Frequently Asked Questions about E2EE_KeyStorage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I securely store private keys locally for end-to-end encryption?▼

Securely store private keys locally by saving them in IndexedDB. This approach keeps cryptographic keys isolated in the browser, providing a secure foundation for digital signatures and end-to-end encrypted messaging applications.

How do I share public keys using Supabase for secure messaging?▼

Share public keys by uploading them directly to a Supabase table. This enables key discovery among users, allowing applications to retrieve public keys for secure communication and digital signature verification.

Can I use IndexedDB for cryptographic key management in web applications?▼

Yes, you can use IndexedDB for cryptographic key management. This Skill stores private keys locally in IndexedDB while uploading public keys to Supabase, creating a complete key infrastructure for web apps.

What is the best way to manage end-to-end encryption keys for digital signatures?▼

The best way to manage end-to-end encryption keys is retaining private keys locally in IndexedDB and publishing public keys to a centralized Supabase table, streamlining key distribution and digital signature workflows.

Does this key storage approach require a backend server to function?▼

This key storage approach requires Supabase as a backend to store and share public keys, while private cryptographic keys remain securely stored locally in the browser's IndexedDB to ensure end-to-end encryption integrity.
