Data Encryptor

Encrypt and decrypt text or files using password-based AES-256 encryption with secure key derivation.

Understanding Data Encryption

Learn how our Data Encryptor protects your sensitive information using industry-standard encryption methods.

AES-256-CBC Encryption

Military-grade encryption standard

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

PBKDF2 Key Derivation

Secure password-based encryption

Password-Based Key Derivation Function 2 (PBKDF2) with 100,000 iterations and random salt. This makes brute-force attacks computationally expensive and protects against rainbow table attacks.

Client-Side Processing

Your data never leaves your browser

All encryption and decryption happens locally in your browser using the Web Crypto API. Your sensitive data and passwords are never transmitted to our servers.

Text & File Support

Encrypt any type of content

Encrypt plain text messages, documents, images, or any other file type. The encrypted output is Base64 encoded for easy sharing and storage.

Format Compatibility

Standard encryption format

Output format: salt:iv:encryptedData (all Base64 encoded). This standard format ensures compatibility and includes all necessary components for decryption.

Security Best Practices

Important security considerations

Use strong, unique passwords. Store encrypted data and passwords separately. Remember that if you lose your password, your data cannot be recovered.

Common Use Cases

Personal Data Protection

  • • Encrypt sensitive documents before cloud storage
  • • Protect personal notes and journals
  • • Secure financial records and tax documents
  • • Encrypt backup files and archives

Professional Applications

  • • Secure client data and confidential information
  • • Encrypt source code and intellectual property
  • • Protect research data and analysis
  • • Secure communication and file sharing

Important Security Reminders

  • • Choose strong passwords with a mix of letters, numbers, and symbols
  • • Never share your encryption passwords through insecure channels
  • • Keep encrypted data and passwords in separate, secure locations
  • • Test decryption immediately after encryption to verify your password
  • • Consider using a password manager for complex encryption passwords
