This page lets you encrypt and decrypt text using AES‑CBC encryption with a secret key and IV. Everything happens in your browser using CryptoJS — nothing is sent anywhere.
Want a simple, powerful way to protect your text—without sending anything over the internet?
With our AES‑CBC tool, you can:
- Encrypt text: Turn any message into unreadable cipher text using strong AES‑CBC encryption.
- Decrypt text: Paste your encrypted data and your key to get the original message back instantly.
- Stay fully private: Everything happens 100% in your browser using CryptoJS. Your text, keys, and encrypted data never leave your device.
No installs, no accounts, no servers—just open the page, type, and lock down your data. Give it a spin and feel what it’s like to have serious encryption at your fingertips.
How to Use It
1. Open the page
Just open the tool in your browser.
2. Enter your plain text
Type or paste your text into the Plain Text box (top box).
3. Encrypt
Click Encrypt.
The Encrypted Text box (middle box) will show the AES‑CBC encrypted result, created using your secret key and IV.
4. Copy or save the encrypted text (optional)
You can copy the encrypted text if you want to store it or send it somewhere.
Only someone with the same key and IV can decrypt it.
5. Decrypt
To turn encrypted text back into readable text:
- Make sure the encrypted text is in the Encrypted Text box
- Click Decrypt
The Decrypted Value box (bottom box) will show the original text.
6. Check the result
The decrypted text should match the original plain text exactly.
