This is one of the simplest and most famous encryption methods.\n\n🛠️ Program functionality:\n- Text encryption using a specific key\n- Text encryption using a random key\n- Decrypting text using a specific key\n- Decrypting text using brute force (searching through all options)\n- (not yet implemented) Decrypting text using statistical text analysis\n\nSo, the program opens a text file specified by the user and performs one of the above actions with it, then a new file with the result is created in the same directory.\n\n✨ Other features:\n- SOLID principles usage\n- Design patterns usage: Factory, Command, Template method, Singleton\n- Unit testing\n\nCreated by Lev Nagornov.\n\n## Table of Contents\n\n- [Install](#install)\n- [Usage](#usage)\n- [Contributing](#contributing)\n- [License](#license)\n\n## Install\n\n1. Clone the repository using:\n\n    ```\n    git clone git@github.com:levnagornov/crypto-cli.git\n    ```\n\n2.
