Come up with an encryption/decryption mechanism. The program runs with one of the following sets of arguments: -e fileName fileOutputName -d fileName fileOutputName where: fileName is the name of a file to be encrypted/decrypted. fileOutputName is the name of the file where you need to write the re

It's good that I remembered lesson from Java Syntax zero. You can look, on Java Syntax Zero Level 9, Lesson 6 Bitwise operations, part 2 -> 4.Encryption Rest is like always on this chapter ;)

Thank you, could not get it because, I'd skipped Bitwise lessons. 😁

If you got to this task and panicked like I did "OMG they didn't teach us anything about encryption yet" relax It's not real encryption. It would help if they said "Don't use any of Java's encryption classes. Just convert each byte to another byte, and be able to do this process in reverse."

Make sure you take "-e" and "-d" as arguments, not "e" and "d" !

To those who got confused by "encryption/decryption mechanism". You can create your own mechanism:is an encryption mechanism. The analogous decryption mechanism would be

Cool task :-) Passed for 2nd ( I should have remembered the difference between i++ and ++i :-) )

Wow, only 364 people managed to do this task by September 2020. Lowest I've seen so far! I'll leave a small hint: Caesar cipher It might look complicated to do at first, but in fact it is much easier to apply with files than with letters.

All I found on the internet was Cipher encryption/decryption and that's apparently not on the Codegym system so it can't be used. I had to use the Help section for this one. Brutal. I'm taking intro to computer science this semester at my Uni so maybe they'll brush up on this.

Important Note: For this task the args are as follows: args = -e or -d args = fileIn args = fileOut It is not all in one string that you need to split as I thought.
