AES Encryptor/Decryptor

Secure AES-GCM symmetric encryption

Security: Encryption is performed locally in your browser. Your data and keys are never sent over the Internet. Keep your keys safe — without the key, encrypted data cannot be recovered.

About AES-GCM
AES (Advanced Encryption Standard):
  • Standard symmetric encryption algorithm
  • Used by governments and enterprises worldwide
  • Considered unbreakable with a 256-bit key
Mode GCM (Galois/Counter Mode):
  • Provides both confidentiality and authentication
  • Detects any modification of encrypted data
  • Recommended for most modern applications

Encryption components:
  • Key: Shared secret used to encrypt/decrypt (128, 192 or 256 bits)
  • IV: Random initialization vector (96 bits for GCM)
  • Auth Tag: Authentication tag ensuring data integrity (128 bits)
  • PBKDF2: Password-based key derivation function (100,000 iterations)
