Crypto Shredder vs ShredIt

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.

ShredIt erases data by overwriting it, covering individual files and folders as well as deleted data, free space, and entire drives. It can also handle external drives, USB flash drives, and CD-RWs. Users can choose an overwrite pattern and set the number of overwrite passes; optional standards include DoD 5220, DoE, NSA, and Gutmann. Windows enables DoD 5220 Clear by default. Safety features include a pre-shred confirmation, Safe Place, and Don’t Panic for free-space erasure or disk wiping. Items can be added by dragging and dropping or choosing them from a menu, with a progress bar showing the operation. The maker offers a free trial, but trial files and folders are deleted rather than shredded. ShredIt is listed for Android, iOS, macOS, and Windows. The Windows and Mac apps each cost $24.95 as a one-time purchase. The maker’s download page lists ShredIt X v7.0.1 and ShredIt for Windows v6.0.0; Mac compatibility includes specified older releases as well as macOS 11 and 12.
