FAQs

What Is a Cryptanalyst?

First, let’s review what this job entails. As Coursera explains, a cryptanalyst is a “professional codebreaker,” with the job title coming from the Greek words kryptós (“hidden”) and analýein (“to analyze”). In this role, a person is responsible for

“analyzing hidden messages by decoding or decrypting data, even without the encryption key.”

Common Cryptanalysis Terms

If you’re interested in cryptanalysis positions, you should familiarize yourself with three important terms:

  • Plaintext — This is defined as any type of plain, readable text (messages, documents, emails, files, etc.).
  • Ciphertext — This term refers to plaintext that has been transformed, either through encryption, algorithms or ciphers.
  • HashingThis refers to the process of translating a key into a different value or code.

We also recommend checking out the comprehensive Cybersecurity Glossary from the National Initiative for Cybersecurity Careers and Studies and the Glossary of Security Terms from the SANS Institute.

Cryptanalyst vs. Cryptographer vs. Cryptologist

You may have heard of cryptography or cryptology, but they are not the same as cryptanalysis. Let’s explain it all, including the difference between cryptography and cryptanalysis:

  • Cryptanalysis – “The decryption and analysis of codes, ciphers or encrypted text. Cryptanalysis uses mathematical formulas to search for algorithm vulnerabilities and break into cryptography or information security systems.”
  • Cryptography – “The study of conversion of plaintext (readable format) to ciphertext (non-readable format) i.e. encryption. It is also called the study of encryption.”
  • Cryptology – “The study of the conversion of plaintext to ciphertext and vice versa. It is also called the study of encryption and decryption.”

To put it simply, cryptanalysis is the study of breaking codes, cryptography is the study of creating codes and cryptology is the study of both.

What Does a Cryptanalyst Do?

A cryptanalyst is a mathematically focused position centered around protecting data from those who will use it nefariously. “A cryptanalyst develops mathematical methods and codes that protect data from computer hackers,” explains CareerExplorer. “This involves the decryption of a ciphertext into plaintext in order to transmit a message over insecure channels.”

Cryptanalyst Job Description

The specifics of the job will vary depending on the position, but here are some common cryptanalyst job responsibilities, courtesy of Comparitech:

  • Protect important information from interception, modification, duplication or deletion
  • Evaluate, analyze and target weaknesses in cryptographic security systems and algorithms
  • Design strong security systems that prevent vulnerabilities
  • Develop statistical and mathematical models that allow you to analyze data and solve security issues
  • Test computational models for both accuracy and reliability
  • Investigate, research and test new cryptanalysis theories and applications
  • Stay up to date on the latest technologies that hackers are using
  • Identify, configure, implement and test the latest tools in cryptanalysis
  • Develop codes or new coding methods
  • Monitor and detect issues in data flow or collection
  • Debug and test software programs
  • Analyze and decode encrypted messages

Career Paths to Become a Cryptanalyst

In order to become a cryptanalyst, you must first obtain the right education and explore relevant certifications. It’s also important to continue to enhance your knowledge and skills (and stay up to date on the latest trends) even after you secure a position, especially since the cybersecurity world is constantly changing.

Cryptanalyst Education Requirements

In most cases, you need a minimum of a bachelor’s degree in a relevant field, such as cybersecurity, computer programming, computer science, computer engineering, software development or IT. Some employers, however, may require a master’s degree in a related subject. As CareerExplorer points out, many cryptanalysts have advanced degrees (either master’s or doctoral); this is especially important for anyone who would like to teach at the college or university level.

Career Outlook for a Cryptanalyst

In general, the outlook for all types of cybersecurity positions is extremely favorable. As Cybersecurity Guide explains:

“The worldwide staffing shortage in the cybersecurity industry is well documented, and cryptanalysis is no different. There is a certain spy world attraction to being a cryptanalyst that constantly brings new mathematicians and computer scientists into the field. But the constant evolution and advancement in computer sciences, the rapid expansion of digital techniques used in law enforcement and espionage is creating new demand for cryptanalysts. And this is likely to continue for the foreseeable future.”
