Key Vault Keys — Rust SDK Quick Reference

Condensed from azure-keyvault-keys-rust. Full patterns (EC keys, backup/restore, crypto operations, RBAC permissions) in the azure-keyvault-keys-rust plugin skill if installed.

Install

cargo add azuresecuritykeyvaultkeys azureidentity

Quick Start

use azure_identity::DeveloperToolsCredential;
use azure_security_keyvault_keys::KeyClient;
let credential = DeveloperToolsCredential::new(None)?;
let client = KeyClient::new("https://<vault>.vault.azure.net/", credential.clone(), None)?;

Best Practices

• Use Entra ID auth — DeveloperToolsCredential for dev, ManagedIdentityCredential for production
• Use HSM keys for sensitive workloads — hardware-protected keys
• Use EC for signing — more efficient than RSA
• Use RSA for encryption — when encrypting data
• Backup keys for disaster recovery
• Enable soft delete — required for production vaults
• Use key rotation — create new versions periodically

Non-Obvious Patterns

use azure_security_keyvault_keys::models::{CreateKeyParameters, KeyType};
let params = CreateKeyParameters { kty: KeyType::Rsa, key_size: Some(2048), ..Default::default() };
client.create_key("name", params.try_into()?, None).await?.into_model()?;
