post-quantum-crypto-migrator

post-quantum-crypto-migrator is a skill for Cursor from roedyrustam/vibes-plug. It costs 64 tokens per session (2,302 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 5d 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.

Description

An advanced cryptographic engineering skill designed to future-proof FinTech, SaaS, and payment architectures (such as DOKU, Stripe, and banking APIs) against the "Harvest Now, Decrypt Later" (HNDL) quantum threat. It audits existing RSA (<3072-bit) and classical ECC (NIST P-256, secp256k1) implementations, systematically migrating them to NIST-standardized Post-Quantum Cryptography (FIPS 203 ML-KEM, FIPS 204 ML-DSA, and FIPS 205 SLH-DSA) using production-grade hybrid schemes.

Trigger Conditions

  • Security audits during Phase 6 or SOC2 / ISO 27001 readiness reviews.
  • Upgrading cryptographic primitives in payment gateways (doku-payment-gateway, saas-billing).
  • Explicit compliance requests for Quantum-Resistant Encryption or CNSA 2.0 standards.
  • Generating long-lived JWTs, mTLS certificates, or database encryption keys that must remain secure for 10+ years.

post-quantum-crypto-migrator is a skill published in the GitHub repository roedyrustam/vibes-plug (114 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 2,302 once invoked, about $0.0003 per session on Opus 5.5. 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.
