# SM Soft Crypto Plugin Charter

## Mission
Provide software-only SM2/SM3 signing and hashing for StellaOps cryptography.

## Responsibilities
- Keep key handling deterministic and explicit.
- Gate software SM usage via environment controls.
- Avoid exposing private key material.
- Track task status in `TASKS.md`.

## Required Reading
- `docs/modules/platform/architecture-overview.md`

## Working Agreement
- 1. Update task status in the sprint file and local `TASKS.md`.
- 2. Validate key options and algorithm IDs explicitly.
- 3. Add tests for env gate behavior and key-loading error paths.
