Advanced AES encryption tool for files and text with ZIP support. Encrypt multiple files or text with AES-256, manage keys securely, and download encrypted content as ZIP archives. Perfect for securing sensitive documents and communications.

How It Works

1

Choose Operation Mode

Select whether to encrypt or decrypt data, and choose AES key size (128, 192, or 256 bits) and cipher mode.

2

Provide Key and Data

Enter your encryption key (or generate a secure one) and input the text or upload files you want to encrypt/decrypt.

3

Process and Download

The tool performs AES encryption/decryption locally and provides the result for download or copying.

Frequently Asked Questions

What is AES encryption?

AES (Advanced Encryption Standard) is a symmetric encryption algorithm used worldwide for securing sensitive data. It's the same encryption standard used by governments and banks for protecting classified information.

Which AES key size should I use?

AES-256 offers the highest security and is recommended for most use cases. AES-128 is faster but less secure. AES-192 is a middle ground but less commonly used.

How should I manage my encryption keys?

Keep encryption keys secure and separate from encrypted data. Use strong, randomly generated keys and consider using a password manager or secure key storage system.

Is my data secure during encryption?

Yes, all encryption and decryption happens locally in your browser. Your data, keys, and encrypted content never leave your device or get transmitted to servers.

Can I encrypt files as well as text?

Yes, the tool supports both text encryption and file encryption. You can encrypt documents, images, and other file types using AES encryption.

What happens if I lose my encryption key?

Without the correct key, AES-encrypted data cannot be recovered. Always backup your encryption keys securely and separately from your encrypted data.
