From a software engineer and computer scientist’s point of view, the key sections on block ciphers in this chapter of the Handbook are 7.4 DES, 7.5 FEAL, 7.6 IDEA, and 7.7 SAFER, RC5, … My original C implementations are probably from the era 1996 to 1998 of my life. In January and February of 2017 I translated the C code to C#. The results below are from the test application. I added some code on the triple-DES algorithm.
Here are the numbers from the triple DES test.
