Azure Key Vault Secrets SDK for Rust

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

Installation

cargo add azure_security_keyvault_secrets azure_identity

Environment Variables

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

Authentication

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

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

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

Set Secret

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

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

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

List Secrets

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

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

• Use Entra ID auth — DeveloperToolsCredential for dev, ManagedIdentityCredential for production

• Use into_model()? — to deserialize responses

• Use ResourceExt trait — for extracting names from IDs

• Handle soft delete — deleted secrets can be recovered within retention period

• Set content type — helps identify secret format

• Use tags — for organizing and filtering secrets

• 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
