Secure service for creating, storing, and managing cryptographic keys used to encrypt and decrypt data in cloud applications.
Key Management Service handles all the encryption keys for your application so you don't have to worry about storing passwords or certificates securely.
All provide managed creation, storage, rotation, and access control for encryption keys. AWS KMS, Google Cloud KMS, and OCI Vault focus on key lifecycle and cryptographic operations; Azure Key Vault also commonly stores secrets and certificates alongside keys. Each integrates with the provider’s storage, database, and compute services for envelope encryption and centralized auditing.
