# 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 ## Reference Links | Resource | Link | |----------|------| | API Reference | https://docs.rs/azure_security_keyvault_secrets | | Source Code | https://github.com/Azure/azure-sdk-for-rust/tree/main/sdk/keyvault/azure_security_keyvault_secrets | | crates.io | https://crates.io/crates/azure_security_keyvault_secrets | ## When to Use Azure Key Vault Secrets SDK for Rust.
