## Why do we need to study cryptography?

That is, we can use cryptography methods to keep information private (say documents, passwords, etc on your computer), and to communicate in a way such that only the intended recipient can read the message.

…

Performing encryption and decryption requires secret information such as passwords (or keys)..

## Is cryptography a good career?

Professional cryptographers need to possess at least a bachelor’s degree in computer science, mathematics or a related field. … If you enjoy constant learning and the everyday task of deciphering coded data and create encryption systems, you’ll find that cryptography is a satisfying profession.

## Why do companies use cryptography?

Encrypted data represents an insurmountable challenge from which they cannot profit. Such use of encryption to protect your data and keep it from being used by perpetrators is a prime example of using cryptography for business. As you look across your enterprise, ask about the data you and your customers depend upon.

## Are cryptographers in demand?

The demand across all industries for increased computer security is growing, and cryptography is a subcategory within the career field of information security.

## Is cryptography hard to learn?

Cryptography is harder than it looks, primarily because it looks like math. Both algorithms and protocols can be precisely defined and analyzed. This isn’t easy, and there’s a lot of insecure crypto out there, but we cryptographers have gotten pretty good at getting this part right.

## What do you learn in 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.
