# Azure Key Vault Secrets (Java)

Securely store and manage secrets like passwords, API keys, and connection strings.

## Installation

```xml
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-security-keyvault-secrets</artifactId>
    <version>4.9.0</version>
</dependency>
```

## Client Creation

```java
import com.azure.core.credential.TokenCredential;
import com.azure.identity.AzureIdentityEnvVars;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.identity.ManagedIdentityCredentialBuilder;
import com.azure.security.keyvault.secrets.SecretClient;
import com.azure.security.keyvault.secrets.SecretClientBuilder;

// Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
TokenCredential credential = new DefaultAzureCredentialBuilder()
    .requireEnvVars(AzureIdentityEnvVars.AZURE_TOKEN_CREDENTIALS)
    .build();
// Or use a specific credential directly in production:
// See https://learn.microsoft.com/java/api/overview/azure/identity-readme?view=azure-java-stable#credential-classes
// TokenCredential credential = new ManagedIdentityCredentialBuilder().build();

// Sync client
SecretClient secretClient = new SecretClientBuilder()
    .vaultUrl("https://<vault-name>.vault.azure.net")
    .credential(credential)
    .buildClient();

// Async client
SecretAsyncClient secretAsyncClient = new SecretClientBuilder()
    .vaultUrl("https://<vault-name>.vault.azure.net")
    .credential(credential)
    .buildAsyncClient();
```

## Create/Set Secret

```java
import com.azure.security.keyvault.secrets.models.KeyVaultSecret;

// Simple secret
KeyVaultSecret secret = secretClient.setSecret("database-password", "P@ssw0rd123!");
System.out.println("Secret name: " + secret.getName());
System.out.println("Secret ID: " + secret.getId());

// Secret with options
KeyVaultSecret secretWithOptions = secretClient.setSecret(
    new KeyVaultSecret("api-key", "sk_live_abc123xyz")
        .setProperties(new SecretProperties()
            .setContentType("application/json")
            .setExpiresOn(OffsetDateTime.now().plusYears(1))
            .setNotBefore(OffsetDateTime.now())
            .setEnabled(true)
            .setTags(Map.of(
                "environment", "production",
                "service", "payment-api"
            ))
        )
);
```

## Get Secret

```java
// Get latest version
KeyVaultSecret secret = secretClient.getSecret("database-password");
String value = secret.getValue();
System.out.println("Secret value: " + value);

// Get specific version
KeyVaultSecret specificVersion = secretClient.getSecret("database-password", "<version-id>");

// Get only properties (no value)
SecretProperties props = secretClient.getSecret("database-password").getProperties();
System.out.println("Enabled: " + props.isEnabled());
System.out.println("Created: " + props.getCreatedOn());
```

## Update Secret Properties

```java
// Get secret
KeyVaultSecret secret = secretClient.getSecret("api-key");

// Update properties (cannot update value - create new version instead)
secret.getProperties()
    .setEnabled(false)
    .setExpiresOn(OffsetDateTime.now().plusMonths(6))
    .setTags(Map.of("status", "rotating"));

SecretProperties updated = secretClient.updateSecretProperties(secret.getProperties());
System.out.println("Updated: " + updated.getUpdatedOn());
```

## List Secrets

```java
import com.azure.core.util.paging.PagedIterable;
import com.azure.security.keyvault.secrets.models.SecretProperties;

// List all secrets (properties only, no values)
for (SecretProperties secretProps : secretClient.listPropertiesOfSecrets()) {
    System.out.println("Secret: " + secretProps.getName());
    System.out.println("  Enabled: " + secretProps.isEnabled());
    System.out.println("  Created: " + secretProps.getCreatedOn());
    System.out.println("  Content-Type: " + secretProps.getContentType());
    
    // Get value if needed
    if (secretProps.isEnabled()) {
