The. NET core of Des and other encryption algorithms to wait until 1.2 to support, we urgently need the support of this algorithm, the article "Using Javascriptservice in. NET core implementation des encryption algorithm" needs to use Nodejs, many people think this is a little bad, Today we will introduce the Bouncycas

As a web front-end application, communication with the server or back-end communication, as well as the transfer of data between different users, in some specific cases need to encrypt some information transmission, in an event to remove information and decryption, get the correct information. Looking at different languages and different algorithms, there are many options. Today, from the most basic encryption and decryption algorithm
