cage (Client-side age Encryption) is a secure file viewer/editor for age encrypted files.

Features: - Auto-detection of age files based on file extension (.age) - Client-side encryption/decryption using the age standard - Passphrase-based encryption with scrypt key derivation - Auto-lock timer to protect sensitive data - Mnemonic passphrase generation - Zero server-side access to plaintext content

Security: - All encryption/decryption happens in the browser - Passphrase stored in memory only, never sent to server - Auto-lock clears passphrase and removes decrypted content from DOM
