    AAD-50

    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. Implements a 50-cycle B→C→A phase matrix: 40 cycles NAND overwrite, 5 FTL block...

    Stegcore

    Stegcore

    A cross-platform crypto-steganography toolkit

    Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists,...

    VaultSync

    Sync directories and files in a secure folder on an external drive

    VaultSync keeps synchronised data backups from one or more computers in an encrypted vault that is locked with a password. It is optimised to operate on a flash or external drive with minimal installation but it can also work on a hosted storage system like Dropbox, One Drive or Google Drive. It is really important that a backup is simple and fast to make. There is no point in having to decide what files are important or what has changed at the time of the backup, or having to manually remove unimportant files from a deep folder hierarchy after a backup. VaultSync solves that problem. ...
