develop a SOA-based Distributed System under the WCF framework. Microsoft includes all the technical elements related to this, and has mastered the concep

text. For example, important information can be stolen from the message queue. 3. After a shared key is established in https, the digital signature technology is not used for message transmission, so the anti-denial capability cannot be obtained. This is indispensable in e-commerce. 4. Because HTTPS provides the security of the transport layer, it is impossible to meet the flexibility required by message security. For example, encrypt some elements in a message, encrypt different parts of the m

piece of data may arrive at multiple places, but the data should not be viewed by all recipients. Second, it provides either full or no protection. You cannot choose which part of the data to be protected. This kind of selectivity is also frequently used in WebService. The second layer protects messages. You can use the existing XML security extension standard to implement the digital signature function, so that your message is not modified by a specific party. XML file encryption technology en

You can create an authentication token and set it in the acegi security context. Because username and password authentication is performed, an instance of usernamepasswordauthenticationtoken will be created. Before creating a subject, you must specify the permissions granted to the subject. You can use the g

SSO is a very big topic. I have deep feelings about this topic. Since the establishment of the Guangzhou usergroup Forum, countless netizens have tried to use the open-source CAS, kerberos also provides another way of SSO, that is, SSO Based on Windows domains, and SAML, which has been booming since 2005.For example, there is a gap between these free SSO solutions and commercial Tivoli, SiteMinder, and RSA Secure SSO products. After all, the security

processing logic to the endpoint. This is similar to the difference between a large host and a modern distributed system architecture. In a broad sense, the most important technologies of ESB are inseparable from web services, such as WSDL (Web Service Description Language) and UDDI (Unified discovery, description, and integration) and soap (Simple Object Access Protocol). This technology is currently in a stable development stage, and the development of WS * is in an unstable process of integr

information database is not necessary. Many systems cannot store all user information in a centralized manner and user information should be stored in different storage systems, as shown in. In fact, as long as the unified authentication system and ticket are generated and verified, single-point logon can be achieved no matter where the user information is stored. 2. A unified authentication system does not mean that only a single authentication server is used. Authentication servers must excha
