Crypto Shredder vs D-Secure File Eraser

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.

D-Secure File Eraser overwrites file data at the sector level with the aim of making it unrecoverable. It can target files and folders, unallocated space and MFT data, cached cloud-sync copies, network shares, archives and full volumes. The product lists more than 27 sanitization algorithms, including NIST Clear/Purge, DoD, Gutmann, HMG IS5 and RCMP standards. Erasure jobs can run through CLI or REST API, webhooks, Windows Task Scheduler, cron and Group Policy hooks. Administrators can remotely execute and monitor jobs across endpoints with the Cloud Console. Each erasure produces a digitally signed PDF report containing a file hash, algorithm, pass count, operator ID and UTC timestamp; the maker also describes WORM-compliant audit logs. It says AES-256-CBC encryption is applied before overwriting, and interrupted erasures leave data cryptographically inaccessible. Windows, macOS and Linux are supported. The annual subscription starts at $40 a year, and a 30-day trial is available; there is no free plan.
