Requirements Capture -Major issues to consider:
Regardless of which method of ciphering/decipheringis going to be utilized, here are the FunctionalRequirements of the system:
1-An input interface which accepts a source file, a keyword and the intended operation(Ciphering/Deciphering)
2-Outputting the file (Saving on disk) afterperforming the intended operation
Program Behavior:
java Vigenere filename.txt operation keyword
Several checks before execution:-Correct number of arguments -File existence-Operation validity-Asking whether or not the user likes to see the fileon screen before processing (In both modes ofCiphering and Deciphering)
Since each module does the opposite of the other module, eachcan be considered as the test-module of the other one.
