🔐 CryptoPad — Obsidian Plugin

Encrypt and decrypt text inline using a keyboard shortcut. Powered by AES-GCM + PBKDF2 via the Web Crypto API. Everything runs client-side — nothing is sent anywhere.

Features

• Keyboard shortcuts influenced by vim to efficiently encrypt/decrypt your text
• Encrypt & Decrypt tabs in one modal
• Optional passphrase memory via plugin settings
• Works on desktop and mobile
• AES-256-GCM encryption with your passphrase
• PBKDF2-SHA256 key derivation (200,000 iterations)
• Random salt + IV per encryption — every ciphertext is unique

Installation

From source (development)

1. Clone / copy this folder into your vault under .obsidian/plugins/cryptopad/
2. Run:

   npm install
   npm run build
   

3. In Obsidian: Settings → Community Plugins → enable CryptoPad

Manual install (pre-built)

1. Copy manifest.json, main.js, and styles.css into .obsidian/plugins/cryptopad/
2. Reload Obsidian and enable the plugin in Community Plugins

Usage

Action	How
Open CryptoPad	Ctrl+Shift+E (Windows/Linux) / Cmd+Shift+E (Mac)
Encrypt	Type text → enter passphrase → click Encrypt
Decrypt	Switch to Decrypt tab → paste ciphertext → enter passphrase → click Decrypt
Copy result	Click 📋 Copy
Quick action	Ctrl+Enter / Cmd+Enter while focused in the textarea
Close modal	Escape

Customizing the Shortcut

Go to Settings → Hotkeys, search "CryptoPad", and set your preferred key combination.

Security Notes

• Passphrase is never transmitted — all operations are local
• If "Remember passphrase" is enabled, it's stored via Obsidian's saveData() in the plugin's data file inside your vault
• Each encryption generates a fresh random 16-byte salt and 12-byte IV
• Output format: base64(salt[16] || iv[12] || ciphertext)
• AES-GCM provides both confidentiality and integrity
