Enigma

Description

Diagram of project’s main functionality -- reading text from standard input, processing it (enciphering/deciphering) and printing the result to standard output:

This requires implementing:

• Enigma Services - implementations of chosen ciphers (http://practicalcryptography.com/ciphers/ or any other)
• Application itself: skeleton responsible for initializing all the other components, parsing command line arguments etc.
• Terminal Translator - a module responsible for the main functionality: reading text from standard input, processing it (enciphering/deciphering) and printing to standard output
• Service Repository to provide our application and its modules with implementations of EnigmaService

The program’s used should be as shown below:

• java engima.Application -e | -d (enciper/decipher) CIPHER [KEY]

• To start it in encrypting mode use -e option; -d to start in decrypting mode
• CIPHER says what kind of cipher we want to use and KEY is the optional KEY to be used with the CIPHER (if selected cipher requires a key)
• The program should take every line (a string of characters) from standard input and process it according to the options used. The result should be printed to the standard output.
• The user should be able to list all available (implemented) ciphers using -l option

• java enigma.Application -l
