About AES Encryption

This tool uses AES-256-GCM (Galois/Counter Mode) with PBKDF2 key derivation to encrypt your data. The encryption is performed entirely in your browser using the Web Crypto API - no data is ever sent to any server.

  • AES-256 provides military-grade encryption with 256-bit keys
  • GCM mode provides authenticated encryption (integrity protection)
  • PBKDF2 with 100,000 iterations protects against brute-force attacks
  • Random salt and IV ensure unique ciphertext even for same plaintext
  • Use the AES Decrypt tool with the same passphrase to decrypt
