Decast ID Manager

🔒 Decast DID Authentication Extension
A secure Chrome Extension enabling decentralized identity (DID) authentication for the Decast platform. Manage your Ed25519-based DIDs, sign nonces, and control your encrypted private keys – all in one simple, user-friendly interface.

🔐 Overview of Core Functionality
✅ Key Features
🟢 Generate cryptographic DID identities using Ed25519 keys
🟢 Manage and view existing identities
🟢 Sign nonces for secure authentication with Decast
🟢 Encrypt and restore keys using a password
🟢 Backup and securely store identities offline

🔄 Login Flow with Decast
Here’s how the extension works with decast.live:

1️⃣ Click "Login with DID" on the Decast website
2️⃣ A popup from the extension appears
🔸 Enter your password
🔸 Select a DID
3️⃣ The website fetches a nonce
4️⃣ The extension prompts for user confirmation
5️⃣ You confirm, the nonce is signed, and the signature is returned to the website
6️⃣ Login complete

🛡 Security Best Practices
🔐 Private keys are AES-encrypted with a password you define
🔐 The extension never stores or transmits your password
🔐 DID backups must be kept secure – treat them like wallet seed phrases
🔐 All sensitive actions, such as nonce signing, require explicit user confirmation
