source code analysis ). In other words, if the keys are the same, but the encryption purposes are different, the keys actually used for encryption and decryption are different. 　　 For the definition of Purpose, it can be seen from the definition that different functions, such as Forms verification, role information, and the Purpose of a series of Components in W

Event decryption and event decryption In the previous article, I wrote about delegation. I also said that delegation is the basis of many features in C #. The event to be discussed in this article is based on delegation. In C #1.0, delegation and events are the two most important features. 1. What is an event? Event design involves two types of roles: Event publisher and event subscriber. When an event occu

The use of phprsa encryption and decryption is detailed, and the use of rsa encryption and decryption is detailed. Explanation of use of phprsa encryption and decryption, and explanation of use of rsa encryption and decryption 1. the first step of encryption and decryption i

only be used within a function are called "local variables".Note: The var keyword is omitted anywhere, and the variables defined are "global variables" (which can be used outside of the function) so, in general, do not omit the var keyword.Assignment Value and assignment address:Assignment value: Used to assign a basic data type (only one value) to a variable.Reference address: Used to assign a composite data type (possibly with multiple values) to a variable. All two variables change at the sa
