Encrypt / Decrypt Message

About this tool

Encrypt a message with a passphrase, then share the generated link. The recipient can use the same passphrase to decrypt your message. The encrypted data is stored entirely in the URL — nothing is sent to any server.

Features

• Client-side encryption using AES-GCM
• No data sent to servers — everything stays in the URL
• Passphrase-based key derivation using PBKDF2
• Secure random salt and IV for each encryption

How it works

1. Enter your message and a passphrase
2. Click "Encrypt" to generate a shareable link
3. Send the link to your recipient
4. They enter the passphrase to decrypt the message
