Post-Quantum Migration & Verification

Turn quantum-vulnerable code into verified post-quantum migrations.

QuanteraAI discovers cryptography inside software repositories, understands what it protects, generates supported post-quantum migrations, and verifies that the application still works.

01 — The Problem

Finding vulnerable cryptography is only the beginning.

Organizations can identify RSA or ECC. The expensive part begins when engineers have to determine what the cryptography does, what depends on it, how to replace it, and whether the migration broke anything.

You can't migrate what you can't see.

Public-key cryptography may exist across application code, libraries, certificates, configuration, wrappers, and shared services.

src/vault/
  └─ encryption/
    └─ key-wrap/
      └─ RsaKeyProtectionService.java

The same algorithm can do different jobs.

RSA may protect a symmetric key, generate signatures, or participate in another protocol. Each use requires different migration reasoning.

RSADigital SignatureML-DSA family

A finding is not a fix.

After a scanner reports RSA or ECC, engineers still have to trace dependencies, redesign the cryptographic workflow, write code, test it, rescan it, and document the result.

Quantera compresses that.

Cryptographic changes have a large blast radius.

Changes can affect key formats, serialization, stored data, APIs, external systems, certificates, and application behavior.

02 — The Solution

One workflow from discovery to verified migration.

Find

Discover cryptography in source code. Quantera identifies things such as:

  • RSA, ECDSA, ECDH
  • AES, key size, curve, provider
  • Source location and caller relationships

Understand

Determine what the cryptography actually protects — for example:

RSA-2048/OAEP protects an AES-256 data-encryption key used by CustomerVaultService.

ApplicationRSAAES KeyCustomer Records

Migrate

Generate controlled post-quantum code changes for supported patterns — for example RSA key protection to ML-KEM, or RSA digital signatures to ML-DSA.

Migration decisions are policy-controlled rather than chosen freely by an AI model.

Verify

Prove the migration still works: build, existing tests, generated PQC tests, behavioral tests, rescan, compatibility checks, unexpected-file checks, performance measurement.

Additional migration recipes and environments are added only after they meet Quantera's verification requirements.

Cryptographic Inventory

Build a cryptographic inventory you can actually act on.

Quantera can produce repository-level cryptographic information including algorithm, variant, purpose, operation, key size, curve, provider, file, class, method, caller relationships, protected asset, destination, quantum status, migration status, and verification status.

Who It's For

Built for software organizations facing cryptographic modernization.

Federal software contractors

Software suppliers preparing for government and customer PQC requirements.

Cybersecurity & infrastructure vendors

Products containing cryptographic dependencies across complex software estates.

Fintech & regulated SaaS

Organizations protecting long-lived sensitive information and operating under security and compliance pressure.

Application Security & Engineering teams

Teams responsible for translating crypto findings into actual software changes.

Engineering Leverage

Migrate more software with the engineering team you already have.

Quantera automates repeatable migration work so engineers can spend more time reviewing architecture and making decisions.

Quantera workflow

Reduce manual analysis

Automate cryptographic discovery and dependency tracing.

Reduce remediation effort

Generate supported migration changes instead of starting from a blank editor.

Reduce verification work

Automatically execute builds, tests, rescans, and evidence collection.

Why Now

The post-quantum transition has moved from research to implementation.

NIST's PQC standards are finalized — FIPS 203 and FIPS 204 were ratified in 2024. Federal migration planning is underway, with U.S. federal systems targeted to move off RSA by 2035. Organizations need crypto inventories, and software estates take years to migrate. Long-lived sensitive information creates urgency: an average enterprise repository carries hundreds of crypto call sites.

The migration needs to begin before cryptographically relevant quantum computers arrive, not after.

Trust & Security

Your source code deserves more protection than a typical AI prompt.

Controlled AI

AI helps classify application context but does not independently choose migration algorithms.

Policy-controlled migrations

Supported recipes determine what Quantera can change.

Isolated verification

Builds and tests can run inside hardened, ephemeral environments.

Human approval

Quantera generates reviewable changes. Engineers retain merge control.

Auditability

Scans, migrations, verification runs, and evidence are recorded.

Source privacy

We're finalizing our source-retention and model-handling policy — full detail will publish on a dedicated Security page.
