AES-256-GCM Authenticated Cipher

Uses authenticated Galois/Counter Mode with 256-bit encryption keys derived via PBKDF2 with 100,000 iterations and random 16-byte salt + 12-byte IV.

Zero-Trace Client-Side Privacy

All cryptographic operations execute strictly inside browser memory using the Web Crypto API. Neither plaintext nor passwords ever leave your machine.

Air-Gapped QR Transfer

Instantly generate camera-scannable QR codes for encrypted payloads to securely transfer credentials between air-gapped devices.

Frequently Asked Questions

Which encryption algorithm does this tool use?
We use authenticated AES-256-GCM encryption with 256-bit keys derived using PBKDF2 with 100,000 iterations via the native Web Crypto API.
Can AgentXAlpha decrypt my encrypted messages or view my passwords?
No. All encryption and decryption operations happen strictly in your browser memory. We have zero access to your plaintext, passwords, or ciphertext.
Can I decrypt text on a different computer or device?
Yes, as long as you have the exact ciphertext payload and the correct encryption password/passphrase.
Why is AES-GCM preferred over older cipher modes like CBC?
AES-GCM provides authenticated encryption with associated data (AEAD), which guarantees both confidentiality and data integrity, protecting against tampering and padding oracle attacks.
