Proof Keys Studio¶

Proof Keys Studio is a focused web application for managing cryptographic key pairs and creating data integrity proofs. It provides a clean, modern interface for WebAuthn authentication, key management, and document signing.

Key Features¶

• WebAuthn Authentication: Passwordless authentication using passkeys, Touch ID, Face ID, Windows Hello, or security keys
• Anonymous Sessions: Quick access without registration using "ANONYMOUS" username
• Key Management: Create, organize, and upgrade EdDSA did:key keys
• DID Upgrading: Bind keys to did:web DIDs for persistent, resolvable identities
• Document Signing: Create W3C Data Integrity Proofs using the eddsa-jcs-2022 cryptosuite
• Proof Management: Store, organize, and share signed documents
• Activity Logging: Track all key and proof operations in a detailed activity log

What Can You Do?¶

• Create Keys: Generate cryptographic keys for signing documents
• Sign Documents: Create verifiable proofs on any document
• Manage Proofs: Store, organize, and share signed documents
• Track Activity: See everything you've done in one place
• Install as App: Add to your home screen for quick access (PWA)

Getting Started¶

1. Access the App: Scan the QR code or visit https://proof-keys.studio
2. Install as PWA: Add to your home screen for quick access (see Access Guide)
3. Sign in or Register: Use WebAuthn or anonymous session
4. Create Keys: Your default key is created automatically
5. Prepare Documents: Upload, paste, or scan QR codes
6. Create Proofs: Sign documents with your keys
7. Manage Proofs: Store, share, and organize signed documents

See the Quick Start Guide for detailed instructions.

User Guide¶

• Managing Keys: Create and manage your cryptographic keys
• Upgrading Keys: Bind keys to your user DID
• Creating Proofs: Sign documents with cryptographic proofs
• Managing Proofs: Download, share, and organize signed documents

User Types¶

WebAuthn Users¶

• Register with a free-form username
• Use platform authenticators or security keys
• Can create up to 5 keys
• Get a user DID: did:web:proof-keys.studio:user:{username}
• Full access to all features

Anonymous Users¶

• Type "ANONYMOUS" as username to bypass WebAuthn
• Limited to 1 key total
• No user DID (only did:key keys)
• Can sign out like regular users
• Useful for quick testing or temporary sessions

How It Works¶

• Keys: Cryptographic identities used to sign documents
• Proofs: Cryptographic signatures that prove a document is authentic
• DIDs: Unique identifiers for your keys (e.g., did:key:z6Mk... or did:web:proof-keys.studio:user:yourname)
• Verification: Anyone can verify your proofs using your key's public identifier

Privacy and Security¶

• No Passwords: WebAuthn eliminates password-related vulnerabilities
• Phishing Resistant: Credentials are bound to proof-keys.studio
• Client-Side Storage: Proofs stored in browser localStorage
• Secure Key Storage: Keys stored in Askar with proper encryption
• User Isolation: Each user's keys and proofs are isolated by owner_id

Browser Support¶

• Chrome/Edge: Full support (Windows, macOS, Linux, Android)
• Firefox: Full support (Windows, macOS, Linux, Android)
• Safari: Full support (macOS, iOS)
• Opera: Full support
