    PureBasic Shamir Secret Sharing

    PureBasic Shamir Secret Sharing

    Open-source PureBasic implementation of the Shamir Secret Sharing

    PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing...
