ssss is an implementation of Shamir's secret sharing scheme for UNIX/linux machines. It is free software, the code is licensed under the GNU GPL v2. ssss does both: the generation of shares for a known secret and the reconstruction of a secret using user provided shares.
Shattr is a website where you can split your secrets into several shards such that if a certain number of them are combined, the secret can be recovered, but otherwise, no information about the secret can be obtained.
