Readers learn by writing and analyzing real programs in Python and Java, exploring both classical cryptographic ideas and the modern algorithms that protect today's digital systems.\u003c\/p\u003e\u003cp\u003eThe book begins with historical and classical ciphers that introduce the fundamental ideas behind encryption and code breaking. It then develops the mathematical foundations needed for modern cryptography, including modular arithmetic and number-theoretic algorithms. Building on this foundation, readers explore symmetric cryptography, hash functions, public-key systems such as RSA, and the practical use of digital signatures.\u003c\/p\u003e\u003cp\u003eThe final chapters introduce post-quantum cryptography, including lattice-based schemes such as ML-KEM (Kyber) and ML-DSA (Dilithium), which are part of the emerging standards designed to remain secure in the presence of quantum computers.\u003c\/p\u003e\u003cp\u003eThroughout the book, numerous programming examples and exercises allow readers to experiment with cryptographic algorithms, measure their performance, and observe both their strengths and potential pitfalls.\u003c\/p\u003e\u003cp\u003eTopics covered include: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eClassical ciphers and cryptanalysis\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eModular arithmetic and number theory for cryptography\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSymmetric encryption and modes of operation\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eHash functions and message authentication\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eRSA encryption and digital signatures\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eImplementation pitfalls and security considerations\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003ePost-quantum cryptography and modern standards\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAll source code used in the book is freely available in the accompanying GitHub repository, making it easy for readers to reproduce experiments and extend the examples.\u003c\/p\u003e\u003cp\u003eThis book is suitable for undergraduate and graduate courses in cryptography, as well as for programmers and security professionals who want a practical introduction to the algorithms that secure modern communication.\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":47775802556567,"sku":"9798252265308","price":1505.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9798252265308.webp?v=1777992538","url":"https:\/\/atlanticbooks.com\/products\/practical-cryptography-from-classical-ciphers-to-post-quantum-standards-9798252265308","provider":"Atlantic Books","version":"1.0","type":"link"}
