Single-DES and Triple-DES encryption algorithms for general data
Using the CEX*C, you can use the triple-DES algorithm in addition to the classical single-DES algorithm.
In the subsequent descriptions of the CBC method and ANSI X9.23 method, the actions of the
Encipher and Decipher verbs encompass both single-DES and
triple-DES algorithms. The triple-DES processes are depicted in Figure 1 where
