Job Description for a Cryptographer

Cryptographers focus on creating encryption algorithms. The job includes several different skill sets, including computer science, mathematics, and linguistics.

As computer networks become more complex, cryptographers will likely play an increasingly critical role in keeping online information secure. To do so, cryptographers often work with peers to build new cryptographic schemes or algorithms for their research projects.

Cryptographers may face professional challenges. For instance, their work may take years to yield any progress. They also need to stay up to date on new advances in technology and cryptography trends. The role demands creative thinking and advanced understanding of mathematical concepts such as number theory, finite fields, and calculus.

For many cryptographers, day-to-day responsibilities involve developing stronger codes to protect sensitive data or finding flaws in existing encryption protocols. Some work with computer scientists and other professionals to evaluate operating system security. Others specialize in breaking current codes so that companies can know what not to do next time.

Consider the key duties in a crypgorapher's job description listed below:

Main Duties of Cryptographers

  • Audit Cryptographic Code: As part of an audit, cryptographers use crypto primitives to find coding flaws that a hacker could exploit. Audits can also include looking for weak hashes, block ciphers, and legacy ciphers.
  • Test Cryptology Theories: Cryptography practice rests on number theory. Data encryption relies on specific ciphers, usually public key ciphers, that demand advanced mathematical theory. Cryptographers determine how hackers could decode a particular cipher depending on the number theory it relies on.
  • Use Different Cryptography Types to Enhance Encryption: Modern cryptographers code and decode information using several techniques, algorithms, and methods. These fall under one of two cryptography types — symmetric or asymmetric. Symmetric encryption works within closed systems. Asymmetric encryption, sometimes called public key encryption, is available in open or public systems.
  • Work With Encryption Algorithms: Modern cryptographers typically use one of five common encryption algorithms. These are advanced encryption standard (AES), triple data encryption standard, Rivest-Shamir-Adleman, Blowfish, and Twofish. AES is the most common and the most effective against attackers. Cryptographers need to know how to use each of these algorithms.
  • Prototype Cryptographic Primitives: Cryptographic primitives are low-level algorithms that cryptographers use to build cryptographic models. These primitives include one-way hash function, symmetric key cryptography, and digital signatures. Other examples include public-key cryptography, commitment scheme, and pseudo-random number generators. Cryptographers also create new algorithms to encrypt data.

Nonstandard Duties for Cryptographers

  • Write Training Materials: Cryptography's complexity can make the subject difficult for even seasoned cybersecurity experts to understand. Cryptographers may need to train their colleagues on their processes and outcomes. A cryptographer may develop training materials for software engineers and other cybersecurity team members.
  • Consult for Security Organizations: Cryptographers with broad-based cybersecurity knowledge may consult for national security agencies, corporations, and security specialists. In this role, they help create and maintain security systems, train other cryptographers, and develop security algorithms. They may also help develop security policies and identify risks.
  • Document Research Findings: In a university, laboratory, or technology engineering setting, some cryptographers conduct research into the math and science that make up their discipline. These researchers need to document their findings before peer review and publication.
  • Prototype New Security Solutions: Hackers begin their work as soon as a new solution is put in place. What is unhackable today could be cracked tomorrow, so cryptographers must begin developing new solutions right away. These solutions might include tools for end-to-end post-quantum cryptography built to withstand both traditional and quantum computing security risks.
  • Keep Up With Current Research: Cryptography's boundaries are constantly expanding. A keen cryptographer needs to stay on top of the latest information, tools, algorithms, and technologies. To do this, they might earn a master's degree or a doctorate, read the Journal of Cryptography, attend professional conferences, or register for an industry certification.

The Day to Day for a Cryptographer

A cryptographer's end goal depends on where they work. For instance, federal cybersecurity employees may work to identify criminals or strengthen national security. Corporate cryptographers may focus on protecting cash transfers.

A typical day for a cryptographer involves developing algorithms, creating security systems, and devising ciphers that encrypt sensitive information. Their day might also include handling data breach reports and security incidents. From there, they could move into discussions with a client about best-use practices or cryptography strategy updates.

A cryptographer's tasks can also vary by workplace. For example, one business might want their cryptographer to figure out how to strengthen their data protection. Another may need help deciding if they need cryptologic services at all.

At any point, a cryptographer might handle operational activities like reviewing system logs for anomalies or automating routine tasks. Consider the following schedule:

  • Morning: Work on a Java coding project with a multilingual team.
  • Afternoon: Collaborate with a Ph.D. student on a new computational research model.
  • Evening: Make a presentation about a new security tool to the management team.

Where Cryptographers Work

Cryptographers can work across many industries and locations. These professionals often hold jobs with the federal government, technology firms, and research institutions. Many cryptographers work in traditional office settings located in urban centers. Others work remotely.

Cryptography jobs cluster around major technology, finance, or national security hubs such as California, New York, Virginia, and Maryland. Employers in these states may also offer some of the highest wages. Cryptographers in these areas may work for the federal government or one of its contractors or for technology firms.

For example, both the National Security Agency and the Department of Defense hire cryptographers. In the private sector, engineering firms, blockchain companies, neurotechnology organizations, and social networking companies all employ cryptographers. Many jobs in Virginia and Maryland center on U.S. government work. Jobs in California and New York may focus more on private enterprise.

Blockchain presents an area of particular interest for cryptographers. While many people know the blockchain because of cryptocurrency, the chain is actually more widespread. Blockchain is now a leading technology in automated payments, insurance, transportation, and logistics. Cryptographers secure the transactions between the chain's nodes.

Cryptographers with advanced degrees in electrical engineering or computer science may teach at a university or work for a research firm. These professionals can serve in locations throughout the U.S. and abroad.
