# How is Shamir Secret Sharing implemented within Cypherock X1

The X1 Vault implementation of SSS follows the original concepts and thus essentially is a secret sharing algorithm that operates on each byte of original data (treated as secret in the algorithm) and splits it into N number of parts of each byte.

The sharing scheme that is used in X1 Vault is (2, 5)-threshold scheme or 2-of-5 sharing scheme, wherein, any two of the cryptographic parts from the 5 generated parts can be used to retrieve the original data (or secret).
