Secure Share

A simple browser tool to encrypt and decrypt text before sharing it.

It can be used to send passwords, API keys, or other sensitive data safely by encrypting the message with a passphrase.

All encryption happens locally in the browser using the Web Crypto API.
No data is sent to any server.

How it works

1. Enter the text you want to encrypt
2. Enter a passphrase
3. Click Encrypt
4. Send the encrypted text to the recipient
5. Send the passphrase separately
6. The recipient pastes the encrypted text and passphrase to decrypt it

Security

• AES-GCM encryption
• PBKDF2 key derivation
