Are you ready to find a school that's aligned with your interests?

If you like solving puzzles, cryptography may be the career for you.

Many organizations deal with sensitive information. A certified cryptographer helps safeguard information by writing and solving encryption codes.

Cryptographers develop and use cryptographic software and methods. Their main goal is to ensure data privacy, authentication, and non-repudiation. According to Glassdoor , cryptography professionals earned an average annual salary of $98,190 as of December 2021. Certification may help boost this salary.

Certification shows that a professional has mastered a specific set of skills and knowledge. Candidates usually need to fulfill education and experience prerequisites. Most cryptographer certifications also include a written exam and an ethical standards pledge.

This article provides an overview of cryptography certifications along with advice on how to prepare for the exams and choose the top certifications for cryptographers.

What Is Certification in Cryptography?

Are cryptographers licensed or certified?

States issue licenses to perform jobs like cosmetology, medicine, and accounting. Most states, however, do not regulate cryptographers or cryptographic products. Therefore, cryptographers do not hold licensure.

By contrast, professional organizations issue certifications. Employers may expect cryptographers to hold certifications, but the state does not. Some cryptographers are certified while others are not. Certifications can help affirm a cryptographer's knowledge of critical areas like cryptographic attacks, public-key cryptography, and symmetric-key algorithms.

Aspiring cryptographers should thoroughly research available certifications. The best certifications for cryptographers offer a positive return on investment.

Why Pursue Certification?

Certifications offer a good way to advance a career as a cryptographer . They can lead to improved job prospects, increased opportunities, and expanded knowledge.

By completing one of the best certifications for cryptographers, cybersecurity professionals can prove their cryptography expertise. Certification also helps professionals stay current with the industry's technology and methods . In cryptography, keeping up to date is crucial because both jobs and threats can change quickly.

Some organizations require cryptographers to hold specific certifications. For example, the U.S. Department of Defense (DOD) Directive 8140 requires select cybersecurity professionals to earn a certification. Professionals seeking a DOD job should confirm that their chosen certification meets this rule.
