📄 Description

Summary

Add Blindfold as a LangChain integration provider. Blindfold is a PII detection and protection gateway for AI applications — it detects sensitive data (names, emails, phone numbers, addresses, SSNs, and more) across 18+ languages and replaces it with reversible tokens.

The langchain-blindfold package (already published on PyPI) provides:

  • BlindfoldPIITransformer — Document transformer for protecting PII in RAG pipelines and vector stores
  • BlindfoldTokenizer / BlindfoldDetokenizer — Runnables for composing PII protection into any LangChain chain
  • blindfold_protect() — Convenience factory for paired tokenizer/detokenizer

Files added/modified

  • src/oss/python/integrations/providers/blindfold.mdx — Provider page with overview and setup
  • src/oss/python/integrations/document_transformers/blindfold.mdx — Document transformer page with usage examples for all 6 PII methods (tokenize, redact, mask, hash, synthesize, encrypt), detection policies, region support, and chain composition
  • src/oss/python/integrations/providers/all_providers.mdx — Added Card entry in alphabetical order

Checklist

  • Code examples have been tested and work correctly
  • Used root relative paths for internal links
