Encrypt Text with AES | Secure Your Private Messages 🔐

Protect sensitive notes and private messages using the industry-standard AES algorithm. Only those with the correct password can unlock your content.

💡 Why Use This Tool?

Stop sending plain-text passwords over DM or storing sensitive info in unencrypted notes. This tool adds a layer of military-grade security to your digital communications.

100% Client-Side Privacy: Your data never leaves your device. All encryption and decryption happen locally in your browser. We never see your text, and we never store your passwords.

📘 How to Use: Real-time & Secure

1. Encrypt (Sender)

1. Select "Encrypt Text": Ensure the "Encrypt Text" button is active.
2. Enter Text: Type your private message in the top box.
3. Set Password: Enter a password in the "Password (Secret Key)" field. The encrypted text will automatically appear in the "Result" box below.

2. Decrypt (Receiver)

1. Select "Decrypt Text": Click the "Decrypt Text" button to switch modes.
2. Paste Encrypted Text: Paste the garbled text into the top box.
3. Enter Password: Type the password you were given. The original message will instantly reappear below.

💡 Pro Tips

• Create a Strong Password: Decryption requires an exact match. Use a combination of letters, numbers, and symbols to ensure your data remains uncrackable.
• Generate Shareable Links: Create a URL that contains your encrypted data. For maximum security, send the link via one app and the password via a different, encrypted channel.
• Save Secure Backups: Download your encrypted results as a .txt file. This allows you to keep "blind" backups on cloud drives without risking exposure.
• Leave No Trace: Because this tool is browser-based, nothing is saved to a database. Close the tab to wipe the session.

🧐 Frequently Asked Questions

Q. Can I recover my text if I forget the password? A. No. To ensure total security, there is no back door. Without the password, the data is mathematically impossible to recover within a practical timeframe.

Q. Is it safe to use on public computers? A. While the tool doesn't send data to a server, "Share Links" may appear in your browser history. Always use Incognito or Private mode on shared devices.

Q. What is the character limit? A. There is no limit for standard encryption. However, most web browsers limit "Share Links" to approximately 2,000 characters.

📚 The Tech Behind the Tool

AES (Advanced Encryption Standard) was established by NIST in 2001. Originally called "Rijndael," it was designed by two Belgian cryptographers to secure electronic data for governments and banks worldwide.

To crack a 128-bit AES key via brute force, it would take the world’s fastest supercomputer billions of years. It remains the global gold standard for data security.
