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.

Download or read book ELLIPTIC CURVE CRYPTOGRAPHY (ECC) KEY GENERATION, ENCRYPTION, DECRYPTION, AND DIGITAL SIGNATURES: LEARN BY EXAMPLES WITH PYTHON AND TKINTER written by Vivian Siahaan and published by BALIGE PUBLISHING. This book was released on 2024-08-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the development of a sophisticated and feature-rich Tkinter GUI that leverages Elliptic Curve Cryptography (ECC) for various cryptographic operations, including key generation, encryption, decryption, signing, and verifying data. The primary goal is to create an interactive application that allows users to perform these operations on synthetic financial data, demonstrating the practical use of ECC in securing sensitive information. The GUI is meticulously designed with multiple tabs, each corresponding to a different cryptographic function, enabling users to navigate through key generation, data encryption/decryption, and digital signature processes seamlessly. The GUI starts with the key generation tab, where users can generate ECC key pairs. These key pairs are essential for the subsequent encryption and signing operations. The GUI provides feedback on the generated keys, displaying the public and private keys in hexadecimal format. This feature is crucial for understanding the foundational role of ECC in modern cryptography, where small key sizes provide strong security. The key generation process also highlights the advantages of ECC over traditional RSA, particularly in terms of efficiency and security per bit length. In the encryption and decryption tab, the GUI enables users to encrypt synthetic financial data using the previously generated ECC keys. The encryption process is performed using AES in Cipher Feedback (CFB) mode, with the AES key derived from the ECC private key through key derivation functions. This setup showcases the hybrid approach where ECC is used for key exchange or key derivation, and AES is employed for the actual encryption of data. The GUI displays the generated ciphertext in a hexadecimal format, along with the Initialization Vector (IV) used in the encryption process, providing a clear view of how the encrypted data is structured. The signing and verifying tab demonstrates the use of ECC for digital signatures. Here, users can sign the synthetic financial data using the ECDSA (Elliptic Curve Digital Signature Algorithm), a widely recognized algorithm for ensuring data integrity and authenticity. The GUI displays the generated digital signature in hexadecimal format, offering insights into how ECC is applied in real-world scenarios like secure messaging and digital certificates. The verification process, where the signature is checked against the original data using the ECC public key, is also integrated into the GUI, emphasizing the importance of digital signatures in verifying data authenticity. The synthetic financial data used in these operations is generated within the GUI, simulating transaction records that include fields such as transaction ID, account number, amount, currency, timestamp, and transaction type. This dataset is crucial for demonstrating the encryption and signing processes in a context that mirrors real-world financial systems. By encrypting and signing this data, users can understand how ECC can be applied to protect sensitive information in financial transactions, ensuring both confidentiality and integrity. Finally, the GUI’s design incorporates user-friendly elements such as scrolled text widgets for displaying long hexadecimal outputs, entry fields for user inputs, and clear labels for guiding the user through each cryptographic operation. The application provides a comprehensive and interactive learning experience, allowing users to explore the intricacies of ECC in a controlled environment. By integrating ECC with AES for encryption and ECDSA for signing, the GUI offers a practical demonstration of how modern cryptographic techniques can be combined to secure data, making it an invaluable tool for anyone looking to understand or teach the principles of ECC-based cryptography.

Download or read book Decrypting the Encryption Debate written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-06-07 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encryption protects information stored on smartphones, laptops, and other devices - in some cases by default. Encrypted communications are provided by widely used computing devices and services - such as smartphones, laptops, and messaging applications - that are used by hundreds of millions of users. Individuals, organizations, and governments rely on encryption to counter threats from a wide range of actors, including unsophisticated and sophisticated criminals, foreign intelligence agencies, and repressive governments. Encryption on its own does not solve the challenge of providing effective security for data and systems, but it is an important tool. At the same time, encryption is relied on by criminals to avoid investigation and prosecution, including criminals who may unknowingly benefit from default settings as well as those who deliberately use encryption. Thus, encryption complicates law enforcement and intelligence investigations. When communications are encrypted "end-to-end," intercepted messages cannot be understood. When a smartphone is locked and encrypted, the contents cannot be read if the phone is seized by investigators. Decrypting the Encryption Debate reviews how encryption is used, including its applications to cybersecurity; its role in protecting privacy and civil liberties; the needs of law enforcement and the intelligence community for information; technical and policy options for accessing plaintext; and the international landscape. This book describes the context in which decisions about providing authorized government agencies access to the plaintext version of encrypted information would be made and identifies and characterizes possible mechanisms and alternative means of obtaining information.
