Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. We will examine many deployed protocols and analyze mistakes in existing systems.

## How can I study cryptography?

The path to a career in cryptography begins with a bachelor’s degree in computer science, computer engineering, or related field. Coursework develops foundational knowledge and skills in mathematics, computer and information technology systems, and programming languages.

**Is it hard to learn cryptography?**

Cryptography is a field that combines three different subjects; mathematics, computer science, and information security. As such, it can be very hard to learn, especially if you have little or no knowledge of the aforementioned subjects.

**What is cryptography easy?**

Cryptography, or cryptology, is the practice and study of hiding information. When a message is sent using cryptography, it is changed (or encrypted) before it is sent. The method of changing text is called a “code” or, more precisely, a “cipher”. The changed text is called “ciphertext”.

### Does cryptography need math?

Analytical Skills Cryptography professionals need to have a strong understanding of mathematical principles, such as linear algebra, number theory, and combinatorics. Professionals apply these principles when they are designing and deciphering strong encryption systems.

### What is a cryptographer salary?

As of 2021, the average annual cryptographer salary is over $145,356. The top earners in this field make as much as $195,000 or more and the bottom 4% make around $102,000 per year. A career as a cryptographer can be financially rewarding.

**What are types of cryptography?**

Cryptography can be broken down into three different types:

- Secret Key Cryptography.
- Public Key Cryptography.
- Hash Functions.

**Where is RSA used today?**

RSA is still seen in a range of web browsers, email, VPNs, chat and other communication channels. RSA is also often used to make secure connections between VPN clients and VPN servers. Under protocols like OpenVPN, TLS handshakes can use the RSA algorithm to exchange keys and establish a secure channel.
