Java & JavaScript custom encrypted data transmission code example

In the process of developing applications, the client and server often need to transmit data. When important privacy information is involved, developers will naturally think of encrypting it. Even if it is intercepted by "interested people" in the transmission process, the information will not be disclosed. Many developers have heard about encryption algorithms, such as MD5 encryption, base64 encryption, DES encryption, AES encryption, RSA encryption and so on.. Simple encryption can be performed using or, and, etc.

The ^ operation key used in the sample code is 0x01. You can customize your own rules. Define your own operations to ensure that reversible data is not lost. Key can also be defined, dynamic key.
