key-management SKILL.md skillA
key-management from hermeticormus/libresecops-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hermeticormus/libresecops-claude-code/key-management@git:20260930.71a2663Pins git:20260930.71a2663 in mdr.lock. Pin the fingerprint instead.

Key management reference: key lifecycle and types, storage security hierarchy, rotation strategy, envelope encryption, crypto-shredding, KMS access control, and anti-patterns such as keys in source code. Use when designing how keys are stored, rotated, or destroyed.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Key Management
> Key lifecycle management, rotation strategies, storage options, and operational security for cryptographic keys.
## Knowledge Base
### Key Lifecycle
Every cryptographic key goes through a lifecycle. Each phase has security requirements:
```
Generation → Distribution → Storage → Use → Rotation → Revocation → Destruction
| | | | | | |
v v v v v v v
CSPRNG Secure channel Encrypted Audit New key Notify Crypto-
or HSM or KMS API at rest trail replaces relying shred
old parties
```
### Key Types and Their Roles
| Key Type | Abbreviation | Purpose | Lifecycle |
|----------|-------------|---------|-----------|
| **Master Key** | MK | Protects other keys. Never used for data directly. | Years. Stored in HSM. Rarely rotated. |
| **Key Encryption Key** | KEK | Encrypts Data Encryption Keys (envelope encryption). | Months to years. Stored in KMS. |

How to install
mdr add hermeticormus/libresecops-claude-code/key-management@sha256:e367dc1b19b5e538The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
