AES Encrypt / Decrypt Tool
Encrypt and decrypt confidential data using military-grade AES-GCM (256-bit) with custom passphrases.
How to Use AES Encrypt / Decrypt Tool
Select Encrypt or Decrypt mode.
Enter plaintext/ciphertext and secure password.
Execute cryptographic encryption or decryption.
AES Encrypt / Decrypt Tool runs 100% client-side in your web browser. Your data, passwords, keys, and files are processed using the Web Crypto API and never transmitted to any server. Zero telemetry, zero storage, zero cloud processing.
Frequently Asked Questions
What makes AES-GCM secure?
