Square's Keywhiz secret management system is another dedicated service used to provide general security for sensitive data. Like Vault, Keywhiz exposes APIs that clients and users can use to store and access secrets. One unique feature that Keywhiz offers is the ability to expose secrets using a FUSE filesystem, a virtual filesystem that clients can mount to access the sensitive data as pseudo-files. This mechanism allows many different types of programs to access the data they need without the help of an agent or wrapper and it allows administrators to lock down access using normal Unix filesystem permissions.
