1. Purpose
This procedure governs the use of cryptographic procedures and the management of keys throughout the lifecycle. It operationalises the associated policy ({{LINK:R09}}).
2. Scope
Applies within the ISMS scope ({{ISMS_SCOPE_DESCRIPTION}}).
3. Trigger
New need for encryption/certificates; key renewal/revocation; change in the state of the art.
4. Inputs
- Permissible algorithms (BL-CRY-02)
- Protection need of the data
- Certificate/key inventory
5. Process
- Determine need & procedure: select permissible algorithms {{CRYPTO_ALGO}} (BL-CRY-02).
- Generate keys/certificates and distribute them securely (BL-CRY-05).
- Storage & access protection (separate storage, {{#if FLAG_CRYPTO_PKI}}PKI, {{/if}}authorisations).
- Ensure transmission protection: at least {{TLS_MIN}} (BL-CRY-01).
- Document renewal/revocation/destruction.

7. Result & evidence
Documented cryptography concept; traceable key/certificate lifecycle. Evidence is referenced in the central evidence register ({{LINK:NACHWEISREGISTER}}).
8. Key performance indicators (KPI)
- Share of compliant procedures/algorithms
- Expiring certificates without renewal
- Coverage of transport encryption
