spl-tls-analyze 0.3.2b0

Fast, zero-dependency TLS risk analysis with OCSP revocation detection and structured decisions

SPL TLS Risk Analyzer

Fast, zero-dependency TLS risk analysis with OCSP revocation detection and structured decisions.

Probes domains for TLS certificate validity, checks OCSP revocation, detects deprecated protocols (TLS 1.0/1.1), and produces ALLOW/REVIEW/DENY decisions across 20 risk categories with 5 severity levels. 3 operating profiles. JSON + Markdown structured output.

Beta software. Use for TLS risk assessment and CI guardrails; not a complete security audit.

Install

pip install spl-tls-analyze

Or install from source:

cd spl_v7_project_with_frontier/spl_v7_project
python scripts/spl_tls_analyze.py example.com

Docker image available: see docs/DOCKER_USAGE.md.

What It Does

• TLS probing — certificate validity, expiry, chain trust, protocol version via Python ssl
• OCSP revocation checking — AIA responder URL extraction + OCSP staple verification
• Deprecated TLS detection — secondary probe forces TLS 1.0 negotiation to detect legacy support
• 20 risk categories — VALID_TLS, EXPIRED_CERT, REVOKED_CERT, SELF_SIGNED_CERT, WRONG_HOST_CERT, UNTRUSTED_CHAIN, INCOMPLETE_CHAIN, WEAK_SIGNATURE_ALGORITHM, WEAK_CIPHER_SUITE, STATIC_RSA_KEY_EXCHANGE, TLS_COMPRESSION_ENABLED, WILDCARD_CERTIFICATE, MISSING_OCSP_STAPLE, DNS_FAILURE, CONNECTION_ERROR, TIMEOUT, TLS_HANDSHAKE_FAILURE, OCSP_UNREACHABLE, UNKNOWN_SSL_ERROR, DEPRECATED_TLS_VERSION
• 5 severity levels — NONE -> LOW -> MEDIUM -> HIGH -> CRITICAL
• 3 operating profiles — conservative, balanced (default), strict
• 3 output formats — structured console text, JSON (with schema), Markdown
• Zero external dependencies — stdlib only (Python 3.10+)
• Batch analysis — domain list files with progress reporting

Limitations

• No multi-IP or IPv6 probing
• Beta software — see docs/KNOWN_LIMITATIONS.md
• SPL evidence pipeline (--spl flag) requires optional [spl-core] extras

Quickstart

# Install
pip install spl-tls-analyze

# Analyze a single domain
spl-tls-analyze example.com

# Batch analysis with strict profile, JSON output
spl-tls-analyze domains.txt --profile strict --json-out report.json

# Markdown report with conservative profile
spl-tls-analyze domains.txt --profile conservative --markdown-out report.md

# Quiet mode — batch summary only
spl-tls-analyze domains.txt --quiet

Python 3.10+.

Profiles

Profile	ALLOW Threshold	HIGH Security	Deprecated TLS	Fallback ALLOW	Use Case
balanced (default)	0.5	REVIEW	REVIEW	Clean VALID_TLS only	General-purpose
conservative	0.7	REVIEW	REVIEW	Never	High-sensitivity
strict	0.7	DENY	DENY	Never	Security-critical

Exit Codes

Code	Meaning
0	All domains ALLOW
1	One or more REVIEW (no DENY)
2	One or more DENY
3	All domains errored
4	Invalid arguments

Dogfood Results

See docs/DOGFOOD_FINDINGS.md for results of running the CLI against 31 real public domains. Key findings:

• 31/31 domains probed, 0 errors, 0 timeouts
• After Phase 13 fallback: 19 ALLOW, 11 REVIEW, 1 DENY
• Before Phase 13: 0 ALLOW, 30 REVIEW, 1 DENY (fallback was missing)
• wrong.host.badssl.com correctly DENY'd
• revoked.badssl.com correctly detected as REVOKED_CERT — OCSP checking now implemented
• deprecated TLS detected (e.g. TLSv1.1) — secondary probe forces lower version negotiation
• Exit code 2 (DENY) clearly signals action needed
• Fallback ALLOW is adapter-policy based, not SPL confidence — see docs/CLI_CONFIDENCE_FALLBACK_POLICY.md

The CLI is now practical for routine scanning (exit code 0 fires for clean domains).
