🔐 About MD5 Encryption

• Uses MD5 hash to enhance passphrase security

• Implements AES-256 encryption in CBC mode

• Generates random salt and IV for each encryption

• All processing happens locally in your browser

• No data is sent to any server

• Keep your encryption key safe - it's required for decryption

📚 Historical Context

  • MD5 was developed by Ronald Rivest in 1991
  • AES was selected as the encryption standard in 2001
  • PBKDF2 was designed to slow down brute force attacks
  • MD5 was widely used for checksums and hashing
  • AES replaced DES as the encryption standard
  • Modern browsers support Web Crypto API for secure encryption
