Security Notes
Client-Side Processing
All encryption and decryption happens locally in your browser. Your text and keys never leave your device.
Key Security
Use strong, unique keys. Store your keys securely - losing your key means losing access to encrypted data.
Production Use
For sensitive data, consider using established encryption libraries and proper key management systems.
How to Use Text Encryption
Choose Mode
Select whether you want to encrypt or decrypt text, then configure encryption settings.
Set Key
Enter your encryption key or generate a secure one. Use the same key for decryption.
Process Text
Enter your text and click encrypt or decrypt. Copy or download the result.
AES Encryption
Industry-standard AES encryption with multiple modes and key sizes
Key Management
Generate secure keys, derive from passwords, or import/export keys
Multiple Modes
Support for CBC, CFB, OFB, and CTR encryption modes
Client-Side Only
All processing happens locally - your data never leaves your browser
🔒 What is AES Encryption?
Advanced Encryption Standard (AES) is a symmetric encryption algorithm established by the U.S. National Institute of Standards and Technology. It's widely used worldwide for protecting sensitive data and is considered highly secure when properly implemented.
🔐 How It Works
Our tool uses AES encryption with multiple modes (ECB, CBC, CFB, OFB, CTR) and supports 128, 192, and 256-bit key lengths. All encryption happens locally in your browser using the Web Crypto API, ensuring your data never leaves your device.
🛡️ Security & Privacy
Your text and passwords are processed entirely client-side using JavaScript. Nothing is sent to our servers, logged, or stored anywhere. This ensures complete privacy and security for your sensitive information.
🎯 Use Cases
Perfect for encrypting personal notes, passwords, sensitive documents, or any text you want to keep secure. The encrypted output is base64-encoded for easy copying and storage in databases or text files.
📝 How to Use Text Encryption
Enter Text
Type or paste the text you want to encrypt in the input area. Supports any text content including special characters.
Set Password
Enter a strong password that will be used to encrypt your text. Remember this password - you'll need it to decrypt.
Choose Options
Select encryption mode (CBC recommended) and key size (256-bit for maximum security).
Encrypt & Copy
Click encrypt to generate the secure text. Copy the result and store it safely. Use the same password to decrypt later.
