Preparing for the Post-Quantum Era
Quantum computers will break today's RSA and ECC encryption. QCecuring helps you inventory cryptographic assets, plan your migration, and transition to NIST post-quantum standards before Q-Day arrives.
Why Current Cryptography Is at Risk
Shor's Algorithm
Shor's algorithm enables a sufficiently powerful quantum computer to factor large integers and compute discrete logarithms in polynomial time. This breaks RSA-2048 and ECC-256, the two most widely deployed public-key cryptosystems.
Harvest-Now-Decrypt-Later
Nation-state adversaries and advanced threat actors are capturing encrypted network traffic today. They store this data until quantum computers can decrypt it, exposing secrets with long confidentiality requirements.
Q-Day Timeline
Researchers and government agencies estimate that cryptographically relevant quantum computers could arrive between 2030 and 2040. Organizations protecting data with multi-decade lifespans must begin migration now.
The New Cryptographic Standards
ML-KEM (FIPS 203)
Module-Lattice-Based Key-Encapsulation Mechanism. Replaces ECDH and RSA key transport for establishing shared secrets. Based on the CRYSTALS-Kyber algorithm, ML-KEM provides fast key exchange with compact ciphertext sizes.
ML-DSA (FIPS 204)
Module-Lattice-Based Digital Signature Algorithm. Replaces RSA and ECDSA for digital signatures. Based on the CRYSTALS-Dilithium algorithm, ML-DSA delivers efficient signing and verification for certificates and code signing.
SLH-DSA (FIPS 205)
Stateless Hash-Based Digital Signature Algorithm. Provides algorithm diversity as a hash-based alternative to lattice signatures. Based on SPHINCS+, SLH-DSA relies only on hash function security for long-term resilience.
How QCecuring Enables Post-Quantum Migration
Certificate Lifecycle Management
Discover every certificate across your infrastructure, enforce crypto-agility policies, and automate renewal with post-quantum algorithms as CAs begin issuing PQC certificates.
Learn moreSSH Key Lifecycle Management
Rotate SSH keys across your environment to transition from RSA and ECDSA to quantum-resistant algorithms. Enforce key governance policies during the migration window.
Learn moreCode Signing
Protect your software supply chain during the PQC transition. Ensure code integrity with quantum-resistant signatures and maintain trust in signed artifacts throughout migration.

Read topicPost-Quantum Cryptography FAQ
What is post-quantum cryptography? +
Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to resist attacks from quantum computers. NIST finalized three PQC standards in 2024: ML-KEM (FIPS 203), ML-DSA (FIPS 204), and SLH-DSA (FIPS 205).
When will quantum computers break current encryption? +
Most researchers estimate cryptographically relevant quantum computers could emerge between 2030 and 2040. The exact timeline is uncertain, but the harvest-now-decrypt-later threat means adversaries are already capturing encrypted data for future decryption.
What is the harvest-now-decrypt-later threat? +
Harvest-now-decrypt-later (HNDL) is a threat model where adversaries capture encrypted data today and store it until quantum computers can decrypt it. This makes PQC migration urgent for organizations protecting long-lived secrets.
How does QCecuring help with PQC readiness? +
QCecuring's CLM platform provides certificate inventory and automated renewal that supports crypto-agility. SSH KLM manages key rotation for algorithm transitions. Code Signing secures software supply chains during migration. The upcoming CBOM capability will inventory all cryptographic assets.
What is crypto-agility? +
Crypto-agility is the ability to rapidly switch cryptographic algorithms, key sizes, and protocols without major infrastructure changes. It is essential for PQC migration because organizations need to transition from RSA/ECC to ML-KEM/ML-DSA across their entire infrastructure.
What is a Cryptographic Bill of Materials (CBOM)? +
A CBOM is a CycloneDX-based inventory of all cryptographic assets in a system — algorithms, keys, certificates, and protocols. CBOM is QCecuring's next planned offering and is essential for understanding your cryptographic exposure before PQC migration.
