This wordle game ... doesn't quite work yet! The code in main.py is fine, but none of the functions or classes in the wordle module have been implemented ...
To make it work, complete the tasks below.
wordle.is_five_letters() and wordle.is_valid_word()

| """Creating an Asymmetric Key Pair | |
| <IN SYLLABUS> | |
| Anybody can create a public-private key pair! | |
| A key pair comprises two parts. Typically, one part is kept secret (the private | |
| key) while the other part is published publicly to enable anybody to access it | |
| (the public key). | |
| Either key can be used to encrypt; the encrypted message can only be decrypted | |
| using the other key. | |
| This kind of encryption is known as *asymmetric encryption*, vs symmetric |
| """Let's get our very own digital certificate! | |
| We could create a self-signed certificate, which means there is no | |
| cert authority (CA), but that wouldn't be trustworthy. It's only useful for | |
| sending encrypted data between machines we own (since we trust our own cert). | |
| Unfortunately, most cert authorities (CA) charge a fee for a certificate (and | |
| the service of verifying it, and making your public key available). | |
| There is one that doesn't: [LetsEncrypt](https://letsencrypt.org/). Let's | |
| request a certificate from them. | |
| LetsEncrypt uses the Automatic Certificate Management Environment (ACME) | |
| protocol to automate the process, which is nice because it means we can write |
| """Creating a Digital Signature | |
| <IN SYLLABUS> | |
| A digital signature verifies the authenticity of a digital message. | |
| ## Creating a digital signature | |
| 1. The message is hashed (using a cryptographic hash function). | |
| 2. The message hash is encrypted with the sender’s private key to produce a digital signature. | |

Socket programming allows developers to build these kinds of network applications by using programming languages like Python, C, or Java to create, connect, and manage sockets. A network socket is an endpoint for sending or receiving data across a computer network, and it forms the foundation of communication in the TCP/IP stack. When two devices want to communicate, each creates a socket—one to listen for incoming connections (server) and one to initiate the connection (client).
Each socket is defined by a combination of an IP address and a port number. Using sockets, programs can send and receive streams of data over the internet or a local network, whether it's for browsing the web, sending emails, or chatting in real time.

The process of converting an object to text data is known as serialisation.
The process of converting text data to an object is known as deserialisation.
In Python, we can manually serialise or deserialise data using IOStream objects.
The simplest way to get an IOStream object is to use the built-in open() function.
>>> f = open('test.txt', 'w')
>>> type(f)
