Summary: Shamir's Secret Sharing Scheme

Description:
ssss is an implementation of Shamir's secret sharing scheme for UNIX/linux machines. Citing from the Wikipedia article about Secret Sharing: In cryptography, a secret sharing scheme is a method for distributing a secret amongst a group of participants, each of which is allocated a share of the secret. The secret can only be reconstructed when the shares are combined together; individual shares are of no use on their own. More formally, in a secret sharing scheme there is one dealer and n players. The dealer gives a secret to the players, but only when specific conditions are fulfilled. The dealer accomplishes this by giving each player a share in such a way that any group of t (for threshold) or more players can together reconstruct the secret but no group of less than t players can. Such a system is called a (t,n)-threshold scheme. ssss does both: the generation of shares for a known secret and the reconstruction of a secret using user provided shares.
