Download or read book SYMMETRIC KEY CRYPTOGRAPHY WITH PYTHON AND TKINTER written by Vivian Siahaan and published by BALIGE PUBLISHING. This book was released on 2024-08-24 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the evolving landscape of data security, encryption algorithms play a crucial role in safeguarding sensitive information. This book delves into several prominent encryption algorithms, including AES, DES, 3DES, Blowfish, and CAST. Each algorithm offers unique strengths and is suitable for different use cases. Advanced Encryption Standard (AES) stands out for its robust security and efficiency, making it a preferred choice for many modern applications. Data Encryption Standard (DES), while historically significant, has largely been replaced by Triple DES (3DES), which enhances DES's security by applying it multiple times. Blowfish, a versatile and fast cipher, and CAST, known for its flexibility in key lengths, are also explored for their practical applications in various security scenarios. To provide a hands-on approach, this book includes detailed Python examples and Tkinter-based graphical user interfaces for each encryption algorithm. These practical examples illustrate how to implement these ciphers in real-world applications, from basic encryption and decryption processes to more complex use cases involving secure data handling and user interaction. Through these examples, readers will gain a comprehensive understanding of both the theoretical and practical aspects of encryption, empowering them to implement secure solutions tailored to their specific needs. In chapter two, we discussed the development of a Tkinter-based GUI application for AES encryption and decryption of synthetic data. The application consists of multiple tabs: one for displaying original data, one for showing encrypted data, another for decrypted data, and a fourth for entering and managing passwords. Key functionalities include generating a synthetic dataset with various attributes like UserID, Name, and Email, encrypting and decrypting this data using AES encryption in GCM mode, and displaying the results in a ttk.Treeview. The application also features password management, allowing users to set a password, generate an encryption key from it, and update the displays accordingly. The code includes several methods for data encryption and decryption, key derivation, and DataFrame management. The generate_data_intelligence_dataset method creates synthetic data, while encrypt_data and decrypt_data methods handle AES encryption and decryption. The update_displays method updates the DataFrame with encrypted and decrypted data and saves these to Excel files. The display_dataframe method dynamically displays DataFrames in the Tkinter GUI, with alternating row colors for better readability. This session detailed how each part of the code contributes to creating a rich and interactive application for handling encrypted data. In chapter three, we explored a detailed Tkinter application designed for managing and visualizing Bitcoin transaction data. The application generates synthetic data including wallet addresses, transaction types, dates, Bitcoin amounts, and their USD equivalents. Users enter an 8-byte DES key to encrypt Bitcoin amounts using DES encryption. The encrypted data is displayed in a tab within the Tkinter GUI, and users can view a histogram showing the distribution of Bitcoin amounts, both before and after encryption. The application leverages various Python libraries: tkinter for the GUI, pandas for data manipulation, Crypto.Cipher.DES for encryption, and matplotlib for plotting. Key functions include generating synthetic Bitcoin data, encrypting data with DES, and visualizing data distributions. The GUI is structured with tabs for entering the password, viewing original and encrypted data, and displaying distribution graphs. The session detailed how each function works, from generating Bitcoin addresses and transaction data to encrypting and decrypting data and plotting results. In chapter four, we discussed a Python code that integrates a Tkinter GUI with Triple DES (3DES) encryption and SQLite database management. The code encompasses the setup of an SQLite database, encryption and decryption of transaction data using 3DES, and functions for saving and retrieving encrypted transaction records. Key functions include generating a 3DES key, encrypting and decrypting data with appropriate padding, and handling database operations with retry logic to manage potential locking issues. We explored the database setup with table creation, and transaction management, and incorporated robust error handling to ensure reliable operation. The GUI implementation leverages Tkinter for user interaction and display, including functions to generate 3DES keys, handle encryption/decryption operations, and manage transaction records in an SQLite database. The session covered detailed explanations of how each part of the code operates, from database setup and key generation to data encryption/decryption and transaction storage. This comprehensive approach ensures secure handling of sensitive data and integrates encryption functionalities within a user-friendly interface, demonstrating practical applications of cryptographic techniques in a real-world scenario. In chapter five, we detailed a Python script using Tkinter for a secure cloud storage application leveraging Blowfish encryption. The script includes several core functionalities: user authentication, file upload and download, and cryptographic operations. Key aspects include helper functions for generating and verifying HMACs, as well as Blowfish encryption and decryption. The GUI is organized into tabs for user login/register, file upload, file download, and logs. Functions are defined to handle file selection, encryption, upload, HMAC generation, and downloading, ensuring that data integrity is maintained through HMAC verification and secure file handling. The Tkinter-based GUI is designed to provide a user-friendly interface for interacting with the secure cloud storage system. The SecureCloudStorageApp class initializes and configures the GUI with tabs for different functionalities. It manages user login, registration, file selection, and storage operations. The application supports encryption and decryption of files, storing encrypted data and HMACs, and provides feedback through a log and message boxes. This setup ensures secure data handling and user management, integrating cryptographic functions seamlessly into a functional application interface. In chapter six, we discussed and refined a Python script for managing file encryption and decryption using the CAST cipher, implemented with a Tkinter graphical user interface (GUI). The script includes functions for generating encryption keys, encrypting and decrypting files, and handling file uploads and downloads. It also features user authentication and registration mechanisms, utilizing bcrypt for password hashing and checking. The GUI allows users to perform these actions through a series of buttons and input fields, with status updates and error messages displayed in a scrollable text area. We further improved the script by adding error handling for file operations and ensuring proper file path management. Enhancements included better user feedback through message boxes for errors related to file reading, JSON decoding, and user actions. These improvements aimed to make the application more robust and user-friendly, ensuring reliable file management and secure encryption practices. The final version also addressed exceptions and edge cases to enhance the overall reliability and functionality of the Tkinter-based application.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2008 in the subject Computer Science - Commercial Information Technology, grade: 1.3, University of Regensburg, language: English, abstract: Cryptographic algorithms have nowadays serious impact on many fields of modern life. A good example is the SSL technology, that consists of both symmetric as well as asymmetric cryptography. It is used in thousands of websites like online banking websites to secure transfered data. For the developers of such applications the performance of employing cryptography may be a crucial factor to the success of the complete product. Normally a software developer utilizes cryptographic operations by the usage of precast cryptographic libraries. Therefore, it is interesting to analyze the speed of cryptographic libraries which implement abstract cryptographic algorithms. In the following, we describe our benchmarking of various cryptoalgorithms in different cryptolibraries in different languages on a 32-bit system. In the first part, we outline our preparatory work and our considerations on setting up a fitting benchmarking environment. With this test environment we conducted the benchmarking of seven JAVA cryptolibraries, namely SUN-JCE, Flexiprovider, Bouncy Castle, Cryptix Crypto, IAIK-JCE, GNU crypto and RSA JSafe. Additionally, we benchmarked RSA BSafe, a cryptographic library, which is written in C++, to isolate the influence of the JAVA virtual machine abstraction layer on cryptographic performance. In the second part, we present a condensed illustration of the benchmarking results and our interpretation, for symmetric cryptography, asymmetric cryptography, the generation of hash based massage authentication codes and digital signatures. These results reveal remarkable differences in speed between the algorithms as well as between the different implementations. Also the choice of the underlying operating system has influence on the execution speed of the cryptographic code. In this work we demonstrated
