    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...

    AAD-50

    Zero-trust storage erasure. Hardware-verified data destruction.

    AAD-50 is an open-source NVMe sanitization framework that closes a 15-year verification gap in Linux nvme-cli. The standard nvme sanitize command returns immediately after acceptance without confirming the drive actually completed the background erasure. AAD-50 fixes this by polling NVMe Log Page 0x81 (Sanitize Status) after every cycle and refusing to advance until SSTAT=0x1 confirms hardware completion.
