Text Encryptor
Encrypt and decrypt text messages with AES-256-GCM encryption. Share encrypted messages securely - all processing happens in your browser.
Choose a strong password. You'll need it to decrypt.
How It Works
- • Your password is converted to a key using PBKDF2
- • Text is encrypted with AES-256-GCM
- • Output includes salt and IV for decryption
- • Each encryption produces unique output
🔒 Privacy First: All encryption happens in your browser using the Web Crypto API. Your text and password never leave your device.
How to Use
- Select Encrypt or Decrypt mode
- Enter your text or paste encrypted text
- Enter a password (minimum 4 characters)
- Click the Encrypt/Decrypt button
- Copy the result and share (password separately)
About Text Encryption
This tool uses AES-256-GCM encryption, the same standard used by governments and financial institutions. The password is converted to an encryption key using PBKDF2 with 100,000 iterations, making brute-force attacks impractical.
Each encryption uses a unique random salt and initialization vector (IV), so encrypting the same text twice produces completely different outputs. This prevents pattern analysis and ensures maximum security.
Frequently Asked Questions
How do I share an encrypted message?
After encrypting your message, copy the encrypted text (Base64 format) and share it through any channel - email, messaging apps, etc. Share the password separately through a different channel for security. The recipient can use this same tool to decrypt it.
Is text encryption secure?
Yes, this tool uses AES-256-GCM encryption, the same standard used by governments and banks. Combined with PBKDF2 key derivation (100,000 iterations), your messages are protected by military-grade encryption that would take billions of years to crack.
Can encrypted messages be decrypted without the password?
No, without the correct password, the encrypted message cannot be recovered. AES-256 encryption is considered unbreakable with current technology. Always share passwords through secure channels and never include them with the encrypted message.
Is my message stored anywhere?
No, all encryption and decryption happens in your browser using JavaScript. Your messages and passwords are never sent to any server, stored, or logged. When you close or refresh the page, everything is gone.
Why does the encrypted output look random?
The encrypted output is encoded in Base64 format, which uses letters, numbers, and symbols. It contains the encrypted data plus metadata (salt and IV) needed for decryption. Each encryption produces different output even for the same message.
Can I encrypt long messages or entire documents?
Yes, you can encrypt text of any length. However, for large documents or files, consider using our File Encryptor tool instead, which is optimized for handling larger data more efficiently.
