It is a symmetric key algorithm, which means that the same key is used for encrypting and decrypting ​data. Encryption and decryption using the DES algorithm.\n\n## Table of Contents\n\n- [DES Algorithm](#des-algorithm)\n  - [Table of Contents](#table-of-contents)\n  - [Installation](#installation)\n  - [Usage](#usage)\n  - [Group Details](#group-details)\n\n## Installation\n\n1.
