Two cryptography algorithms DES(Not 3DES) and AES algorithms should be implemented in four modes Electronic Code Book(ECB), Cipher block Chaining(CBC),Output feedback mode(OFB), Counter Mode(CTR). Initially when executing program the user gives message from the command prompt [url removed, login to view] program should allow the user to select one of the two algorithms and after selecting it should ask for the mode. Then for the given input message it should give the Encrypted and decrypted message. Key is randomly generated by the program.
1) No need of GUI.
2) InitializationVector(IV) is also randomly generated by program.
3) Cryptography related libraries can't used as the user need to change the S-BOX values
