Over 10,600 confirmed breaches were reported globally in 2024, exposing millions of records, including sensitive healthcare and financial data. Organizations need cybersecurity professionals who can protect them against this costly risk. This Encryption and Cryptography Essentials course gives aspiring cybersecurity professionals job-ready skills in encryption, hashing, and digital signatures—key competencies employers are looking for.
You’ll master symmetric (AES) and asymmetric (RSA) encryption techniques and apply hashing methods like MD5 and SHA to ensure data integrity. You’ll learn how to manage and verify certificates using the Online Certificate Status Protocol (OCSP). Plus, you’ll explore blockchain technology and its applications. This course is a comprehensive guide to mastering encryption and cryptography in cybersecurity. Through hands-on labs, interactive quizzes, and projects, you’ll learn how to secure digital information, tackle cybersecurity challenges, and implement encryption and cryptographic solutions. If you’re looking to add job-ready encryption and cryptography skills employers need to your resume, enroll today!
In this module, you will learn the foundational concepts of cryptography and its essential role in data security. You will classify cryptographic algorithms by their functions. and conduct cryptanalysis using OpenSSL. The module covers asymmetric and symmetric cryptography principles, including RSA and Elliptic Curve Cryptography (ECC), with practical exercises in RSA and AES encryption. Additionally, you will explore key exchange protocols like Diffie-Hellman and The Elliptic Curve Diffie-Hellman (ECDH), culminating in hands-on experience with Diffie-Hellman key exchanges for secure data transmission

In this course, you'll learn the fundamentals of encryption, including symmetric and asymmetric encryption algorithms, hashing techniques, digital signatures, and the role of Public Key Infrastructure (PKI). You’ll also explore blockchain technology, cryptographic attacks, and methods for securing data in various real-world applications.
As this is an intermediate-level course, basic knowledge of cybersecurity, including cybersecurity architecture, is essential.
You’ll gain hands-on experience with tools like OpenSSL to generate hashes and digital signatures, as well as apply encryption algorithms in practical scenarios. By the end of the course, you’ll be able to implement cryptographic solutions to secure data, protect communication, and evaluate cryptographic methods.
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
