About the Cryptography test

Cryptography is one of the most important fields in computer science today. Virtually all businesses store data of some form or another in databases; securing that data and preventing it from getting into the wrong hands is a growing challenge. For this reason, hiring candidates with a strong knowledge of cryptography is essential to keeping your business and customer data safe from potential threats.

This Cryptography test evaluates candidates’ knowledge of public and private key cryptography, as well as their skills and abilities in using digital signatures, hashing, and message authentication codes.

This screening test will help you identify cryptographers who know how to ensure that data is exchanged securely between parties, how to store data securely in a database, and how to ensure authentication and verification of important documents.

This cryptography test makes use of scenario-based questions, ensuring that candidates who do well on this screening test have the skills to make decisions based on key cryptographic and data-security concepts. This test will help you hire cryptographers who are skilled in keeping your business data secure.

The test is made by a subject-matter expert

Usman A.

Usman has a degree in computer science from FAST, the Foundation for Advancement of Science and Technology in Islamabad, Pakistan. He enjoys exploring new tools, techniques and practices in the fields of cryptography and cyber security, and has a keen interest in cracking codes, solving ciphers, and implementing ciphers into code. Usman incorporates cryptographic concepts like password hashing and database privacy when he designs and implements websites in React Javascript.

Review from G2

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.
