What do you have?

One .cqen file — a single encrypted image, or an encrypted zip of many images (from "Zip → Encrypt"). Upload it directly below; we detect which it is after decrypting.

One .zip file — containing multiple .cqen files (from "Encrypt → Zip"). Upload it below; we unzip it first, then ask for your password.

Not sure? Just upload whatever single file you were given — we'll figure out the rest.
