What happens if an Early Access Course is cancelled?

Projects are rarely cancelled, but sometimes it's unavoidable. If an Early Access course is cancelled or excessively delayed, you can exchange your purchase for another course. For further details, please contact us here.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.

Reading recent issues on cryptography helps me to increase the arguments I use to find scenarios and explain to the managers of the companies that hire my services how cryptography helps to answer questions and concerns about how to keep information secure.

This book not only builds a crypto foundation but it teachers about real world instances where crypto has been used on servel levels. Providing practical examples and instances where cryptography has been used to solve and provide encryption algorithm as a security solution. I enjoyed the fact that we stepped through the different types of encryption and the way they can be used in the modern world. This book brings you out of the dark on the art of encryption and shines a brilliant light through the fog and misconception about cryptography.This book is an excellent read and it's one to put in your cyber library.

Although the book is aimed at beginner-level IT professionals, students, and cybersecurity enthusiasts, I found certain parts of it hard going, especially since it has been a few decades since I last studied university-level mathematics. However, any decent book on Crypto Algorithms without covering mathematics will leave its readers short-changed. Hence, the inclusion of this in the book is a positive thing.Sections 1 and 2 will introduce you to some of the historical aspects of cryptography and the classical symmetric and asymmetric encryption protocols and standards. It is an excellent way to lay down the foundations.Section 3 covers the newer algorithms and protocols. I found the Zero-Knowledge Protocols (ZKP) chapter of particular interest and relevance since it concerns authentication and identity. I enjoyed the author's scenario-based explanation of ZKP (labelled as ". . . the digital cave"), which is a great way to explain a complex topic.Chapter 6, which covers Lightweight encryption (amongst other topics), will be particularly appealing to those with a keen interest in IoT security. The inclusion of a Lightweight encryption Algorithms (LEA/LE) was a highlight for me, and I'm sure it will be for you too.In section 4, we transition over the emerging trends and threats of Quantum Cryptography—an essential topic for any cybersecurity professional. Buckle up for the chapter; you are in for a treat (well, if you are a nerd like me! 🤓 ) - I was fully expecting to read about quantum algorithms, but seeing Q-Mechanics included as well was like a kid in a candy shop.With all that said, is the book worth buying? In my opinion, the wealth of knowledge and insights it offers make it a resounding YES!

In this second edition, the book continues to excel in explaining the fundamentals of cryptography and its crucial role in enabling security in modern technologies. It goes a step further by adding insightful chapters on Quantum Cryptography, providing a thorough understanding of this emerging field. These additions make the book even more comprehensive, ensuring it remains an essential resource for anyone interested in the evolving landscape of cryptographic technologies.

As a cybersecurity professional in digital forensics with over 20 years in IT, I found this book strikes a good balance between foundational concepts and more advanced, cutting-edge topics. The sections on classical cryptography, digital signatures, and symmetric/asymmetric encryption are clear and practical, while the exploration of emerging trends like quantum cryptography and zero-knowledge proofs offers insights into the future. The advanced material can be dense, but overall, this is an excellent resource for both beginners and those looking to deepen their cryptography knowledge.
