Uses AES-256-GCM — authenticated encryption Output format: iv:tag:ciphertext (all base64) Any key length is accepted; it's SHA-256'd to 32 bytes internally

Is the AES Encrypt / Decrypt free and private?

Yes — it runs in your browser, requires no signup for basic use, and your data never leaves your device. AES (Rijndael) was selected by NIST in 2001 after a 5-year public competition. It's approved for TOP SECRET data in US government systems.
