## 数学代写|密码学作业代写Cryptography & Cryptanalysis代考|NET Cryptography Services

In this chapter, we will discuss the main services and cryptographic primitives that .NET Framework and .NET Core offer to professionals. Knowing what services and cryptographic primitives a development technology has to offer is very important, especially if you don’t want to develop the cryptographic algorithms and security schemes from scratch.
The following topics will be covered:

• Cryptographic primitives
• Encryption using a secret key
• Encryption using a public key
• Digital signatures
• Hash values
• Random number generation
• Support for Suite B
• Cryptography Next Generation (CHG) classes
Communication through the Internet is not inherently secure, and in this case encryption needs to be used with the goal of guaranteeing the security of such communication. The communication between these network entities is likely to be read by unauthorized third parties, or even altered. As you have seen before, the purpose of cryptography is to protect the data from being viewed or modified by parties who are not authorized to do so. With the help of the .NET Framework, we
• have cryptographic classes that are designed to be used within System. Security. Cryptography (see Chapter 9), a namespace that handles cryptography functions and their operations. Also, we are dealing with wrappers for the unmanaged CryptoAPI (Microsoft Cryptography API). Meanwhile, others are fully implemented and tested accordingly. The nice thing is that once we create a new instance of a specific encryption algorithm class, the keys are automatically generated in order to be used as easy as possible, using default properties that are very secure.

This being said, in the following sections we will provide a quick synopsis of the most important encryption algorithms that are supported by the .NET Framework (ClickOnce, Suite B, and CNG), features that were introduced starting with .NET Framework 3.5.

The encryption algorithms based on a secret key use a single secret key for the encryption and decryption processes. It is very important to guarantee the security of the key from unauthorized parties or services. Any unauthorized party that has access to the key can use it to decrypt data or encrypt other data, claiming and impersonating the real authorized party.
Encryption using a secret key is also known as symmetric encryption because the same key is used for both processes: encryption and decryption operations (see Figure 7-1). The encryption algorithms based on the secret key are very fast compared to the algorithms based on a public key. At the same time, they are most suitable for doing cryptographic encoding for large data streams. On the other hand, we have algorithms that are based on asymmetric encryption such as RSA, and their mathematical limitation is based on how much data has to be encrypted.

• 支持套件 B
• 下一代密码术 (CHG) 类
通过 Internet 进行的通信本身并不安全，在这种情况下，需要使用加密来保证此类通信的安全性。这些网络实体之间的通信很可能被未经授权的第三方读取，甚至被篡改。正如您之前所见，密码学的目的是保护数据不被未经授权的各方查看或修改。在 .NET Framework 的帮助下，我们
• 具有设计用于在 System 中使用的加密类。安全。Cryptography（见第 9 章），一个处理加密函数及其操作的命名空间。此外，我们正在处理非托管 CryptoAPI（Microsoft Cryptography API）的包装器。同时，其他的也得到了充分的实施和相应的测试。好消息是，一旦我们创建了特定加密算法类的新实例，密钥就会自动生成，以便尽可能容易地使用，使用非常安全的默认属性。
