Post-Quantum Cryptography

Post-Quantum Ready?

NIST finalized PQC standards in 2024. Is your domain prepared? Vysiro scans your domain's cryptographic setup and identifies what needs to change before quantum computers break classical encryption.

What We Scan

Three critical dimensions of post-quantum readiness

DKIM Signing Readiness (ML-DSA)

Evaluates your DKIM key sizes and signing algorithms against ML-DSA (formerly Dilithium) requirements. Identifies RSA-1024 keys that are most vulnerable to quantum attack and flags upgrade paths.

TLS Key Exchange (ML-KEM)

Analyzes your TLS configuration for ML-KEM (formerly Kyber) key encapsulation readiness. Checks whether your server supports hybrid key exchange and post-quantum cipher suites.

Certificate Algorithm Analysis

Inspects certificate chains for algorithm agility. Identifies certificates using RSA or ECDSA that will need migration paths, and checks for CA support of PQC issuance.

Why It Matters

The quantum threat timeline is shorter than most organizations assume

2024

NIST Finalized Standards

FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) were officially published, marking the start of the post-quantum migration era.

2025-2027

Early Adoption Window

Organizations begin hybrid deployments. Browsers and TLS libraries add ML-KEM support. DKIM signers begin testing larger key formats.

2028-2030

Migration Deadlines

NIST recommends deprecating RSA-2048 for new applications. Federal agencies required to support PQC. Harvest-now-decrypt-later attacks become increasingly viable.

2030+

Cryptographically Relevant Quantum Computers

Projected timeline for quantum computers capable of breaking RSA-2048 and ECC-256. All classical public-key cryptography at risk.

Harvest Now, Decrypt Later

Adversaries are already collecting encrypted traffic today to decrypt once quantum computers become available. Data with long-term sensitivity - financial records, health data, government communications - is at risk now, not in the future.

Available on Starter+ Plans

PQC readiness assessment is included with all paid Vysiro plans. Free scans include a basic cryptographic overview, while Starter and above receive the full ML-DSA, ML-KEM, and certificate algorithm analysis.

  • DKIM key size and algorithm assessment
