It is essential to get the relevant skills when you need a career change or add to your abilities. However, you must know what to expect before investing your time and money into it. Cryptography, for instance, is lucrative but demanding; hence, we aim to provide you with the right information to make it a walkover for you.
So, is cryptography hard to learn? Cryptography is not hard to learn if you have a background in mathematics or computer science, since it relies heavily on the principles from these subject areas. People without a background in mathematics or computer science may struggle with learning cryptography.
Considering it is a technical course, it will be easy if you have a bachelor’s degree or master’s degree in mathematics or computer science. You may also need at least basic knowledge in computer programming, security protocols, compiler systems, and digital system information to help you learn how to encrypt and decrypt algorithms.
If you are uncertain about whether cryptography is the right path for you, this is the guide for you. We will highlight how long it takes to learn cryptography, where to start learning cryptography, and if you can learn cryptography on your own. Read on as we explore these and more concerns.
Cryptography is a unique skill set where you use codes to convey information through various channels safely. The aim is to decrypt the message such that only the recipient accesses and processes it. It’s a high-demand skill in organizations where the only hurdle is that people believe it’s too complex.
Cryptography can be easy or hard, depending on the learner. It requires strong motivation, interest, and ease of learning mathematics and computer science. It can be very effortless for you if you are good at the key subjects required and are determined to get it right. Fast learners can easily grasp and apply the concepts and get them right with practice.
If you fall in that category, you may need a couple of months or up to two years to fully understand the ins and outs of cryptography. On the contrary, it may be quite complicated for you if you don’t have any prior knowledge or high affinity to the main subjects.
Cryptography is exceptionally fun for students who easily understand mathematical theories and relevantly apply them in problem-solving. It is best to take a separate course in all the subjects if you don’t have a background in them, but you will find it simple and exciting to learn if you do.

How Long Does It Take To Learn Cryptography?
One of the factors to consider before acquiring a new skill is the time frame. You first need to consider how much time you need to fully master it to plan how best to go about it. It can be full or part-time depending on various factors, and you can decide which works in your favor.
With several factors in consideration, knowledge in cryptography can take you anything between six months to two years. It will take a short time if you have advanced analytical skills or prior knowledge on the required subjects and the commitment to finish the course. You need mathematical and computer science skills to succeed in the complex world of cryptography.
Those with a degree or certification in any or both subjects always have the upper hand since they are familiar with the basic concepts. Therefore, it is easier to grasp and apply the knowledge they obtain along the way.
Learning cryptography may take you less than two years, depending on your skills and affinity to grasp and apply what you have learned. It is easy to pick it up as a science and art as long as you have the motivation to learn. Some brilliant students may only need a couple of months, with some only requiring less than four months.
It may take a short time for you if you take it up full-time and not part-time. You will get more time for hands-on experience and practice more, enabling you to master the basic and complex concepts in no time.
You can get an entry-level job with a degree in mathematics or IT alongside your skills in cryptanalysis. However, a Ph.D. or a master’s degree is more lucrative and can secure you a better-paying job. A higher education level plus cryptology credentials will be more competitive and go a long way to boost your resume. While the theory part is easier to learn, you need more time and analytic skills to grasp the application part of it.
The good thing about the skill is that there are several resources at your disposal, both soft and hard copy, whichever works best for you. Professional cryptographers have also published their wealth of information for you, and you can find all you need at a low cost or no fee. Therefore, you don’t need to worry about spending a fortune to learn cryptography. You also don’t need to enroll in an expensive degree program or purchase countless books.
Where Do I Start To Learn Cryptography?
There are many expectations as a beginner learning cryptography. It is a vast and demanding course; hence, you need to know where your journey to becoming an expert starts.
First, you can enroll for a free course online then find all the related resources. Many people go for platforms like Coursera, Udemy or any other where you can find professional help.
Alternatively, if you have the time and resources, you can go for physical enrollment in an institution that teaches the basics and advanced levels of cryptography and other related courses in cybersecurity.
