This book was released on 2024-08-28 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlock the secrets of modern cryptography explored in this book, a comprehensive guide that takes you from the fundamentals to advanced applications in encryption, decryption, and digital signatures. Whether you're a beginner or an experienced developer, this book offers hands-on examples, real-world scenarios, and detailed explanations that make complex concepts accessible and engaging. Dive into the world of RSA, as you learn to build secure systems and protect sensitive information with confidence. Perfect for anyone looking to master the art of cryptography, this book is your key to the future of digital security. In chapter one, we implemented RSA key generation within a Tkinter-based GUI application. This example was designed to be user-friendly, allowing users to generate RSA keys with a simple button click. The process involved generating a private key and a corresponding public key, which were then displayed within a text widget for easy copying and saving. This example demonstrated the ease with which RSA keys can be generated programmatically, making cryptography more accessible to users who may not be familiar with command-line interfaces. In chapter two, we embarked on a journey to create a sophisticated RSA encryption and decryption project. We began by constructing a comprehensive Tkinter-based GUI application that allows users to generate RSA key pairs, create and sign transactions, verify signatures, and securely store transactions. The initial focus was on setting up the graphical user interface, with multiple tabs dedicated to different functionalities, ensuring that the application was both user-friendly and feature-rich. The core functionality of the application revolves around RSA key generation, transaction creation, and digital signing. The RSA keys are generated using the cryptography library, and users can generate private and public keys, which are then displayed in the application. This setup forms the foundation for securely signing transactions. The transaction creation process involves entering details like the sender, receiver, amount, and currency, after which the transaction data is signed using the private key, producing a digital signature. This digital signature ensures the authenticity and integrity of the transaction, preventing any tampering or forgery. Once transactions are signed, they can be stored in a secure manner. The application allows users to save these transactions, along with their digital signatures, in a JSON file, providing a permanent and verifiable record. This storage mechanism is crucial for maintaining the integrity of financial transactions or any sensitive data, as it ensures that each transaction is accompanied by a corresponding signature and public key, enabling later verification. The verification process is another key component of the project. The application retrieves stored transactions and verifies the digital signature against the stored public key. This process ensures that the transaction has not been altered since it was signed, confirming its authenticity. The verification feature is critical in real-world applications, where data integrity and authenticity are paramount, such as in financial systems, legal documents, or secure communications. Throughout the chapter, the project was designed with a strong emphasis on real-world applicability, robustness, and security. The example provided not only serves as a practical guide for implementing RSA encryption and decryption with digital signatures but also highlights the importance of secure key management, transaction integrity, and data authenticity in modern cryptographic applications. This project demonstrates the power of RSA in securing sensitive data and transactions in a user-friendly and accessible way, making it an essential tool for developers working with encryption in real-world scenarios. In chapter three, we some projects focused on RSA digital signatures, delving into the creation of synthetic datasets, key generation, data signing, and verification processes. The project’s primary objective is to demonstrate how RSA digital signatures can be applied in a real-world scenario by securely signing and verifying user data. This example uses a synthetic dataset of user information, including user IDs, names, emails, and registration dates, to illustrate the practical implementation of RSA cryptography. The project begins with generating RSA keys using the generate_rsa_keys function. This function creates a pair of keys: a private key used for signing data and a public key for verifying the signature. These keys are essential for the RSA cryptographic process, where the private key ensures that the data remains authentic and unaltered, while the public key is used to verify the authenticity of the signed data. The keys are serialized into PEM format, a widely-used encoding standard that facilitates the secure storage and transmission of cryptographic keys. Next, a synthetic user dataset is generated using the create_synthetic_user_dataset function. This dataset comprises a specified number of user records, each containing a unique user ID, name, email address, and registration date. The purpose of this synthetic data is to simulate a realistic environment where user information needs to be securely signed and verified. By using a synthetic dataset, we ensure that the example remains versatile and adaptable to various scenarios without relying on actual sensitive information. Once the dataset is generated, the sign_data function is employed to sign each user's data using the RSA private key. This process involves creating a digital signature for each record, ensuring that any alteration to the data after signing would invalidate the signature. The digital signature serves as a cryptographic proof of the data’s integrity and authenticity, providing a robust mechanism to detect tampering or unauthorized modifications. The signatures are then stored alongside the user data for subsequent verification. Finally, the project includes a mechanism for storing the signed data and public key in a JSON file, and a function for retrieving and verifying the data. The store_user_data function saves the user data, corresponding signatures, and the public key to a file, allowing for secure storage and later retrieval. The retrieve_and_verify_user_data function reads the stored data, verifies each signature using the public key, and confirms whether the data remains unaltered. This final step completes the demonstration of how RSA digital signatures can be effectively used to secure user data, making it a comprehensive example for those learning about cryptographic techniques in real-world applications.

Available in PDF, EPUB and Kindle. Book excerpt: Project 1 demonstrates generating a DSA (Digital Signature Algorithm) key pair using the cryptography library, where a 2048-bit private key is created and a corresponding public key is derived. The private key is essential for securely signing digital messages, and the public key allows others to verify these signatures. Both keys are serialized into PEM format, making them suitable for storage or transmission. The private key is serialized without encryption (though encryption is optional), while the public key is also serialized for easy sharing and use in cryptographic operations. Project 2 is a DSA (Digital Signature Algorithm) Key Generator application built with Python's tkinter for the GUI and the cryptography library for key generation. It provides an intuitive interface to generate, view, and save 2048-bit DSA key pairs, essential for secure digital signatures. The GUI features two tabs: "Generate Keys" for creating and serializing keys into PEM format, and "View Keys" for displaying them. Users can save the keys as .pem files with ease, supported by robust error handling and success notifications, making the application accessible and practical for secure communication needs. Project 3 demonstrates the process of signing and verifying a message using the Digital Signature Algorithm (DSA) in Python, while ensuring the signature is UTF-8 safe by encoding it in Base64. It begins by generating a DSA private and public key pair with a key size of 2048 bits. A message (in bytes) is then created, which is the data to be signed. The private key is used to generate a digital signature for the message using the SHA-256 hashing algorithm, ensuring the integrity and authenticity of the message. The generated signature, which is binary data, is encoded into Base64 format to make it text-safe and suitable for UTF-8 encoding. To verify the signature, the Base64-encoded signature is first decoded back into its original binary form. The public key is then used to verify the authenticity of the signature by comparing it to the message. If the verification is successful, the message "Signature is valid." is printed; otherwise, an InvalidSignature exception is raised, and the message "Signature is invalid." is displayed. This approach ensures that the digital signature can be safely transmitted or stored as text without data corruption, while still preserving its security properties. Project 4 is a Tkinter-based GUI application for Digital Signature Algorithm (DSA) operations, offering an intuitive interface for generating DSA keys, signing messages, and verifying signatures. It has two main tabs: one for generating and displaying DSA key pairs in PEM format, and another for signing and verifying messages. Users can input a message, sign it with the private key, and view the Base64-encoded signature, or verify a signature against the original message using the public key. The application handles errors gracefully, providing feedback on operations, making it a practical tool for cryptographic tasks. Project 5 and 6 provides a complete implementation for generating, signing, and verifying files using the Digital Signature Algorithm (DSA). It includes functions for creating DSA key pairs, signing file contents, and verifying signatures. The generate_and_save_keys() function generates a private and public key, serializes them to PEM format, and saves them to files. The sign_file() function uses the private key to sign the SHA-256 hash of a file's content, saving the signature in Base64 format. The verify_file_signature() function then verifies this signature using the public key, ensuring the file's authenticity and integrity.
