I would like to talk about the filesystem or whatver is relevant to this. When I delete a file, it is not actually deleted, but marked as free space, right?
So, assuming I have a program that can do these things: - issue system call to get file size in bytes - open file for writing, preserving contents - overwrite exact byte count with random junk, all 0s, all 1s, then random junk again etc etc - close file - 'delete' file (unlink system call?) and that if overwriting with sys_write() or whatever for the exact number of bytes in the file, this will only write over those blocks the file originally occupied, right? So essentially I can write a user mode file shredder/secure deletion program in C using just the standard C library on Debian?
