Shamir Secret Sharing (custom impl.)

Now that there is NO doubt left about THE TOTAL ABSENCE of email privacy - a priori, I have agreed in private (face to face) communications with a few relatives that IF (only IF) we ever have to email each other about, say, sensitive stuff ... we'll use this :

All one has to pick up is one among a few well known excerpts - from novels, or poetry, or quotes, or etc - for the 254-characters long private key (first field).

It's likely not unbreakable, but not exactly trivial to defeat either. Feedback on flaws, issues, etc, otherwise much welcome of course.

(Runs entirely in your favorite browser. Can be easily adapted for the command line, too.)

"Cyril" pronounced "see real". I code stuff.
