Text Encryption & Decryption Tool - Secure Your Messages

Our Text Encryption/Decryption Tool provides military-grade AES-256 encryption to secure your sensitive messages, notes, and data. Encrypt text with a password and decrypt it later - all processing happens locally in your browser for maximum privacy.

How Text Encryption Works

Text encryption converts readable plain text into unreadable ciphertext using cryptographic algorithms. Here's how our tool works:

Password-Based Encryption

Your password is used to generate a cryptographic key using PBKDF2 (Password-Based Key Derivation Function 2), which adds thousands of iterations to prevent brute-force attacks.

AES-256 Encryption

The actual encryption uses AES-256 (Advanced Encryption Standard with 256-bit keys) in CBC (Cipher Block Chaining) mode, which is the same standard used by governments and financial institutions.

Random Initialization Vector

Each encryption generates a random IV (Initialization Vector), ensuring that encrypting the same text with the same password produces different ciphertext each time, enhancing security.

Secure Output Format

The encrypted output is encoded in base64 format, making it safe to copy, paste, and share across different platforms without corruption.

Common Use Cases for Text Encryption

  1. Secure Message Sharing - Send encrypted messages via email or messaging apps
  2. Password Storage - Encrypt sensitive information before storing it
  3. Confidential Notes - Keep private notes and diaries secure
  4. API Keys & Credentials - Encrypt sensitive credentials for storage
  5. Personal Information - Protect personal data like addresses, phone numbers
  6. Business Secrets - Secure proprietary information and trade secrets
  7. Code Snippets - Protect sensitive code or configuration data
  8. Financial Information - Secure account numbers and financial data

Frequently Asked Questions

Is my data safe with this tool?

Absolutely! All encryption and decryption happens locally in your browser. No text or passwords are sent to any server. Your data never leaves your computer.

What happens if I forget the password?

Without the password, the encrypted text cannot be decrypted. This is by design for security. We don't store passwords, so there's no way to recover them.

Can I encrypt large amounts of text?

Yes, but for very large texts, performance may vary based on your device. For best results, encrypt text in reasonable chunks (under 10,000 characters).

Is this encryption really secure?

Yes! We use AES-256 encryption, which is considered unbreakable with current technology. It's the same standard used by military and financial institutions worldwide.

Can I share encrypted text with others?

Yes! You can share the encrypted text with anyone, but they'll need the exact same password you used for encryption to decrypt it successfully.

Does it work on mobile devices?

Yes! Our tool is fully responsive and works on all modern mobile devices with web browsers that support JavaScript.
