grpc-hmac-interceptor
JSON →Node.js library (v1.0.4) for adding HMAC authentication to gRPC applications via interceptors. Works with @grpc/grpc-js, supporting both @grpc/proto-loader and protoc-generated protos. Uses SHA512-256 HMAC with key ID and signature in metadata headers. Lightweight, TypeScript-first, and integrates as a gRPC interceptor without modifying service logic.
