xxd -r -p grpc_frame.hex | protoc --decode_raw | sed -E 's/([0-9]+:[[:space:]]*")[^"]+(")/\1[REDACTED_PROTO_FIELD]\2/g'⚠️ Why Naive CLI / Regex Fails: Running sed on raw binary Protobuf frames corrupts Varint length-delimited (wire type 2) byte counts, while sed on protoc --decode_raw output indiscriminately wipes non-sensitive enum/status strings and misses nested submessage octets (\342\200...) containing Bearer tokens.
🛡️ Pre-LLM & Ticket Safety: How to decode and sanitize a Protobuf binary wire payload or protoc --decode_raw dump before pasting into ChatGPT, Claude, or Cursor or sharing in a gRPC vendor ticket
Core capabilities built into ProtobufWireShield
Inspects and redacts sensitive UTF-8 strings (JWTs, sk_live_* keys, emails) inside Protobuf field tags without requiring your proprietary .proto schema files.
Retains exact field numbers (1:, 2 {, 15:), wire types, and numeric status codes so gRPC wire mismatches and unknown-field bugs remain 100% diagnosable.
Strips grpc-metadata-authorization headers, x-api-key trailers, and embedded TLS session tokens captured alongside binary gRPC frames.
Eliminate GH013 and Gitleaks blocks on gRPC wire test vectors and safely debug binary serialization bugs in Claude or ChatGPT.
Zero configuration, zero cloud server dependencies, instant execution.
Paste schema-less protoc --decode_raw outputs, gRPC-Web Base64 frames, or hex wire captures directly into local browser memory.
Wire-aware tokenizers identify length-delimited strings containing Bearer JWTs, API keys, emails, and credit card numbers while preserving field tags and varints.

Even without a .proto schema, any online Protobuf decoder runs protoc --decode_raw on the server, immediately extracting every length-delimited UTF-8 string—including live Bearer JWTs, session cookies, customer emails, and payment tokens.
Protobuf wire type 2 (length-delimited strings and submessages) prefixes every field with a base-128 Varint byte length. If a regex changes the string length by even 1 byte without recalculating parent submessage Varints, every downstream parser fails.
Secret scanners detect Base64/UTF-8 JWTs, sk_live_* keys, and AWS credentials inside protoc text dumps and gRPC replay files. ProtobufWireShield replaces sensitive string literals with deterministic redacted placeholders while keeping field numbers intact.
No. ProtobufWireShield operates directly on schema-less protoc --decode_raw outputs, grpcurl traces, and wire dumps 100% locally in your browser.
Never. All wire tag parsing, token masking, and Canvas field-density visualization execute 100% inside your browser's local RAM with zero network egress.
