Quantum computers pose an existential threat to RSA encryption, the security backbone of the internet. But when will this happen, and why should you care now?

Current State of Quantum Computing

As of 2025, quantum computers with 100-1000 qubits exist, but breaking 2048-bit RSA requires millions of stable qubits. Experts predict this capability will arrive between 2030-2040.

The 'Harvest Now, Decrypt Later' Problem

Adversaries are already collecting encrypted data today, storing it until quantum computers become powerful enough to decrypt it. Your encrypted communications from 2025 could be read in 2035.

Why RSA Is Vulnerable

RSA relies on the mathematical difficulty of factoring large numbers. Shor's algorithm, running on a quantum computer, can factor these numbers exponentially faster than classical computers.

What You Can Do Now

Transition to post-quantum cryptography today. CQRIT uses PQXDH protocol, immune to both classical and quantum attacks. Don't wait until it's too late.

Harvest Now, Decrypt Later (HNDL) is a strategic attack where adversaries collect encrypted data today, betting on future technological advances to decrypt it.

Who's At Risk?

Anyone transmitting sensitive data that will remain valuable for 10+ years: medical records, financial information, government secrets, intellectual property, and personal communications.

The Economics of HNDL

Storage is cheap. Collecting terabytes of encrypted traffic costs virtually nothing compared to the potential value of future decryption. It's a low-risk, high-reward strategy for nation-states and sophisticated actors.

Defense Strategies

1. Use post-quantum encryption now
2. Minimize data transmission
3. Use offline encryption when possible
4. Implement forward secrecy
5. Regularly rotate keys with quantum-safe algorithms

CQRIT's Solution

CQRIT's offline, quantum-safe encryption means your data is never transmitted in a form vulnerable to HNDL attacks. Keys generated from memory leave no trace to harvest.

Most encryption today relies on cloud services, creating inherent vulnerabilities: server breaches, surveillance, compliance with government requests, and single points of failure.

Benefits of Offline Encryption

1. Zero Trust Architecture: No need to trust any third party when everything happens locally.

2. Surveillance Resistance: No data transmission means no interception opportunities.

3. Compliance Simplification: Data that never leaves your device doesn't face cross-border regulations.

4. Universal Accessibility: Works anywhere, even in remote locations or air-gapped environments.

Real-World Applications

Journalists in hostile territories, activists under surveillance, businesses with sensitive IP, and individuals who value privacy all benefit from offline encryption.

The Technical Reality

Modern devices are powerful enough to perform cryptographic operations locally. WebAssembly and native applications like CQRIT make offline encryption practical and user-friendly.
