There are two customer-defined methods using DES, Encrypt and Decrypt, both receive a string and return another string. Let's take a look at the details.

WebJan 18, 2024 · A Simple Crypto-Safe For Strings In C#. Encrypting a text is not enough, its integrity must also be secured. The easiest way to do this is to add a checksum to the original before encryption (and remove it again after successful decryption). If the checksum calculated after decryption does not match the decrypted one, the password is incorrect. WebIt is a console demo application, showing how to encrypt a string by using the standard AES encryption, and how to decrypt it afterwards. ( AES = Advanced Encryption Standard, a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001 which is still the de-facto ...
Web1- Stream Overview. Stream is a class that simulates a stream of bytes to be lined up in a row. Such as the transmission of data on the network, data transmited are contiguous stream of bytes from the first byte to the last byte. Stream is a base class, the other stream extend from this class.

WebThe Decorator pattern consists of the following elements: Component: This is the interface that defines operations an object can perform. The Component can be an interface or an abstract class. The Component defines an object that will be decorated. ConcreteComponent: This is the class that implements the Component interface. Web文件流和数据流 不同的流可能有不同的存储介质，比如磁盘、内存等。.NET类库中定义了一个抽象类Stream，表示对所有流的抽象，而每种具体的存储介质都可以通过Stream的派生类来实现自己的流操作。 FileStream是对文件流的具体实现。通过它可以以字节方式对流进行读写，这种方式是面向结构的 ...
WebJan 30, 2024 · Introduction. In this article, we will learn how to use the symmetric key for encrypting and decrypting data in C#.. symmetric key in C#. The symmetric key is a string used to encrypt the data, and with the exact string, we can decrypt the data, which means a single string is required for encryption and decryption.
