How to Use AES/DES Encrypt — Step by Step
- Paste or type text
Enter the text you want to encrypt in the input box.
- Choose algorithm & mode
Select AES or DES, then pick a mode (ECB / CBC). AES supports 128/192/256-bit keys.
- Set a secret key
Enter a passphrase. For AES-256, use a 32+ character key for maximum security.
- Encrypt / Decrypt
Click the button. The result appears instantly and can be copied or downloaded.
Use Cases for AES/DES Encrypt
Secure messaging
Encrypt sensitive text before sending over email or chat.
Password storage
Encrypt passwords locally before storing them in a file.
Learning & teaching
Experiment with classical encryption algorithms to understand how they work.
FAQ — AES/DES Encrypt Free Online Tool
Is AES-256 secure?
Yes. AES-256 is considered military-grade and is widely used by governments and financial institutions worldwide.
What is the difference between ECB and CBC?
ECB (Electronic Codebook) encrypts identical blocks identically — it leaks patterns. CBC (Cipher Block Chaining) XORs each block with the previous one, making it much more secure.
Does this tool store my data?
No. All encryption and decryption happens entirely in your browser. Nothing is uploaded to any server.
