# SOPS Encryption

Encrypt secrets in configuration files while keeping structure visible.

## When to Use This Skill

Use this skill when:
- Encrypting secrets in Git
- Implementing GitOps with secrets
- Managing Kubernetes secrets as code
- Encrypting configuration files

## Prerequisites

- SOPS installed
- KMS access (AWS, GCP, Azure) or PGP key

## Installation

```bash
# macOS
brew install sops

# Linux
wget https://github.com/getsops/sops/releases/download/v3.8.0/sops-v3.8.0.linux.amd64
chmod +x sops-v3.8.0.linux.amd64
mv sops-v3.8.0.linux.amd64 /usr/local/bin/sops
```

## Basic Usage

```bash
# Encrypt with AWS KMS
sops --encrypt --kms arn:aws:kms:region:account:key/key-id secrets.yaml > secrets.enc.yaml

# Decrypt
sops --decrypt secrets.enc.yaml

# Edit encrypted file
sops secrets.enc.yaml

# Encrypt in place
sops --encrypt --in-place secrets.yaml
```

## Configuration

```yaml
# .sops.yaml
creation_rules:
  - path_regex: .*\.prod\.yaml$
    kms: arn:aws:kms:us-east-1:account:key/prod-key
  - path_regex: .*\.dev\.yaml$
    kms: arn:aws:kms:us-east-1:account:key/dev-key
  - path_regex: .*
    pgp: fingerprint
```

## Kubernetes Integration

```yaml
# encrypted secret
apiVersion: v1
kind: Secret
metadata:
  name: myapp-secrets
type: Opaque
stringData:
  password: ENC[AES256_GCM,data:encrypted...]
sops:
  kms:
    - arn: arn:aws:kms:region:account:key/key-id
```

```bash
# With ArgoCD
# Install ksops plugin for ArgoCD to decrypt secrets
```

## Best Practices

- Store .sops.yaml in repository
- Use different keys per environment
- Rotate encryption keys regularly
- Never commit unencrypted secrets
- Use key aliases for readability

- argocd-gitops (`argocd-gitops`) - GitOps integration

## Limitations

- Apply guidance only within authorized scope; test destructive steps in non-production first.
- Docs-only import: upstream scripts and templates not bundled.

### Example

```bash
# Read-only first: inventory before any active step.
which <tool> && <tool> --help | head -n 20
```
