Example of DES encryption implemented by JS encryption plugin CryptoJS

This article describes the DES encryption implemented by the JS encryption plugin CryptoJS. Share it for your reference, as follows:

The previous article "JS encryption plugin CryptoJS implements AES encryption operation》 introduces the simple configuration and use of the CryptoJS plug-in. Here we take a look at the method of CryptoJS implementing DES encryption:

For DES main file, comes with CBC module

For DES ECB module

Introduced using CBC mode

Introduce + using ECB mode
