There are many introductions on the DES algorithm on the Internet, with the same general idea. However, the handling of many details is not clear, and the source code quality is also uneven. For this reason, I have spent a lot of time studying it. Now I have sorted out the complete ideas and source code as follows. 1. DES algorithm introduction: The DES algorithm is also known as the American Data Encryption Standard. It is a symmetric encryption algorithm developed by IBM in 1972. Plaintext

age and so on. As you can see, the handler runs only when new data is read and knows what the data for each step is. Once a running thread has processed some of the data that is being read, the thread does not rollback the data (mostly). The following figure also illustrates this principle: Reading data from a blocked stream The implementation of a NIO is different, and here's a simple example: Copy Code code as follows: Bytebuffer buffer = bytebuffer.allocate (
