# Azure Key Vault Keys SDK for Rust

Client library for Azure Key Vault Keys — secure storage and management of cryptographic keys.

## Installation

```sh
cargo add azure_security_keyvault_keys azure_identity
```

## Environment Variables

```bash
AZURE_KEYVAULT_URL=https://<vault-name>.vault.azure.net/
```

## Authentication

```rust
use azure_identity::DeveloperToolsCredential;
use azure_security_keyvault_keys::KeyClient;

let credential = DeveloperToolsCredential::new(None)?;
let client = KeyClient::new(
    "https://<vault-name>.vault.azure.net/",
    credential.clone(),
    None,
)?;
```

## Key Types

| Type | Description |
|------|-------------|
| RSA | RSA keys (2048, 3072, 4096 bits) |
| EC | Elliptic curve keys (P-256, P-384, P-521) |
| RSA-HSM | HSM-protected RSA keys |
| EC-HSM | HSM-protected EC keys |

## Core Operations

### Get Key

```rust
let key = client
    .get_key("key-name", None)
    .await?
    .into_model()?;

println!("Key ID: {:?}", key.key.as_ref().map(|k| &k.kid));
```

### Create Key

```rust
use azure_security_keyvault_keys::models::{CreateKeyParameters, KeyType};

let params = CreateKeyParameters {
    kty: KeyType::Rsa,
    key_size: Some(2048),
    ..Default::default()
};

let key = client
    .create_key("key-name", params.try_into()?, None)
    .await?
    .into_model()?;
```

### Create EC Key

```rust
use azure_security_keyvault_keys::models::{CreateKeyParameters, KeyType, CurveName};

let params = CreateKeyParameters {
    kty: KeyType::Ec,
    curve: Some(CurveName::P256),
    ..Default::default()
};

let key = client
    .create_key("ec-key", params.try_into()?, None)
    .await?
    .into_model()?;
```

### Delete Key

```rust
client.delete_key("key-name", None).await?;
```

### List Keys

```rust
use azure_security_keyvault_keys::ResourceExt;
use futures::TryStreamExt;

let mut pager = client.list_key_properties(None)?.into_stream();
while let Some(key) = pager.try_next().await? {
    let name = key.resource_id()?.name;
    println!("Key: {}", name);
}
```

### Backup Key

```rust
let backup = client.backup_key("key-name", None).await?;
// Store backup.value safely
```

### Restore Key

```rust
use azure_security_keyvault_keys::models::RestoreKeyParameters;

let params = RestoreKeyParameters {
    key_bundle_backup: backup_bytes,
};

client.restore_key(params.try_into()?, None).await?;
```

## Cryptographic Operations

Key Vault can perform crypto operations without exposing the private key:

```rust
// For cryptographic operations, use the key's operations
// Available operations depend on key type and permissions:
// - encrypt/decrypt (RSA)
// - sign/verify (RSA, EC)
// - wrapKey/unwrapKey (RSA)
```

## Best Practices

1. **Use Entra ID auth** — `DeveloperToolsCredential` for dev, `ManagedIdentityCredential` for production
2. **Use HSM keys for sensitive workloads** — hardware-protected keys
3. **Use EC for signing** — more efficient than RSA
4. **Use RSA for encryption** — when encrypting data
5. **Backup keys** — for disaster recovery
6. **Enable soft delete** — required for production vaults
7. **Use key rotation** — create new versions periodically

## RBAC Permissions

Assign these Key Vault roles:
- `Key Vault Crypto User` — use keys for crypto operations
- `Key Vault Crypto Officer` — full CRUD on keys

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
