From 359e3c4af21065ece0e7927ef33ed8d09839be51 Mon Sep 17 00:00:00 2001 From: khyari hamza Date: Tue, 17 Feb 2026 12:38:39 +0000 Subject: [PATCH 1/4] chore: WIP branch for feat(security): add secrets masking and validation Refs: H-21, SEC5.secrets Planned: Day 13 -- 2.52.0 From d815339c52afdd7a2aac97904f6f361890755f4d Mon Sep 17 00:00:00 2001 From: khyari hamza Date: Tue, 17 Feb 2026 16:01:40 +0000 Subject: [PATCH 2/4] feat(security): add secrets masking and validation (H-21/SEC5) Implement centralized redaction utility that masks API keys, tokens, and credentials across CLI output, structlog logs, and error messages. - Add shared/redaction.py with pattern-based secret detection (sk-*, sk-ant-*, tok_*, Bearer tokens), sensitive key name detection, database URL masking, custom pattern registration, and thread-safe global show_secrets flag - Add config/logging.py with structlog configuration integrating the secrets_masking_processor into the processor chain - Add --show-secrets global CLI option to reveal secrets when needed - Redact error details in main.py, project.py, and auto_debug.py error handlers before printing - Wrap format_output() in formatting.py with automatic dict redaction - Add show_secrets field and safe __repr__ to Settings model - Add 43-scenario Behave feature (features/security_secrets.feature) - Add 10 Robot Framework smoke tests (robot/security_secrets.robot) - Add ASV benchmarks (benchmarks/security_secrets_bench.py) - Add reference docs (docs/reference/secrets_handling.md) --- benchmarks/security_secrets_bench.py | 108 +++++++ docs/reference/secrets_handling.md | 112 +++++++ features/security_secrets.feature | 188 ++++++++++++ features/steps/security_secrets_steps.py | 320 ++++++++++++++++++++ robot/security_secrets.robot | 74 +++++ src/cleveragents/cli/commands/auto_debug.py | 7 +- src/cleveragents/cli/commands/project.py | 7 +- src/cleveragents/cli/formatting.py | 26 +- src/cleveragents/cli/main.py | 22 +- src/cleveragents/config/logging.py | 94 ++++++ src/cleveragents/config/settings.py | 20 ++ src/cleveragents/shared/__init__.py | 25 +- src/cleveragents/shared/redaction.py | 265 ++++++++++++++++ 13 files changed, 1256 insertions(+), 12 deletions(-) create mode 100644 benchmarks/security_secrets_bench.py create mode 100644 docs/reference/secrets_handling.md create mode 100644 features/security_secrets.feature create mode 100644 features/steps/security_secrets_steps.py create mode 100644 robot/security_secrets.robot create mode 100644 src/cleveragents/config/logging.py create mode 100644 src/cleveragents/shared/redaction.py diff --git a/benchmarks/security_secrets_bench.py b/benchmarks/security_secrets_bench.py new file mode 100644 index 000000000..3d9c589ce --- /dev/null +++ b/benchmarks/security_secrets_bench.py @@ -0,0 +1,108 @@ +"""ASV benchmarks for SEC5 secrets redaction throughput. + +Measures the performance of the core redaction functions to ensure +masking overhead stays within acceptable bounds. +""" + +from __future__ import annotations + +import importlib +import sys +from pathlib import Path + +# Ensure the local *source* tree is importable even when ASV has an +# older build of the package installed. +_SRC = str(Path(__file__).resolve().parents[1] / "src") +if _SRC not in sys.path: + sys.path.insert(0, _SRC) + +import cleveragents # noqa: E402 + +importlib.reload(cleveragents) + +from cleveragents.shared.redaction import ( # noqa: E402 + is_sensitive_key, + mask_database_url, + redact_dict, + redact_value, + secrets_masking_processor, +) + +# ── Sample data ─────────────────────────────────────────────────── + +_SECRET_STRING = "My API key is sk-proj-abc123def456ghi789jkl012mno345" +_CLEAN_STRING = "This is a perfectly normal log message with no secrets" +_MIXED_DICT: dict[str, object] = { + "api_key": "sk-proj-abc123def456ghi789", + "username": "alice", + "password": "hunter2", + "config": { + "token": "tok_01HXYZ1234567890ABCDEF", + "endpoint": "https://api.example.com", + }, + "message": "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWI", +} +_POSTGRES_URL = "postgresql://admin:s3cret@db.prod.internal:5432/mydb" +_SQLITE_URL = "sqlite:///data/cleveragents.db" + + +# ── Benchmarks ──────────────────────────────────────────────────── + + +class RedactValue: + """Benchmark ``redact_value`` for secret and clean strings.""" + + def time_redact_secret_string(self) -> None: + redact_value(_SECRET_STRING) + + def time_redact_clean_string(self) -> None: + redact_value(_CLEAN_STRING) + + def time_redact_empty_string(self) -> None: + redact_value("") + + +class RedactDict: + """Benchmark ``redact_dict`` for nested dicts.""" + + def time_redact_mixed_dict(self) -> None: + redact_dict(_MIXED_DICT) # type: ignore[arg-type] + + def time_redact_empty_dict(self) -> None: + redact_dict({}) + + +class IsSensitiveKey: + """Benchmark ``is_sensitive_key`` lookups.""" + + def time_sensitive_key(self) -> None: + is_sensitive_key("api_key") + + def time_non_sensitive_key(self) -> None: + is_sensitive_key("username") + + def time_false_positive_key(self) -> None: + is_sensitive_key("token_count") + + +class MaskDatabaseUrl: + """Benchmark ``mask_database_url`` for various URL schemes.""" + + def time_mask_postgres_url(self) -> None: + mask_database_url(_POSTGRES_URL) + + def time_mask_sqlite_url(self) -> None: + mask_database_url(_SQLITE_URL) + + +class StructlogProcessor: + """Benchmark the structlog masking processor.""" + + def time_processor_with_secrets(self) -> None: + event = dict(_MIXED_DICT) + event["event"] = "Request failed with key sk-ant-api03-xyz123abc456" + secrets_masking_processor(None, "info", event) + + def time_processor_clean_event(self) -> None: + event = {"event": "User logged in", "user": "alice", "status": "ok"} + secrets_masking_processor(None, "info", event) diff --git a/docs/reference/secrets_handling.md b/docs/reference/secrets_handling.md new file mode 100644 index 000000000..abccb2e1b --- /dev/null +++ b/docs/reference/secrets_handling.md @@ -0,0 +1,112 @@ +# Secrets Handling (SEC5) + +CleverAgents automatically masks API keys, tokens, and credentials in +CLI output, structured logs, and error messages.
