Bug Experience:Passwords are stored in the database after encryption with MD5, because the length of the password field is set too small (Eg:varchar (30)), causing the database to store only a portion of the MD5 encrypted results, resulting in the login is not up, the length of the password field is expanded (eg: varchar (100)), to update the database results, you can log in.

In TCPsocket communication, how does one use ssl encryption technology to encrypt and decrypt data packets? -- Linux general technology-Linux technology and application information. For details, refer to the following section. C language in linux. May I ask, When the client wants the server to send data packets, it needs to use ssl to encrypt the

When communicating with the client and the server, there is a common scenario that is passed back and forth through an ID as a URL parameter. Assuming that there is only this ID identified in the business, then a slightly more secure communication is required, and the ID is encrypted and transmitted to the server for decryption. This requires a confidential key from the server, which is used to encrypt and decrypt the key.The decryption method is as follows: $str is a string that needs to be dec

In unity, you can use the c # built-in symmetric algorithm to encrypt data.
