Azure Key Vault

Use Key Vault and you don’t need to provision, configure, patch, and maintain HSMs and key management software. Provision new vaults and keys (or import keys from your own HSMs) in minutes and centrally manage keys, secrets, and policies. You keep control over your keys—simply grant permission for your own and partner applications to use them as needed. Applications never have direct access to keys.

Improve performance and reduce the latency of your cloud applications by storing cryptographic keys in the cloud, instead of on-premises. Key Vault quickly scales to meet the cryptographic needs of your cloud applications and match peak demand, without the cost of deploying dedicated HSMs.
