PQC readiness score

mp3tomidi.art

High risk
36/ 100
  • Readiness indicator, not a security guarantee
  • Higher score = more PQC-ready
  • Based on TLS, certificate & key-exchange posture

Executive summary

PostQ scanned the public TLS endpoint for mp3tomidi.art and found 7 findings, including 3 high-priority items and 2 quantum-vulnerable algorithms in the externally visible cryptography. The overall readiness score is 36/100 (High risk).

This score is a readiness indicator based on externally observable TLS, certificate, and key-exchange posture — not a guarantee of security. A complete cryptographic inventory also covers internal services, cloud KMS/HSM keys, JWTs, and code-signing workflows.

Risk score breakdown

How is this scored? →

Weighted categories that make up the readiness score.

Certificate public key25/100

Leaf certificate uses a classical (RSA/EC) public key vulnerable to Shor's algorithm.

Certificate signature25/100

Certificate is signed with a classical signature algorithm.

Key exchange75/100

Key exchange includes a post-quantum or hybrid component.

TLS protocol100/100

Negotiated TLSv1.3.

Technical findings

Signing: ECDSA (256-bit)

HighQuantum-vulnerable

Signing

Certificate public key: ECDSA is broken by Shor's algorithm (elliptic curve discrete log problem)

mp3tomidi.art

What this means

A cryptographically relevant quantum computer running Shor's algorithm could break this primitive — forging signatures or decrypting traffic that is being recorded today (harvest-now, decrypt-later).

How to fix

Track this in your cryptographic inventory and plan migration toward ML-DSA (FIPS 204) as your verifier/ecosystem adds support.

Signing: ecdsa-with-SHA256

HighQuantum-vulnerable

Signing

Certificate signed with ECDSA, signature is quantum-vulnerable

mp3tomidi.art (certificate signature)

What this means

A cryptographically relevant quantum computer running Shor's algorithm could break this primitive — forging signatures or decrypting traffic that is being recorded today (harvest-now, decrypt-later).

How to fix

Track this in your cryptographic inventory and plan migration toward ML-DSA (FIPS 204) as your verifier/ecosystem adds support.

Symmetric encryption: AES-256-GCM

LowSymmetric (lower risk)

Symmetric encryption

TLS bulk encryption: AES-256 is quantum-resistant; Grover's reduces effective security to 128-bit, still sufficient

mp3tomidi.art

What this means

Symmetric ciphers are only weakened (not broken) by Grover's algorithm; a 256-bit key keeps a strong post-quantum security margin.

How to fix

Prefer 256-bit symmetric keys (e.g. AES-256-GCM, ChaCha20-Poly1305) to retain a strong post-quantum margin.

TLS configuration: TLSv1.3

LowUnknown

TLS configuration

How to fix

TLS 1.3 supports hybrid post-quantum key exchange — enable X25519MLKEM768 where supported

TLS configuration: TLS_AES_256_GCM_SHA384

HighQuantum-vulnerable

TLS configuration

Negotiated cipher suite: TLS_AES_256_GCM_SHA384 (TLSv1.3)

mp3tomidi.art

What this means

A cryptographically relevant quantum computer running Shor's algorithm could break this primitive — forging signatures or decrypting traffic that is being recorded today (harvest-now, decrypt-later).

How to fix

Track this algorithm in your cryptographic inventory and plan a hybrid or post-quantum replacement.

Key exchange: X25519MLKEM768

InfoPQ-ready

Key exchange

Server supports post-quantum key exchange: X25519MLKEM768. PQ-safe key agreement is available.

mp3tomidi.art

What this means

This is a NIST-standardised post-quantum algorithm and is not known to be broken by quantum attacks.

How to fix

No action required — this is already a post-quantum algorithm.

TLS configuration: HSTS

MediumQuantum-vulnerable

TLS configuration

No Strict-Transport-Security response header. Clients can be SSL-stripped on first connect; recommend `Strict-Transport-Security: max-age=63072000; includeSubDomains; preload`.

Recommended migration steps

  1. 1Add every certificate, key-exchange group, and signing key above to a tracked cryptographic inventory so migration can be prioritised.
  2. 2Where your client and verifier ecosystems support it, deploy hybrid key exchange (X25519 + ML-KEM) to defend against harvest-now, decrypt-later.
  3. 3Plan a path to ML-DSA (FIPS 204) signatures for certificates and code signing as CAs and tooling add support.
  4. 4No action required for HNDL exposure.
  5. 5Extend the inventory beyond public TLS to internal services, cloud KMS/HSM keys, JWTs, and code-signing workflows for full coverage.

Compliance & audit notes

This report can be attached as evidence for cryptographic-inventory requirements that increasingly appear in security reviews (e.g. NIST’s migration guidance, US OMB M-23-02, and emerging FedRAMP / SOC 2 expectations around crypto-agility). PostQ does not assert any compliance certification on your behalf; use this as supporting evidence within your own program.
