Created byPackt Publishing
Last updated 5/2020
English

What you'll learn

  • Develop applications that use an existing reliable cryptography
  • Build complex integrations with other systems, taking advantage of worldwide public key infrastructures and certificates
  • Identify hacking risks in your own and other cryptographic systems and how to fix them
  • Discover cryptographic terms used to describe any system you work on or with
  • Design functioning, well-performing applications that use seamless cryptography

Course content

5 sections • 28 lectures • 2h 49m total length

  • The Course Overview2:23

    This video will introduce you to the course

  • Goals of Cryptography and Where It Is Used5:18

    This video explains the industry background, showing that cryptography appears in almost systems.

       •  Understand what cryptography is used for

       •  Discuss where is cryptography already used

       •  Look at the legal implications of using cryptography

  • History of Cryptography and Why You Shouldn’t Build New Algorithms5:29

    This video shows some evolution of cryptography and how it’s changed. It also shows the standards bodies who decide on algorithms.

       •  Show that cryptography is not new

       •  Identify standards in cryptography

       •  Discuss the importance of audit and appearances

  • The Architectural Layout of Modern Cryptography5:16

    This video helps us to relate cryptography to the broader industry, demonstrating some of the problems solved. It focuses on inter-system communication and public key infrastructure.

       •  Discuss system communication

       •  Identify role of prior knowledge

       •  Show how browsers chain trust

  • Concepts That Will Be Important Later7:27

    The aim of this video is to explain background of concepts like CAs, algorithms, to explain the rest of the upcoming course.

       •  Walk through the public key crypto system (PKCS)

       •  Compare strength between algorithms

       •  Learn the pronunciation of ciphers

Requirements

  • The course requires knowledge of Java programming but does not require a degree in mathematics or advanced computer science.

Description

Security is paramount for any application. Cryptography occurs all across software fields: it protects all HTTPS traffic between browsers, encrypts phone storage against prying eyes, and can even hide files inside other files through a technique called steganography. This course is for developers looking to design a system that uses cryptography, rather than designing new algorithms. Most developers simply need to put the right pieces together to make their own system work.

In this course, you will break down the concepts behind cryptography into simple lessons, covering terminology, algorithms, standards, and encryption/decryption techniques. We will also walk through how cryptographic systems are hacked to bypass (rather than break) their cryptographic capabilities. 

The course answers questions such as:

  • What is cryptography used for?

  • What are keys and where do they go?

  • Why do networked systems sometimes give certificate validation errors?

  • If I need to encrypt something, how should I do that?

By the end of this course, you will recognize cryptographic problems and understand the right knowledge to apply a verifiable solution.

About the Author

Erik Costlow ran Oracle’s Java Root Certificate program, coordinating efforts with many cryptographic organizations. He is an experienced software security expert focused on program analysis and runtime instrumentation to detect security issues and provide useful guidance on fixing any security issues.

Who this course is for:

  • This video course is for developers whose applications require encryption, or integration with an external cryptographic system.
  • Java developers building standard applications that require encryption, developers looking to understand flaws in cryptographic systems, and developers who do not want flaws in their cryptographic systems will benefit from this course.
