CredHub is a Cloud Foundry component for centrally managing credentials — passwords, certificates, SSH keys, RSA keys, and arbitrary values — across the lifecycle of an application or platform.
Instead of secrets living in config files, environment variables, or app manifests, CredHub stores them in one place and exposes an API to generate, retrieve, update, and delete them, along with fine-grained permissions on who can access each credential.

CredHub is primarily used to:
