No data sent to servers
Strong password hashing
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.
Text encryption converts readable plain text into unreadable ciphertext using cryptographic algorithms. Here's how our tool works:
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.
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.
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.
The encrypted output is encoded in base64 format, making it safe to copy, paste, and share across different platforms without corruption.
Our tool implements multiple security layers to ensure your data remains protected:
Follow these guidelines to maximize the security of your encrypted text:
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.
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.
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).
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.
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.
Yes! Our tool is fully responsive and works on all modern mobile devices with web browsers that support JavaScript.
