However, it is a smaller algorithm and has fewer parameters than DES.\n\n- It is a **block cipher** that operates on an **8-bit input**.\n- Being a symmetric key cipher, it uses the same key for both encryption and decryption. A random **10-bit key** is used to produce **two 8-bit keys** which will in turn, be used for encryption and decryption.\n- It uses both, **substitution** and **diffusion**, just like DES.\n\nInstall all packages \u003cbr\u003e\n**`npm install`** \n\nRun the app \u003cbr\u003e\n**`npm start`**\n\u003cbr\u003e\n\n| **Key Generation** | ![Key Generation](assets/key_gen.png) |\n:-------------------------:|:-------------------------:\n\n| | Encryption          |  Decryption |\n:-------------------------:|:-------------------------:|:-------------------------:\nIteration #1    |  ![Encryption (Iteration #1)](assets/enc_1.png)  |  ![Decryption (Iteration #1)](assets/dec_1.png)\nIteration #2    |  ![Encryption (Iteration #2)](assets/enc_2.png)  |  ![Decryption (Iteration #2)](assets/dec_2.png)\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsaharshleo%2Fs-des","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsaharshleo%2Fs-des","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsaharshleo%2Fs-des/lists"}
