services / Azure / Azure Key Vault keys

A cryptographic key stored in an Azure Key Vault (software- or HSM-protected). These keys are used for encryption, decryption, signing, key wrapping, and as customer-managed encryption keys (CMK) protecting downstream services and data.

Key Vault keys are among the most sensitive assets in a cloud tenant: they underpin envelope encryption, disk/storage/database encryption, and code/token signing. Private key material is non-exportable via normal reads, so the headline risk varies sharply by operation (read vs. crypto-oracle vs. export).

Verifies a signature against the key. For asymmetric keys this can be performed with only read access to the public portion, and on its own only confirms signature validity rather than exposing new material.

Risks

1. Metadata discovery (LOW)

Scope: LOW

This privilege allows access to data that are not meant to be public, but are otherwise not sensitive.
