KeyVault

A simple WPF credential manager to store API keys securely. It supports creating a PIN-protected vault, encrypting secrets, and basic CRUD operations for entries.

Prerequisites

• .NET SDK 8.0 (or compatible)
• Windows (WPF app)

Getting Started

Run the app

1. Restore and build:
   • dotnet build KeyVault/KeyVault.csproj
2. Start the application:
   • dotnet run --project KeyVault/KeyVault.csproj

First run (Create PIN)

• On first launch, you’ll be prompted to create a vault PIN.
• Enter and confirm the PIN, then select Create Vault.
• You’ll be navigated to the main window once creation succeeds.

Add / Edit API keys

• Click the + button in the header to add a new API key.
• Double-click a row to edit an existing key.

Clipboard auto-clear

• Copying a secret to the clipboard will auto-clear after 60 seconds.

Notes

• Vault database file is stored under %APPDATA%/KeyVault/vault.db.
• The app uses a session key derived from the PIN to encrypt/decrypt secrets.

Development

• Project path: KeyVault/KeyVault.csproj
• Useful commands:
  • dotnet build KeyVault/KeyVault.csproj
  • dotnet run --project KeyVault/KeyVault.csproj
