| Encryption | R4 says vault field values are end-to-end encrypted and decrypted locally; vault names, item names, field labels, and website metadata are not end-to-end encrypted. | The backend uses AES-256-GCM envelope encryption with a random data key per secret value, and the documentation says plaintext secret values are never stored in the database. |
| Support | The site links to a support center and lists a contact email. | The repository directs vulnerability reports to a private GitHub security advisory and says not to disclose exploitable issues publicly. |

In their own words
Secrets Manager
Secrets Manager is a free, open-source, self-hosted system for storing application secrets in encrypted form, managing them through a web interface, and injecting them into processes with a command-line tool. Users organize secrets by organization, project, and environment, import.env files, edit or reveal values, keep versions, roll back, and soft-delete entries. The `secrets run` command supplies environment secrets to a child process and its descendants without creating a.env file. Documented workflows cover Node.js, Python, npm, and Next.js; CI or deployment can use an API URL, token, and environment ID. User and service-account grants can be scoped to projects or environments, and revealing values requires explicit permission. AES-256-GCM envelope encryption uses a separate data key per value, while plaintext values are not stored in the database. Audit events include secret reveals, and values are withheld if audit writing fails. Docker Compose starts PostgreSQL, Redis, backend, and frontend; local Kubernetes manifests are also provided. A user-generated master key is mandatory and lost keys make secrets unrecoverable. The repository is MIT licensed.
