When creating chat

• Codename of chat: used for syncing, and sorting chats
• Password for online syncing: this password will be used to decrypt/encrypt new messages on clients (messenger). This password must be shared to read new messages (if using mode Sync)
• Password for local chat: uses for decrypting local chat. Only for safety about info ({chat name}/chat.smoc file)

How chat work

1. Message encrypts (in this format {username}: {message itself}) in Fernet, using internal library "smessage"
2. Then, client connects to the server by entered data, then executes ~/SMOC-Server/server.py (using python) with args "send"
3. On server, it writes encrypted message by this form SMOC-Server/main/{codename of chat}.{username supposed to read}
4. When another client, syncing chat, by it settings connects to server, executes server.py and checks if there's any messages unread by {codename}.{username}
5. If client finds there's a unread one, it will decrypt it, then put into local chat
