# Azure Key Vault Secrets SDK for Rust

Client library for Azure Key Vault Secrets — secure storage for passwords, API keys, and other secrets.

## Installation

```sh
cargo add azure_security_keyvault_secrets azure_identity
```

## Environment Variables

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

## Authentication

```rust
use azure_identity::DeveloperToolsCredential;
use azure_security_keyvault_secrets::SecretClient;

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

## Core Operations

### Get Secret

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

println!("Secret value: {:?}", secret.value);
```

### Set Secret

```rust
use azure_security_keyvault_secrets::models::SetSecretParameters;

let params = SetSecretParameters {
    value: Some("secret-value".into()),
    ..Default::default()
};

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

### Update Secret Properties

```rust
use azure_security_keyvault_secrets::models::UpdateSecretPropertiesParameters;
use std::collections::HashMap;

let params = UpdateSecretPropertiesParameters {
    content_type: Some("text/plain".into()),
    tags: Some(HashMap::from([("env".into(), "prod".into())])),
    ..Default::default()
};

client
    .update_secret_properties("secret-name", params.try_into()?, None)
    .await?;
```

### Delete Secret

```rust
client.delete_secret("secret-name", None).await?;
```

### List Secrets

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

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

### Get Specific Version

```rust
use azure_security_keyvault_secrets::models::SecretClientGetSecretOptions;

let options = SecretClientGetSecretOptions {
    secret_version: Some("version-id".into()),
    ..Default::default()
};

let secret = client
    .get_secret("secret-name", Some(options))
    .await?
    .into_model()?;
```

## Best Practices

1. **Use Entra ID auth** — `DeveloperToolsCredential` for dev, `ManagedIdentityCredential` for production
2. **Use `into_model()?`** — to deserialize responses
3. **Use `ResourceExt` trait** — for extracting names from IDs
4. **Handle soft delete** — deleted secrets can be recovered within retention period
5. **Set content type** — helps identify secret format
6. **Use tags** — for organizing and filtering secrets
7. **Version secrets** — new values create new versions automatically

## RBAC Permissions

Assign these Key Vault roles:
- `Key Vault Secrets User` — get and list
- `Key Vault Secrets Officer` — full CRUD
