Poznaj historię rozwoju kryptografii Opanuj jej matematyczne podstawy Rozpracuj najważniejsze algorytmy kryptograficzne Dowiedz się, jak zastosować je w praktyce Kryptografia to dziedzina nauki, której sedno stanowią sposoby bezpiecznego przekazywania informacji. Jest ona niemal tak stara, jak nasza cywilizacja, a dziś rozwija się w sposób niezwykle dynamiczny. Gdy tylko narodziły się pierwsze metody zapisu i komunikowania się, pojawiła się też konieczność zabezpieczenia informacji przed tymi, którzy mogliby wykorzystać je na niekorzyść osób dysponujących tymi informacjami. Od bezpieczeństwa ważnych informacji zależały często losy całych państw i narodów. O rozstrzygnięciach wielkich bitew nierzadko decydowały inteligencja i determinacja pojedynczych osób, które potrafiły odpowiednio skutecznie szyfrować (bądź też deszyfrować) nadawane (lub przechwytywane) komunikaty. O tej fascynującej dziedzinie wiedzy opowiada książka Podstawy kryptografii. Wydanie III. Wprowadza ona czytelnika w podstawowe zagadnienia kryptografii bez przygniatania nadmiarem teorii i skomplikowaną matematyką. Kusi za to barwnymi opisami i pasjonującymi przykładami "kryptograficznych wojen". Można dzięki niej poznać historię rozwoju technik szyfrowania informacji, matematyczne podstawy kryptografii, stojącą za nią teorię oraz praktyczne zastosowania tej nauki. Niezależnie od tego, czy chcesz poznać kryptografię na własny użytek, czy jest Ci to potrzebne w celach zawodowych, książka ta okaże się doskonałym przewodnikiem po świecie szyfrów, kluczy i algorytmów zabezpieczających dane. Znajdziesz w niej informacje na temat protokołów SSL i SSH, a także szczegółowy opis algorytmu SHA3. Przegląd klasycznych sposobów szyfrowania Matematyczne podstawy kryptografii Praktyczne zastosowanie mechanizmów matematycznych Teoria kryptoanalizy i informacji oraz jej praktyczne wykorzystanie Przegląd protokołów kryptograficznych Klucze publiczne i prywatne Zasady zabezpieczania danych, połączeń i systemów komputerowych Potwierdzanie tożsamości za pomocą podpisów elektronicznych Zabezpieczanie stron internetowych i szyfrowanie baz danych Naucz się chronić cenne dane!

Rust for Blockchain Application Development. Learn to build decentralized applications on popular blockchain technologies using Rust

Akhil Sharma

Before Rust, blockchain developers didn’t have a systems programming language that was type-safe, fast, and, at the same time, had stable and easy memory management. Rust proved to be a boon for developers and works as the perfect solution for not only blockchain and protocol development but also dApp development.Rust for Blockchain Application Development focuses on demonstrating solutions that can help blockchain developers productize decentralized applications using Rust, which is a complex language with a steep learning curve.This book starts with basic Rust language concepts and then builds on these concepts to enable you to develop your own blockchain from scratch. As you progress, you’ll learn how to build dApps on popular chains like Solana and NEAR. You’ll also be guided through creating Ethereum dApps using Foundry (Rust). Finally, you’ll develop a custom blockchain using Substrate by Parity (Polkadot). The book provides a complete 360-degree view of Rust in the blockchain ecosystem.By the end of this Rust book, you’ll have a thorough understanding of how to apply your Rust knowledge to building dApps and blockchains from scratch.
