Learn more about what cryptography involves from Dan Boneh, Professor of Computer Science at Stanford University:Įnroll for Free What does a cryptographer do?ĭepending on the organization you work for, your day-to-day tasks as a cryptographer might include: If you have solid data and analytical skills, are interested in both mathematics and codes, and enjoy the challenge of creating effective ciphers, cryptography could be a good fit. They study encryption methods to find new ways to keep data secure while creating keys to the code so that the right users can access the information they need. Modern cryptography is the same what’s different is the nature of the codes and the methods used to encrypt and then decrypt data.Ĭryptographers are critical members of the information security defense team. For millennia, people have used codes to protect their secrets. A cryptographer is responsible for converting plain data into an encrypted format. What is cryptography?Ĭryptography is the practice of writing and solving codes. Fortunately, several degrees and certificate programs can prepare you for this fascinating career. At the same time, those wanting to beat that security are also continually improving their ability to break into computer systems and steal data. You need to understand computer science, mathematics, and programming.ĭata security is complex and constantly changing. Of course, it takes training to learn how cryptography works and how it fits into an information security infrastructure. The US Bureau of Labor Statistics (BLS) expects strong demand and high pay for information security professionals, even with less than five years of experience. To become a cryptographer, you should plan to develop strong computer-based skills, such as the ability to write code and decipher data, through a degree program, internship, or certification program.Ĭryptology is one of many jobs in information security.

Cryptographers use their knowledge of codes and computers to keep data and information safe. Often the job involves cracking-or hacking-codes that encrypt data. Cryptography is the field that looks at how to keep information secure so that only the person who is supposed to see it can. If you like solving puzzles, you might enjoy a career as a cryptographer.
