SecureWipe vs ShredOS

SecureWipe is a free, open-source tool for erasing disks on Linux and Windows 10/11. It identifies HDD, SSD, and NVMe drives by model and serial number, and detects LUKS, BitLocker, and SED encryption. For encrypted drives it offers Crypto Erase first. Other methods include ANSSI Level 1 and 2, NIST Clear and Purge, and custom two-to-seven-pass wipes for HDDs. The tool blocks erasure of the system disk and disables NIST Purge for USB and other removable drives. Because overwriting is ineffective with SSD and NVMe wear-leveling, it blocks overwrite passes on those media and offers firmware-level or crypto erase options. After erasure, it checks a random sample, 10% by default, and produces a timestamped PDF certificate with drive details, method, verification result, watermark, and SHA-256 QR code, plus a raw text log. It has graphical and terminal modes, supports French and English with automatic locale detection, and requires Python 3.10 or later. The GUI also requires customtkinter. Its README identifies GPL v3 licensing and provides the software without warranty.

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.
