Preface: After a brief introduction to the network layer protocol and HTTP protocol in the previous topic, I believe that you have a general understanding of the protocols in the network. This topic will define a Web server for the HTTP protocol,

The. NET Framework supports a wide range of databases provided by CLR. Only a small amount of code is required to implement encryption algorithms that are hard to implement in old languages such as C. This class implements some common secret

This class is summarized by referring to several documents on the Internet. It can be used directly after tests. There is a section of MD5 which should be independent of one class. I am lazy, so I wrote it into a file during the test. It still feels

A simple solution to protect the connection string Encryption By Using the winform deployed in clickonce can effectively prevent database addresses from being exposed by decompilation. A self-used multi-user invoicing project encountered the

Write Redis client by yourself (C # implementation) 2, The general form of the Redis request protocol: * cr lf $ cr lf cr lf... $ cr lf CR LF Note: CR indicates \ r; LF indicates \ n The following is an example: *3$3SET$5mykey$7myvalueRedis

Redis has adopted the new unified protocol since version 1.2 and has become the standard mode for interaction with redis server since version 2.0. The redis protocol is a compromise that balances the following requirements: Simple

In the previous blog, I mainly talked about the problems in the C # version of The gdal library. The main manifestations are:"The number of Chinese characters in the file name is an even number, which has no effect at all. Reading and creation are

The main differences are as follows: 1. The fill modes of data to be encrypted and decrypted are different. C # has the following modes: ansix923, iso10126, none, pkcs7, and zero, while Java has the following: nopadding, pkcs5padding, and
