FAQ

What is AES encryption?

AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely considered one of the most secure encryption algorithms, used by the US government to protect classified data.

What's the difference between GCM and CBC modes?

GCM mode provides authenticated encryption (AEAD), which verifies data integrity and prevents tampering; CBC mode only provides encryption without integrity verification. GCM mode is recommended.

What key length should I choose?

256-bit keys are recommended for highest security; 128-bit keys are also secure enough. Longer keys provide higher security with slightly slower processing.

Is my data safe?

All encryption and decryption operations are performed locally in your browser, data is never uploaded to any server. We use browser native Web Crypto API to ensure security.
