Disclaimer

This service is a demo, and is NOT SECURE in any sense of the word. It was lazily whipped together in a few hours as a fun proof of concept. Both your secret message and the extraction password will be sent in cleartext to the server. They can be intercepted by any eavesdropper along the way, and might remain cached on the server indefinitely. DO NOT USE THIS SERVICE FOR ANYTHING YOU ACTUALLY WANT TO HIDE OR PROTECT.
