# Export Crypto Prep — PREP-EXPORT-CRYPTO-90-001

Status: Draft (2025-11-20)
Owners: Exporter Service · Security Guild
Scope: Capture crypto requirements pending Nov-18 review and reference implementation.

## Needs
- Mapping of signing/encryption algorithms per export profile.
- Integration with `ICryptoProviderRegistry` (same as Evidence Locker) for provider selection.
- Hashing defaults (sha256) and optional sha512/sha3 for high-assurance paths.

## Open decisions
- Final provider list and key storage (KMS/HSM) per profile.
- Whether to sign both manifest and per-artifact hashes.

## Handoff
Use as prep artefact for EXPORT-CRYPTO-90-001; fill once Security delivers profile list and reference implementation.
