## What it does

The skill equips the assistant with code patterns for the `azure_security_keyvault_keys` crate. It steers the model through `KeyClient` setup, handling RSA, EC, and HSM keys, as well as paginating properties using `Pager<T>`. It also includes patterns for envelope encryption with wrap and unwrap calls where private keys stay inside Azure Key Vault.

The Rust Azure SDK lacks `DefaultAzureCredential`. Because of that, the skill enforces `DeveloperToolsCredential` for local environments and `ManagedIdentityCredential` for production. All operations need the `AZURE_KEYVAULT_URL` environment variable. It also instructs the agent to install dependencies via `cargo add` instead of manual edits to `Cargo.toml`.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-keyvault-keys-rust -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-keyvault-keys-rust/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-keyvault-keys-rust/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-keyvault-keys-rust/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-keyvault-keys-rust/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-keyvault-keys-rust
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-keyvault-keys-rust/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-sdk-rust/skills/azure-keyvault-keys-rust
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-keyvault-keys-rust/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-sdk-rust/skills/azure-keyvault-keys-rust/SKILL.md

## When to use it
- create RSA, EC, or HSM-protected keys in Azure Key Vault using Rust
- wrap and unwrap symmetric data encryption keys for envelope encryption
- configure credential flows without unsupported DefaultAzureCredential types
- iterate through Key Vault key properties using Pager<T>

## Example prompts
- Write a Rust snippet to create an EC P-256 key in Key Vault using KeyClient
- Implement DEK wrapping with RSA-OAEP-256 in Rust via Azure Key Vault
- Show how to list key properties with pagination in Rust

# Azure Key Vault Keys library for Rust

Secure storage and management of cryptographic keys — RSA, EC, and HSM-protected.

Use this skill when:

- An app needs to create or manage cryptographic keys in Key Vault from Rust
- You need to wrap/unwrap data encryption keys (envelope encryption)
- You need to sign or verify data with Key Vault keys
- You need HSM-protected keys

> **IMPORTANT:** Only use the official `azure_security_keyvault_keys` crate published by the [azure-sdk](https://crates.io/users/azure-sdk) crates.io user. Do NOT use unofficial or community crates. Official crates use underscores in names and none have version 0.21.0.

## Installation

```sh
cargo add azure_security_keyvault_keys azure_identity tokio futures
```

> If your code uses `azure_core` types directly, add `azure_core` to `Cargo.toml`. If you only use `azure_security_keyvault_keys` re-exports, direct `azure_core` dependency is optional.

## Environment Variables

```bash
AZURE_KEYVAULT_URL=https://<vault-name>.vault.azure.net/ # Required for all operations
```

## Authentication

Rust Azure SDK code must not use `DefaultAzureCredential`. The Rust identity crate does not provide that type.

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

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Local dev: DeveloperToolsCredential. Production: use ManagedIdentityCredential.
    let credential = DeveloperToolsCredential::new(None)?;
    let client = KeyClient::new(
        "https://<vault-name>.vault.azure.net/",
        credential.clone(),
        None,
    )?;

    let key = client.get_key("key-name", None).await?.into_model()?;
    println!("Key: {:?}", key.key);
    Ok(())
}
```

Prefer the crate README/examples when checking public operation shapes such as key creation, wrapping, and version-aware unwrap flows.

## Core Workflow

### Create Key

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

// Create an EC key
let body = CreateKeyParameters {
    kty: Some(KeyType::Ec),
    curve: Some(CurveName::P256),
    ..Default::default()
};

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

println!(
    "Name: {:?}, Type: {:?}, Version: {:?}",
    key.resource_id()?.name,
    key.key.as_ref().map(|k| k.kty.as_ref()),
    key.resource_id()?.version,
);
```

### Update Key Properties

```rust
use azure_security_keyvault_keys::models::UpdateKeyPropertiesParameters;
use std::collections::HashMap;

#[allow(clippy::needless_update)]
let params = UpdateKeyPropertiesParameters {
    tags: Some(HashMap::from_iter(vec![("env".into(), "prod".into())])),
    ..Default::default()
};

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