“Safeguarding Digital Assets in the Quantum Era” with Qrypt, Interview and Discussion
featuring CTO and Co-Founder, Denis Mandich

In a digital landscape where the security of our data remains vital, the emergence of quantum
computing poses an unprecedented challenge. I had the pleasure of interviewing Denis
Mandich, CTO, and co-founder of Qrypt, a cybersecurity company dedicated to fortifying our
digital defenses against the looming quantum threat.

Mandich began our conversation by highlighting a fundamental vulnerability in traditional
encryption methods - the "harvest now, decrypt later" vulnerability. Qrypt has devised a
revolutionary cryptographic solution that eliminates this vulnerability by shunning key
transmission altogether. Instead, it safeguards the process using independently generated keys,
making it the only cryptographic solution capable of securing data indefinitely. This
groundbreaking approach hinges on the generation of one-time pads and symmetric keys at
multiple endpoints, boosting data security to an unprecedented level.

Mandich emphasized that the internet, as it stands today, was not constructed with security in
mind. This glaring oversight has left us lagging behind in the race to secure our digital assets
against quantum threats. He noted that China, for instance, has made significant strides in
quantum technology and cybersecurity, underscoring the urgency for the rest of the world to
catch up.

Qrypt's mission, as outlined on their website, is to address this vulnerability by delivering
quantum-secure encryption solutions that empower individuals and organizations to protect their
data and privacy relentlessly. Both of the founders, Mandich and Kevin Chalker, have curated
an exceptional team of experts in engineering, physics, and cryptography to set a new standard
in security. They've also forged strategic partnerships with quantum hardware companies and
research institutions to create the only cryptographic solution capable of securing data
indefinitely.

At the heart of Qrypt's technology lies true quantum randomness, the bedrock of their innovative
approach. Combined with advanced techniques and algorithms, the Qrypt SDK enables the
development of quantum-secure applications. Qrypt offers several products tailored to meet the
evolving security needs of businesses and developers:

1. Entropy: Providing businesses with high-rate quantum random numbers through an
easy-to-use REST API, ensuring secure encryption.
2. Key Generation: Offering a service that generates identical keys at multiple endpoints,
protecting against the future quantum threat and avoiding key interception. See Fig. 2 for
a closer look at Qrypt’s key generation process.
