PassShield: Cryptographic Vault

Securely generate strong passwords and encrypt your logins in an offline local vault using military-grade cryptography.

PassShield is an ultra-secure, 100% offline local cryptographic vault and password generator designed to protect your credentials without sending them to any third-party cloud. Features: - 🔑 **Cryptographic Password Generator**: Instantly generate random, cryptographically secure passwords. Adjust length (8 to 64 chars) and tweak inclusion rules (uppercase, lowercase, numbers, symbols) with immediate strength evaluation. - 🔐 **PBKDF2 Key Derivation**: Uses industrial-standard PBKDF2 with 100,000 SHA-256 iterations to derive your symmetric AES-GCM encryption key from your master password. - 🛡️ **AES-GCM Encryption**: Your credentials list is encrypted client-side using standard AES-GCM prior to storage inside your local browser. - 🔒 **Zero Server Access**: Your master password and decrypted logins list remain strictly in-memory and are never stored or uploaded. If you close the popup, the derived keys are instantly destroyed from RAM. - ⚡ **One-Click Autofill**: Easily copy credentials, delete vault accounts, or autofill generated passwords into the credential creation fields. Reclaim your privacy and secure your accounts offline. Privacy Note: PassShield values your privacy. Your vault databases and settings are processed entirely on-device (offline)—your passwords and usernames are never transmitted over network calls. The extension is 100% free.
