Open Source Linux File Shredders

This application wipes your storage units (HDDs, SSDs, and flash drives) and renders them unrecoverable. This process is irreversible, and the data cannot be recovered later. Using this application is especially recommended if you're considering selling your storage units. The program is powered by the default kernel module, the "shred" tool. It's bilingual (English and Turkish) and easy to use. Simply select your drive and click the "Destroy!" button. https://github.com/shampuan/Linux-Disk-Destroyer

LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. See the project homepage https://libsecrm.sourceforge.io and the project Wiki in the menu above. To wipe data that was left on the drive by using "normal" delete operations, you can take a look at WipeFreeSpace (https://wipefreespace.sourceforge.io), which wipes the space used by files marked as deleted (and other things, too).
