🔒 AES Encryption

Encrypt and decrypt text using AES-GCM (Advanced Encryption Standard - Galois/Counter Mode)

About AES-GCM Encryption:

  • Algorithm: AES-GCM provides both encryption and authentication
  • Key Size: 128-bit or 256-bit keys (256-bit recommended for higher security)
  • IV (Initialization Vector): Randomly generated for each encryption, included in output
  • Format: Output format is iv:ciphertext (both in hex)
  • Security: Keep your encryption key secret and secure
  • Use Cases: Secure data storage, message encryption, file encryption

⚠️ Important Security Notes:

  • Never reuse the same IV (Initialization Vector) with the same key
  • Store your encryption key securely - if lost, data cannot be recovered
  • For production use, consider using a key management system
  • This is for educational/testing purposes only
