🔐 Security Tool

Text Encryption

Encrypt and decrypt text with AES-256-GCM and a password. Nothing leaves your browser.

⚠️ Password is never stored or sent anywhere. If you lose the password the text CANNOT be recovered.

How This Text Encryption Tool Works

This tool uses AES-256-GCM, the same encryption standard trusted by banks, governments, and messaging apps. Your password is first strengthened with PBKDF2 (310,000 rounds of SHA-256 hashing plus a random salt), which turns even a simple password into a strong 256-bit encryption key and makes brute-force guessing extremely slow. The GCM mode also adds a built-in integrity check, so if the encrypted text is modified or the wrong password is used, decryption simply fails instead of producing garbage.

Everything Stays in Your Browser

All encryption and decryption happens locally using your browser's built-in Web Crypto API. Your text, your password, and the encrypted result never leave your device — there is no server, no account, and no logging. A fresh random salt and IV are generated for every encryption, so encrypting the same text twice produces completely different output.

Common Use Cases

Protect passwords, private notes, API keys, or personal messages before saving them in cloud notes, emails, or chat apps. Share sensitive text over an insecure channel and give the password separately. Because the output is a single portable text string, you can paste it anywhere — and only someone with the password can ever read it.
