Online Cryptography Courses

Cryptography courses explore the theory and techniques of deciphering codes and protecting sensitive information, along with how cryptography relates to mathematics and cybersecurity. Learn about subject areas, example courses and online programs. Schools offering Applied Communications degrees can also be found in these popular choices.

What Topics Do Online Cryptography Courses Cover?

Cryptography courses are available online as part of study in cybersecurity, computer science or mathematics. These classes cover methods for creating and breaking codes, the mathematical models behind the codes, encrypting passwords and authenticating digital signatures. Some examples of courses include:

Mathematics and cryptography

Many courses will cover the foundations of cryptography in math models and theories. These can include a look at the theory of numbers as well as information about probability. The mathematical functions used in making and breaking codes will also be studied.

Cryptography in cybersecurity

Well-written cryptography in computer encryption can be the difference between a vulnerable and a well-constructed computer network infrastructure. This course is usually one of the essentials in online cybersecurity degree programs, proving cryptography is one of the core disciplines of computer security study.

Defending computer systems

A course like this will allow students to learn the tools with which to combat an attack on an information system. How cryptography knowledge is vital to the creation of vulnerabilities, as well as the tools needed to fix systems and defend them from hackers, will also be explored.

Types of encryption

In these courses, students learn about the connection between cryptography and online encryption techniques, which allow sensitive data and financial transactions to be shared online. The lessons can include information on public keys and symmetric encryption.

Cryptocurrencies

The rise of Bitcoin and other cryptocurrencies has opened up this new field of study. These courses explain the connection between blockchain currencies, cryptography and how programmers can build tools to interact with them.

At Which Levels Are Courses Available?

Online cryptography courses can be found as standalone classes offered by universities to the public, but also may be a part of degree and certificate programs at for-profit and non-profit colleges. Some classes award grades and credits toward a degree or certificate, while others are just offered for educational opportunities. Most commonly, cryptography course information is offered as part of programs in information security or cybersecurity. Graduate programs usually take 2-3 years to complete, while online certificates can take just over six months.

How Do I Complete Online Courses?

Online courses are flexible, allowing students to view multimedia presentations, read a professor's lecture notes or download lessons at any time. You'll need a computer with high-speed Internet access in order to participate.
