SecureShards is a secure, client-side web application that allows users to split sensitive information into multiple encrypted pieces (shards) using Shamir's Secret Sharing algorithm. This provides an additional layer of security beyond traditional password managers or cloud storage solutions.
- Split & Recover: Split secrets into multiple encrypted shards and recover them when needed
- Threshold-Based Security: Specify how many shards are required to reconstruct the secret
- Client-Side Processing: All encryption and processing happens in your browser
- Multiple Export Formats: Export shards as text files or QR codes
- Password Protection: Additional encryption layer using user-provided passwords
- Drag & Drop Interface: Easy file handling for shard recovery
First, run the development server:
npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun devOpen http://localhost:3000 with your browser to see the result.
