Crypto Shredder
Crypto Shredder is Windows software that overwrites accessible file and directory data before deleting it.
What Crypto Shredder is
Crypto Shredder is Windows software that overwrites accessible file and directory data before deleting it. It replaces file contents with cryptographically generated random data, then flushes and synchronizes the write. Its AES-256-GCM process runs three times on an in-memory copy, with a new 256-bit key and nonce for each pass; the encrypted output is not saved as a file. Before releasing its final working buffer, the application writes zeros over it, though Python and the operating system may manage other temporary memory. It asks users to confirm before processing and can export an optional text report recording the date and time, computer, Windows user, IP address, selected item, and processing sequence. The maker describes it as a standalone app requiring no installation. Crypto Shredder is free, and its listed Windows edition is free. It handles files and folders, not drive wiping. The maker cautions that overwriting cannot guarantee sanitization of every physical NAND cell on SSD or NVMe storage, or remove copies outside the app’s control.
Good
- Overwrites accessible file and directory data before deletion.
- Uses three AES-256-GCM passes with new keys and nonces.
- Optional text reports record processing details.
- Standalone app requires no installation.
- Free Windows edition costs nothing.
Watch out
- Does not wipe drives.
- Cannot guarantee sanitization of every SSD or NVMe NAND cell.
- Copies in backups and other locations remain outside its control.
- Deletion is permanent and cannot be undone by the application.
Who it suits
It may suit Windows users, including IT, security, and compliance teams, businesses, and everyday users who need to delete files or folders. It is not for users seeking whole-drive wiping.
Verdict
Crypto Shredder provides a free way to overwrite accessible file and folder data before deletion, with optional activity reports. Its limits matter: it does not wipe drives, cannot guarantee physical SSD or NVMe sanitization, and cannot address copies beyond its control.
