post-quantum-crypto-migrator

post-quantum-crypto-migrator is a skill for Claude Code, Codex from roedyrustam/vibes-plug. It costs 64 tokens per session (997 once invoked), scanned A, original, MIT.

A security guide for finding older encryption in financial and SaaS code and moving it to standards designed to resist future quantum computers.

In plain words
What is it for?
Use it during security reviews or when updating payment gateways, JWTs, and session tokens for post-quantum cryptography.
Why use it?
It helps identify RSA and elliptic-curve encryption that could eventually be broken by quantum computers, while planning a transition that keeps older systems working.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

post-quantum-crypto-migrator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Post-Quantum Cryptography Migrator

English | Bahasa Indonesia


English

Description

An advanced security architect skill designed to future-proof FinTech, SaaS, and Payment integrations (such as DOKU) against the impending threat of Quantum Computers breaking classical encryption (RSA/ECC). It scans codebases for vulnerable cryptographic algorithms and migrates them to NIST-approved Post-Quantum Cryptography (PQC) algorithms, such as CRYSTALS-Kyber (for Key Encapsulation) and CRYSTALS-Dilithium/SPHINCS+ (for Digital Signatures).

Trigger Conditions

  • During security audits or Phase 6 (Automated Testing & Security Audit).
  • When upgrading high-security financial payment gateways or generating JWT/Session tokens.
  • Explicit user request to make the application "Quantum-Proof".

Operating Protocol

  1. Cryptographic Discovery: Audits all usage of crypto, bcrypt, RSA, ECDSA, and HMAC operations.
  2. Hybrid Migration Plan: Recommends hybrid implementations (combining classical ECC with PQC algorithms like Kyber-512) to comply with modern standards while maintaining backward compatibility.
  3. Implementation: Swaps vulnerable implementations with PQC-ready libraries (e.g., OQS - Open Quantum Safe, or modernized webcrypto wrappers supporting Kyber).
  4. Validation: Ensures the expanded key sizes and signature sizes of PQC algorithms do not break database schemas or HTTP header limits.

Orchestration & Integration

  • Enforces extreme security standards alongside authentication-identity-expert.
  • Hardens doku-payment-gateway and saas-billing payload encryption to banking-grade PQC standards.
  • Integrates with database-orm-expert to update schema lengths (PQC keys are significantly larger than RSA).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

post-quantum-crypto-migrator is a skill published in the GitHub repository roedyrustam/vibes-plug (50 stars, last pushed 2d ago), licensed MIT. It adds 64 tokens to every session and 997 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
