🔒 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
