What does the revocation feature in Vault do?

The revocation feature in Vault is designed to remove access to secrets that are no longer valid. This is a critical aspect of maintaining security, as it ensures that any credentials, tokens, or access policies that are no longer needed or are deemed insecure can be invalidated, preventing unauthorized access to sensitive data.

When a secret is revoked, any associated tokens or leases are also terminated, effectively cutting off access for any user or service relying on that secret. This becomes particularly important in scenarios where credentials may have been exposed or when a user leaves an organization, as it helps mitigate risks and enforce least privilege access.

Other options do not align with the primary function of revocation. For example, while storing credentials securely is vital, it is not the focus of the revocation feature. Granting additional permissions or generating new credentials automatically also falls outside the scope of revocation, which specifically deals with the invalidation of access rights rather than the expansion or creation of them.
