Detailed Description

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.

KShred::KShred (  QString    fileName )

Initialize the class using the name of the file to 'shred'. Parameters: fileName  fully qualified name of the file to shred.

Member Function Documentation

bool KShred::fill0s (    )

Writes all 0's over the entire file and flushes the file buffers. Returns: true on success, false on error (invalid filename or write error)

bool KShred::fill1s (    )

Writes all 1's over the entire file and flushes the file buffers. Returns: true on success, false on error (invalid filename or write error)

bool KShred::fillbyte (  unsigned int    byte )

Writes the specified byte over the entire file and flushes the file buffers. Parameters: byte  the value to write over every byte of the file Returns: true on success, false on error (invalid filename or write error)

bool KShred::fillpattern (  unsigned char *    pattern, unsigned int    size )

Writes the specified byte array over the entire file and flushes the file buffers. Parameters: pattern  the value to write over the entire file size  the length of the 'pattern' byte array Returns: true on success, false on error (invalid filename or write error)

bool KShred::fillrandom (    )

Writes random bites over the entire file and flushes the file buffers. Returns: true on success, false on error (invalid filename or write error)

void KShred::infoMessage (  const QString &    )  [signal]

Shows a message in the progress dialog Parameters: the  message to display

void KShred::processedSize (  KIO::filesize_t    bytes )  [signal]

Shows progress of the shredding. Parameters: bytes  the number of bytes written to the file

bool KShred::shred (  QString    fileName )  [static]

The simplest method to shred a file. No need to create an instance of the class. Parameters: fileName  fully qualified name of the file to shred.

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)
