How to understand the application of hash algorithm in C # encryption? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Hash algorithm is often used in C # encryption, so what is hash algorithm? How is its function realized? Here we will introduce the implementation process in detail. Before learning, we need to understand that there are many ways to create hash codes. In fact, even the same hash algorithm can be implemented through many classes. Take SHA1 as an example:

An implementation example of hash algorithm in C# encryption:

String plaintext = "plaintext"; byte [] srcBuffer = System.Text.Encoding.UTF8.GetBytes (plaintext); HashAlgorithm hash = HashAlgorithm.Create ("SHA1"); / / change the parameter to "MD5", then MD5 encryption is performed. Case insensitive. Byte [] destBuffer = hash.ComputeHash (srcBuffer); string hashedText = BitConverter.ToString (destBuffer) .replace ("-", ")

You are using the class HashAlgorithm, whose namespace is System.Security.Cryptography. Only two of its methods are used: Create and ComputeHash,ComputeHash return byte [], and in order to show that this is converted to a string, after conversion, it is the same as the SHA1 result in the previous section.

You can also use SHA1Managed and SHA1CryptoServiceProvider, but we recommend the method in this article because it does not involve class names, and to change the algorithm, you only need to change the string parameters of Create.

This is the answer to the question on how to understand the application of hash algorithm in C# encryption. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
