QuantaSeek PQC TLS Scanner 🔍

QuantaSeek is a production-ready Post-Quantum Cryptography (PQC) aware TLS scanner that performs real TLS handshakes using rustls, analyzes TLS/PQC features, and produces structured, explainable security and performance reports.

✨ Key Highlights

✅ Real TLS Handshakes: Uses rustls for actual TLS 1.3/1.2 connections
✅ 100% Accurate Certificate Analysis: RFC 6125 compliant hostname validation, no mock data
✅ PQC Detection: Supports ML-KEM (Kyber), Dilithium, Falcon, SPHINCS+
✅ QUIC Support: Certificate extraction via TLS 1.2 fallback with robust retry logic
✅ Transparent Scoring: Explainable security scores with detailed formulas
✅ Production Ready: High accuracy for certificate validation, comprehensive error handling

🌟 Key Features

🔐 PQC Algorithm Detection

KEMs: ML-KEM-512 (L1), ML-KEM-768 (L3), ML-KEM-1024 (L5) — Kyber aliases supported
Hybrid Mode: Classical + PQC combinations (e.g., X25519 + ML-KEM-768)
PQC Signatures (analysis): Dilithium2/3/5, Falcon512/1024, SPHINCS+ (via certificate OID analysis)
Raw TLS Parsing: Extracts cipher suites and key exchange algorithms directly from ServerHello messages

📊 Transparent Security Scoring

Multi-Component Analysis: TLS (30%), Certificate (25%), PQC (45%) for PQC-enabled handshakes
Classical Mode: TLS (50%), Certificate (50%) for classical-only connections
Explainability: Exact formulas and sub-scores included in JSON output
NIST Mapping: FIPS 203 levels (L1/L3/L5) reflected in scores

Batch Scans: Summary stats and per-target analysis
TLS 1.2 Fallback: Automatic certificate extraction for QUIC connections
QUIC Support: Robust TCP/TLS fallback with retry logic and multiple port attempts
No Mock Data: 100% real certificate data, validated and verified
Error Handling: Comprehensive error reporting with detailed diagnostics

🎯 Client Profiles

Classic: Standard TLS 1.3 with classical algorithms only
Fallback: Cloudflare PQC-enabled server profile with fallback support
Hybrid: Hybrid PQC with classical fallback
MaxPQC: PQC-only configuration (experimental)

📄 Features, Capabilities, and Limitations (full document)

A complete description of all features, capabilities, and limitations of this Rust project is available in FEATURES_AND_LIMITATIONS.md (in English). It covers:

Features: Real TLS handshakes, PQC detection (KEM and certificate-based), client profiles and fallback, certificate analysis (RFC 6125), security scoring, QUIC support, HTTP redirect detection, performance timing, output formats, and CLI options.
Capabilities: Single and batch scans, dual stack (TCP + QUIC), fallback chains, structured output, and library API.
Limitations: QUIC certificate extraction (TLS 1.2 fallback only; QUIC-only servers may have no cert/key_exchange), TLS 1.3 encrypted fields (CertificateVerify), PQC detection gaps (empty raw_server_hello, parsing issues), HTTP redirect and network behaviour, code quality (unwrap/panic, logging), no config file, and test coverage.
TLS 1.3 vs QUIC reporting: PQC key exchange is reported for both TLS 1.3 and QUIC where available; PQC signature usage is authoritative for TLS 1.3 TCP (via CapturingVerifier) and best-effort for QUIC (certificate OID or "Not Implemented" when no cert).

📋 Command Line Options

USAGE:
    quantaseek [OPTIONS] <targets>...

