ClipCrab

A lightweight and secure clipboard manager built with Tauri and Rust.

Features

• 📋 Clipboard History - Automatically saves everything you copy
• 🔍 Search - Quickly find items in your history
• 📌 Pin Items - Keep important items at the top
• 🔄 Auto-start - Launch with your system
• 🔐 Encrypted Storage - All data is encrypted at rest

Security

ClipCrab takes your privacy seriously. All clipboard data is encrypted before being stored on disk.

Encryption Method

• Algorithm: AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode)
• Key Size: 256-bit
• Nonce: 12-byte random nonce for each encryption
• Key Storage: A unique encryption key is automatically generated and stored locally on first launch
• Encoding: Encrypted data is Base64 encoded for safe storage

AES-256-GCM provides both confidentiality and authenticity, ensuring your clipboard data cannot be read or tampered with without the encryption key.
