Mar 24, 2010  I have been asked to do a DES encryption project in C but pretty new to programming. I've found the following code in C but am not sure how to do the equivalent of classes in C. I dont know the syntax of how to move from one section of code to the next. Nov 26, 2013  Example of key generation and encryption using simplified DES. Lecture 5 of CSS322 Security and Cryptography at Sirindhorn International Institute of Technology, Thammasat University. Data Encryption Standard is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page. Demonstrate the Data Encryption Standard.
