Tool for gf256 (Galois field) computation.

Uses Shamir's secret sharing method to allows space-effecient secret sharing (splitting) that requires a minimum threshold of shares in order to unlock the orignal secret.

Finite field GF(2^8) arithmetic with the AES reduction polynomial: multiply, inverse, exp/log tables and Reed-Solomon helpers.

Arithmetic in GF(256)

k-of-n Shamir Secret Sharing of the vault KEK for multi-party unlock. Any K of N shares recombines the key; fewer than K leaks zero bits. Composable — each share can be protected by any other on-* method. Zero runtime dependencies.
