How to Encrypt Text with a Password
Encrypt sensitive text messages using a password. Only someone with the password can decrypt and read the original text.. This step-by-step guide walks you through the process using LevnTools Text Encryptor/Decryptor, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.
Enter the text to encrypt
Type or paste the sensitive text you want to protect. This could be a private message, password, API key, or any confidential information.
Set an encryption password
Enter a strong password that will be used to encrypt and decrypt the text. The recipient needs this exact password to read the message. Use a long, unique password for maximum security.
Encrypt the text
Click Encrypt to process the text using AES-256 encryption. The output is an encrypted string that looks like random characters and is unreadable without the password.
Share the encrypted text
Copy the encrypted text and send it through any channel (email, messaging, etc.). Share the password through a separate channel for security. The recipient pastes the encrypted text and enters the password to decrypt.
Pro Tips
- Always share the encryption password through a different channel than the encrypted message (e.g., text the password, email the encrypted text).
- Use a strong, unique password for each encrypted message.
- The encryption happens entirely in your browser. No data is sent to any server.
Common Issues & Fixes
Issue: The decryption fails with an error.
Fix: The password must be exactly the same as the one used for encryption. Check for extra spaces, capitalization, and invisible characters.
Issue: The encrypted text is much longer than the original.
Fix: This is normal. Encryption adds overhead including initialization vectors and padding. The longer output is expected.
