AES Encryption Guide

AES-GCM (Advanced Encryption Standard - Galois/Counter Mode) is an authenticated encryption algorithm that provides both confidentiality and integrity. The password is derived into an encryption key using PBKDF2 with 100,000 iterations and a random salt, making it resistant to brute-force attacks.

What encryption is used?

This tool uses AES-256-GCM with PBKDF2 key derivation (100,000 iterations). The salt and IV are randomly generated and included in the output.

Is it safe to use?

Yes. All encryption/decryption happens in your browser using the Web Crypto API. No data leaves your device.

Can I decrypt elsewhere?

The output format is salt(16)+iv(12)+ciphertext encoded as Base64. You can implement the same scheme in any language with a crypto library.

Is this tool free?

Yes, completely free with no signup or limits.
