Right now, hackers are stealing your encrypted data. Not to use today, but to decrypt later with quantum computers they expect to have in 5-10 years.
This isn’t sci-fi; it’s called “Harvest Now, Decrypt Later” (HNDL). And it’s why nearly two-thirds of organizations see quantum computing as their biggest cybersecurity threat in the next 3-5 years, not ransomware, not social engineering, but quantum computing.
OmniPayments’ OmniSecurity platform is already ahead of the curve, racing to implement quantum-safe cryptography while most others are still catching up.
In this guide, we’ll explain why your current encryption is vulnerable, how quantum computers could crack RSA-2048 in minutes.
Your “Secure” Encryption Isn’t Secure Anymore
A quantum computer with just 1 million qubits could break RSA-2048 in minutes using Shor’s Algorithm. Experts believe we’ll have that power within 5-10 years. The uncomfortable truth is, your “secure” data isn’t secure against future threats.
Hackers are currently taking your encrypted data, archiving it, and plotting to decipher it once quantum technology arrives. Your banking transactions, medical records, trade secrets, and government conversations are all being stored for later decryption.
What is Quantum Threat?
What’s vulnerable:
- RSA & ECC: These are widely used for digital signatures and key exchange; however, they are ineffective against a strong quantum computer.
- SHA-256: The backbone of blockchain security is also at risk.
Imagine these scenarios:
- Government/Defense: Classified communications and military strategies could be compromised.
- E-commerce: Your credit card transactions, passwords, and personal data are ripe for HNDL attacks.
The timeline is urgent. While quantum computers capable of breaking current encryption are 5-10 years away, HNDL attacks mean the threat began years ago. Any sensitive data encrypted today is a target.
Three NIST-Approved Algorithms:
- FIPS 203 (ML-KEM): For general-purpose encryption (replacing RSA and ECC). Think website access, data transmission, and key exchange. It offers small, easy-to-exchange keys and fast operation.
- FIPS 204 (ML-DSA): For digital signatures and authentication, ensuring transaction integrity. It uses lattice mathematics, making it immune to Shor’s Algorithm.
- FIPS 205 (SLH-DSA): A backup digital signature standard using a completely different mathematical foundation, providing an extra layer of resilience.
These standards can be implemented now in payment systems, financial platforms, and secure communications. As of October 2025, over half of Cloudflare’s human-initiated traffic already uses post-quantum encryption.
How OmniSecurity is Building the Quantum-Safe Future
OmniSecurity is already implementing quantum-safe cryptography.
Their approach includes:
- Advanced Key Management: OmniCrypto uses Hardware Security Modules (HSM) and quantum-resistant key encapsulation based on NIST standards. It also offers secure key migration and rotation strategies.
- Beyond Standards Encryption: OmniSecurity is designed to support hybrid post‑quantum key exchange and high‑quality hardware randomness for key generation, using multi‑layered encryption that combines classical and post‑quantum‑ready methods. .
- HNDL Protection: They provide retroactive protection for historical data, rekeying mechanisms for existing archives, and data classification to prioritize quantum-safe protection for high-value targets.
- Future-Proof Architecture: OmniPayments’ service-oriented architecture allows for easy integration of new quantum-safe algorithms and seamless security updates without disrupting payment processing.
Quantum-Safe Payment Processing
Payment systems hold the most sensitive financial data. A quantum breach could expose millions of account credentials, transaction histories, and authentication details.
OmniSecurity protects payment ecosystems by:
- Encrypting PIN blocks with quantum-resistant algorithms.
- Encrypting processor links with TLS 1.3 and HSM‑backed keys..
- Protecting transaction logs from future decryption.
- Ensuring PCI DSS compliance with quantum-safe standards.
The result: Payment processors using OmniSecurity can confidently assert their transactions are secure, even against quantum threats.
The Compliance Mandate is Coming
Quantum-safe cryptography is rapidly becoming a regulatory requirement. NIST’s standards indicate that government agencies and financial regulators expect migration to PQC. This shift will accelerate as quantum computing advances and regulatory frameworks solidify.
Organizations adopting quantum-safe cryptography today will avoid the future compliance rush. OmniPayments‘ early adoption positions its clients ahead of these inevitable requirements.
Quantum-Safe is No Longer Optional
Organizations that implement quantum-safe cryptography today gain:
- Immediate protection against HNDL attacks.
- Compliance readiness.
- Customer trust and security leadership.
- Competitive advantage.
