Lock a file
Pick a file and a passphrase. Paramant turns it into a locked .prmnt file that only your passphrase can open. Everything happens on this device; the file and the passphrase never leave your browser.

Your file is encrypted here, in this browser, before anything is saved. Nothing leaves your browser, so we never receive your file or your passphrase and we cannot reset it for you. Lose the passphrase and the file is gone.
