What encryption algorithm does this tool use?

The tool uses AES-256-CBC, a globally recognized symmetric encryption standard.

What happens if I forget my passphrase?

The encrypted text cannot be recovered without the passphrase. Store it securely in a password manager.

Does the tool send my text to a server?

No. All encryption and decryption happens locally in your browser. Neither plaintext nor ciphertext is transmitted anywhere.

Is this suitable for enterprise or compliance use?

This tool is not a replacement for professional cryptographic consultation or enterprise security solutions. For compliance-driven requirements, consult a specialist.

Can I decrypt the text on a different device?

Yes. As long as you have the ciphertext and the correct passphrase, you can decrypt it on any device using this tool.

Yes, completely free with no registration required.

Is there a size limit for the text I can encrypt?

There is no enforced limit beyond browser memory constraints, which comfortably covers any practical use case.

Text Encrypt Tool - AES-256 Browser-Based Encryption

⚠️ This tool is ENCODING, not ENCRYPTION. Base64/ROT13/URL/HEX/Binary are all reversible and provide no privacy. For sensitive data, use AES-256-grade tools (e.g. our Password Generator plus a password manager).
