EasyVault 0.1.1

EasyVault

Live: easyvault.belov.us - The key you enter will encrypt your secrets (Easy)

Lightweight, self‑contained Zero-Trust secrets service — a single Docker image with a built‑in Web UI. Run the container, open the UI, enter any encryption key and manage secrets without extra setup.

What's inside

• Single image, built‑in UI (served from the same server at /).
• AES‑256 (PBKDF2‑SHA256) at rest; only a SHA‑512 of the password is stored.
• Per‑secret IP and User‑Agent allowlists (wildcards supported).
• SQLite by default; migrations apply automatically.
• Health check at /api/v1/health.
• Minimal .NET SDK (Dictionary or typed mapping).

Quick start (UI‑first)

In Docker (locally):

# Build the image
docker build -t easyvault:local -f .\Sources\EasyVault.Server\Dockerfile .\Sources

# Run the container
docker run --name easyvault -p 8080:8080 -v easyvault_data:/data easyvault:local

# Open the UI
# Go to http://localhost:8080 and manage secrets from the admin panel.

Local run without Docker (optional):

cd .\Sources\EasyVault.Server
dotnet run

By default the server listens on 8080. The UI is available at /. DB path: /data/easyvault.db (for Docker).

Configuration (optional)

Settings in Sources/EasyVault.Server/appsettings.json:

{
  "SqliteConnectionString": "Data Source=/data/easyvault.db;Cache=Shared;Foreign Keys=True;Pooling=True;Mode=ReadWriteCreate;"
}

You can override these with ASP.NET Core environment variables.

API (brief)

1. Create/update vault (encrypt and save) — the UI does this for you:

POST /api/v1/vault/{password}
Content-Type: application/json

[
  {
    "keyId": "b7c1e6b6-4321-4c9c-1234-0bb2d6bf9b4a",
    "appName": "MyApp",
    "values": { "DB_PASSWORD": "supersecret", "API_TOKEN": "abcdef" },
    "allowedAddresses": ["127.0.0.1", "10.0.*"],
    "allowedUserAgents": ["PostmanRuntime", "MyService/*"]
  }
]

2. Get secrets by keyId (allowed by IP/UA; vault must be unsealed, the UI handles unseal):

GET /api/v1/vault/secrets/{keyId}?format=json|plain

• format=json — returns { "KEY": "VALUE" }.
• format=plain — returns strings like KEY=VALUE.

Also available: GET /api/v1/vault/{password} — decrypts the latest vault for this password and unseals in‑memory cache.

Note: the password ({password}) is used only for encryption/decryption and is not stored (only its SHA‑512 hash).

.NET SDK (optional)

Client usage example:

using EasyVault.SDK;

var client = new EasyVaultClient("http://localhost:8080", new Guid("b7c1e6b6-1234-4c9c-4321-0bb2d6bf9b4a"));

// Key-value dictionary
var map = client.GetSecrets();

// Typed mapping by property names (case-insensitive)
var typed = client.GetSecrets<MySecrets>();

public class MySecrets
{
    public string DB_PASSWORD { get; set; } = string.Empty;
    public string API_TOKEN { get; set; } = string.Empty;
}
