Encryptor

100% local v1.1.4

Lock text or files behind a passphrase with AES-256-GCM. Keys are derived in your browser with PBKDF2 — nothing is ever uploaded, and only the passphrase can unlock it.

Encryption needs a secure context. Open this tool over https or on localhost and reload.

PBKDF2 iterations

More iterations slow down brute-force attacks but take longer to derive the key. The choice is stored inside the container, so decryption always uses the right value.

About this tool

Lock any text or file behind a passphrase using AES-256-GCM. The key is derived in your browser with PBKDF2 (tunable iterations) and the output is a self-describing container you can decrypt on any device. Nothing leaves the browser — no upload, no accounts, no keys stored anywhere.
