Crypto Shredder vs Raider

Crypto Shredder is Windows software for overwriting accessible file and directory data before deleting it. It replaces file contents with cryptographically generated random data, then flushes and synchronizes the write. It also processes an in-memory copy three times with AES-256-GCM, using a new 256-bit key and nonce on each pass; encrypted output is not saved as a file. Before releasing its final working buffer, the application overwrites it with zeros, while noting that Python and Windows may manage other temporary memory. Users confirm before processing and can optionally export a text report with the date and time, computer, Windows user, IP address, selected item, and processing sequence. The maker describes it as a standalone app that requires no installation. Crypto Shredder handles files and folders, not drive wiping. Its maker cautions that overwriting cannot ensure every physical NAND cell on SSD or NVMe storage is sanitized, or remove copies beyond the app’s control. The free Windows edition costs nothing.

Raider, listed as File Shredder on its GNOME app page, is a free Linux app for making recovery of deleted sensitive files more difficult. It is designed to permanently remove files from a computer and supports folder shredding with custom shredding standards. It does not offer free-space shredding or scheduled shredding. The app cautions that modern SSD technology prevents shredding from being perfect, although it can raise the difficulty of data recovery. The GNOME app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. Version 3.1.0 is the listed latest release, dated May 18, 2025. Its changes include a GNOME 48 update, a modernized circular progress indicator, fixes for small memory leaks, and DBus launch support.
