* feat(guardrails): add prebuilt credential patterns for JWT, and OpenAI, Anthropic, Gemini API keys * fix(guardrails): prevent quadratic backtracking in jwt_token pattern * test(guardrails): move credential pattern tests into test_patterns.py * feat(guardrails): remove jwt_token to keep credential patterns strictly bounded * fix(guardrails): mask whole provider keys and keep openai_api_key to OpenAI's key shapes End each pattern so a key ending in "-" is masked in full, require OpenAI's T3BlbkFJ marker on bare sk- keys so other vendors' sk- keys and LiteLLM virtual keys are left alone, add sk-None- user keys, and replace the registration-only tests with whole-match, length-boundary, and negative cases * fix(guardrails): require the T3BlbkFJ marker on every OpenAI key form and match keys after escaped separators openai_api_key now needs the marker on the sk-proj-, sk-svcacct-, sk-admin- and sk-None- forms too, as gitleaks and TruffleHog do. anthropic_api_key and gemini_api_key also start a match right after a literal \n or \t or a percent-encoded byte, so keys in pasted JSON strings and URL-encoded logs are masked. * fix(guardrails): bound the OpenAI key regex, match Gemini prefixes case-sensitively, and hold back long keys in streamed replies * fix(guardrails): size the streaming holdback per pattern, stop OpenAI key tails before the next key, and allow non-ASCII text after a key * fix(guardrails): mask content filter pattern matches found in the original text so overlapping patterns cannot split a key * fix(guardrails): let a block pattern see the text after earlier masking patterns, as before Masking patterns still match the original text and merge overlapping matches into one tag, but a BLOCK pattern checks the text with the masking patterns listed before it applied, so a request main masked and passed is not blocked now. Detections name only the patterns whose tag was written. * fix(guardrails): keep content filter masks in order and hold back the longest OpenAI key Masking patterns run in configured order on the masked text as on main, so a contextual pattern still matches next to an earlier tag, and each also matches the original text so an earlier tag cannot split a key. Detections follow the configured pattern, not its name, and the OpenAI streaming holdback covers the pattern's 419-character longest match. --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> |
