What it is

ShredOS is a small, bootable operating system for erasing disks with nwipe. The project provides .img and .iso images for USB drives, CD/DVD, Ventoy, and virtual machines. It supports x86 PCs and servers, plus Intel-based Macs, with BIOS or UEFI booting. Nwipe offers several erasure methods and pseudo-random generators, configurable rounds, verification, and a final blanking pass. ShredOS can create PDF erasure certificates and log files, with reports focused on a selected drive or the system. The image also contains utilities including smartmontools, hdparm, nvme-cli, sg3_utils, hexedit, and parallel. Documented workflows include unattended autonuke, PXE booting, persistent configuration, custom scripts, and headless operation. A user-enabled Telnet server is available in documented setups for systems with faulty or missing display hardware. Logs and PDFs can be sent to FTP or TFTP servers, though FTP does not encrypt data. The project warns that wiping is irreversible and that writing an image to a USB flash drive overwrites its existing contents. ShredOS is free and open source, with 32-bit and 64-bit builds.