ARGS:
    <targets>...    Target hostnames (e.g., example.com:443, google.com)

OPTIONS:
    -p, --profile <profile>
            Handshake profile to use [default: cloudflare-pqc]
            [possible values: standard, cloudflare-pqc, hybrid-pqc, pqc-only]

    -f, --format <format>
            Output format [default: json]
            [possible values: json, text]

        --tls12
            Enable TLS 1.2 fallback for certificate analysis

        --ignore-mismatch
            Ignore hostname mismatch for experimental servers

    -q, --quiet
            Suppress banner, progress lines, and summary; only print result (JSON/text).
            Use in production or scripts to avoid cluttering stdout.

    -v, --verbose
            Enable debug and progress messages (QUIC fallback, HTTP redirect, etc.).
            Equivalent to setting QUANTASEEK_DEBUG=1.

    -h, --help
            Print help information

    -V, --version
            Print version information

Production use and logging

By default the scanner prints a banner, per-target progress (Scanning: ..., ✅ Completed), and a summary. Debug messages (HTTP redirect, QUIC fallback) are off unless requested.

Production / scripts: use -q / --quiet so only the result (e.g. JSON) is printed; no banner or summary. Example: ./target/release/quantaseek -q example.com google.com > out.jsonl
Debug: use -v / --verbose, or set QUANTASEEK_DEBUG=1, to enable [DEBUG] and [QUIC Fallback] messages on stderr. This avoids flooding the terminal in production.

🔍 Technical Details

TLS Handshake Process

Connection Establishment: TCP connection to target server (default port 443)
TLS Handshake: Real TLS 1.3 handshake using rustls with selected profile
Raw Record Capture: Captures raw TLS records including ServerHello for analysis
Certificate Extraction: Extracts and validates X.509 certificates
PQC Detection: Analyzes key exchange algorithms and extensions for PQC support
Security Scoring: Calculates multi-component security scores with explainable formulas

QUIC Support

For QUIC-enabled servers:

Automatic detection of QUIC-capable servers
TCP/TLS fallback with robust retry logic (minimum 3 attempts)
Multiple port attempts (443, actual_port, 8443)
Extended timeout (minimum 8 seconds) for rate-limited servers
Detailed logging for fallback attempts
Certificate extraction via TLS 1.2 fallback when needed

Certificate Analysis

RFC 6125 Compliance: Strict hostname validation
Algorithm Consistency: Validates public key and signature algorithm consistency
OID Extraction: Extracts signature algorithm OIDs for PQC detection
SAN Parsing: Parses Subject Alternative Names for multi-domain certificates
Validity Checking: Validates certificate expiration dates
No Mock Data: 100% real certificate data from actual handshakes

PQC Detection Methods

Key Exchange Analysis: Detects PQC KEM groups in key_share extension
Certificate OID Analysis: Identifies PQC signature algorithms via certificate OIDs
Raw TLS Parsing: Extracts cipher suites and groups directly from ServerHello
Extension Analysis: Analyzes supported_groups and key_share extensions

🧪 Testing & Validation

Test Results

Based on comprehensive testing with 60+ servers:

Success Rate: 83.3% (50/60 successful scans)
Cipher Suite Extraction: 75% success rate
PQC Detection: 25% of servers show PQC support
Profile Consistency: 100% correct profile names in successful scans
Certificate Accuracy: 100% real certificate data, no mock data

Known Limitations

TLS 1.3 Encryption: CertificateVerify signature algorithms are encrypted in TLS 1.3, reported as "Unknown"
QUIC certificate extraction: Certificate and key exchange for QUIC are obtained via TCP/TLS 1.2 fallback only; direct extraction from the QUIC connection is not implemented. QUIC-only servers may show no certificate or key_exchange
QUIC-Only Servers: Some QUIC-only servers do not offer TCP/TLS on the same host/port; certificate and PQC detection will be unavailable for those targets
Rate Limiting: Some servers may rate-limit connections, causing occasional failures
Network Errors: Network connectivity issues may cause scan failures (reported with proper error messages)
Empty raw_server_hello: Classic profile or some fallback paths do not capture raw ServerHello, so raw parsing–based PQC detection is unavailable for those scans
