SM Remote Crypto Service

Module

SmRemote

Status

VERIFIED

Description

Dedicated remote service for Chinese SM2/SM3/SM4 cryptographic operations, running as an independent microservice.

Implementation Details

  • Service Entry Point: src/SmRemote/StellaOps.SmRemote.Service/Program.cs -- ASP.NET Core minimal API service exposing /status, /health, /sign, /verify, /hash, /encrypt, and /decrypt.
  • SmRemote Integration Tests: src/SmRemote/__Tests/StellaOps.SmRemote.Service.Tests/SmRemoteServiceApiTests.cs -- endpoint-level integration coverage for positive and negative paths.
  • Docker Compose Overlay: devops/compose/docker-compose.sm-remote.yml -- overlay configuration for running SM Remote alongside the base platform compose stack.

E2E Test Plan

  • Start the SM Remote service and verify /health and /status return success responses.
  • Submit an SM3 hash request with known test input and verify digest output from /hash.
  • Submit an SM2 signing request and verify the returned signature via /verify.
  • Submit an SM4 encryption request, then decrypt the ciphertext via /decrypt, and verify the round-trip matches the original plaintext.
  • Verify negative-path validation for invalid hash payloads, invalid SM4 key lengths, and invalid sign input (HTTP 400 responses).
  • Confirm compose overlay contract remains documented for alongside-platform deployment (devops/compose/docker-compose.sm-remote.yml).
