Type your secret text below, and a (5, 5)-SS (Secret Sharing) scheme will be generated. (Shares are binary, but displayed as characters.) Select different subsets of the five shares and combine them to see the result. Only when all five are combined will the secret emerge!
(It is also possible, but not implemented here, to have for example 5 shares, any 3 of which can decode the secret. Indeed, any set of subsets can be given access, with all other subsets forbidden.)
