Detailed Description

Deprecated:

Erase a file in a way that makes recovery impossible -- well, no guarentee of that, but at least as difficult as reasonably possible. For this, KShred write several times over the existing file, using different patterns, before deleting it.

No need to create an instance of the class.

Parameters:

fileName

fully qualified name of the file to shred.

Definition at line 149 of file kshred.cpp.

bool KShred::shred

(

)

Shreds a file by writing a series of values over it (uses fill0s, then fill1s, then fillrandom, then fillbyte with 0101.

.., then fillbyte with 1010....

Returns:

true on success, false on error (invalid filename or write error)
