Caesar Messenger

** To create new chats and send messages, you need to purchase the premium subscription, without it you can only join chat rooms created by others.

---------------------------------

With this application, you can send encrypted messages to each other with your friends, try to find the keyword chosen by your friend, or try to break the special encryption method that the application has created for you by choosing higher secrecy levels. Keep in mind, higher secrecy levels encrypt each new message based on the previous message, so the app's encrypting messages will take longer each time. For this reason, you can reset the messages in the chat once in a while, or create a new chat so that you don't have to wait for hours or even days.

How chats work;
- Each chat room is for two people only. A third person can't join the room.
- The name of the chat is completely independent and can be different on each phone. Don't be surprised if your friend sees a different name when he joins the chat with the code you gave. Since your chat names and icons are stored only on your phone, you can change them as you wish, this will not affect the chat on your friend's device or the messages you send or receive.
- There are seven different secrecy levels for chats;
- Level 0: There is no encryption other than end-to-end encryption. You can use it to chat with your friend.
- Level 1: Messages are encrypted with Caesar cipher.
- Level 2: Messages are encrypted with the keyword selected in the chat settings. It is the most suitable level to find the keyword chosen by your friend.
- Level 3: Messages are encrypted with both Caesar cipher and keyword.
- Level 4-6: In addition to end-to-end encryption and keyword encryption, it uses the application's custom-created encryption methods for each chat. If you are confident in your decryption abilities, you can try these levels.
- Level 7: It uses multiple encryption methods and is the highest level of difficulty. Due to the complexity of the encryption method it uses, it may take minutes to encrypt or decrypt the message.
- If the decryption game is not fun for you, you can also use these levels for sending a secure message. The thing to remember is that when you make a change in the chat settings, it will not be transferred to the other device. It is only kept on your device. If you have changed the secrecy level, k
