version 0.02 - Fixed behavioural bug: wouldn't chmod directories.

Fri Jul 24 13:45:02 EEST 1998

version 0.03 - Added silent option.

Thu Aug 6 11:35:13 EEST 1998

version 0.10 - Major changes in this version

added many conditional compilation statements for

portability. now has got auxiliary random seed

sources, which can be used if a /dev/random device is

not available. now can use RC6 for generating the

cryptographically-strong random stream for

overwriting the data, as well as arcfour.

restructured source code. currently compiles under

Linux 2.0.35, SunOS 5.5.1 and AIX 4.1.

Tue Aug 11 11:01:36 EEST 1998

version 0.11 - Added compilation settings for Solaris 2.6 x86/SPARC,

FreeBSD 2.2.6-STABLE; fixed a bug in the pipe handling

in random.c (thanks to C.Mason for these).

lengthened the period of the RC6-based PRNG from

an average 2^127 to a full 2^128 (thanks to John Kelsey

<[email protected]> for explaining the period issues).

version 0.12 - Fixed a very SERIOUS bug in fill_random: the upper half of

the target buffer was NOT filled, therefore HALF OF THE

DATA was not subject to the random passes.

now wipe works on block as well as character devices.

wipe also tries to wipe file names and file sizes.

new options for letting the wiped files on the filesystem

and inhibiting file name and file size wiping.

version 0.13 - This version is SERIOUSLY BROKEN.

curiously the serious bug that should have been fixed in

version 0.12 popped up again. Thanks to Michael S. Rhee

for his diagnostic. I did some major changes in wipe's

inner workings. It now precalculates the different

fixed-pattern buffers. It is now able to do asynchronous

i/o to some extent, so that it can fill the random

buffers while the OS or the hardware is busy writing out

changes. However asynchronous i/o (i.e. the O_NONBLOCK

flag) is not supported in current Linux kernels. The way

to do it would be to use a separate thread (or a process

but that would require use shared memory). However it is

faster now.

version 0.14 - Consider version 0.13 as SERIOUSLY BROKEN. Filename

wiping has been cleaned up. Two extra options for

filename wiping have been added. Various bugs have

been fixed. This version is bug-free and 100% reliable.

Mon Jul 26 22:14:45 EEST 1999

version 0.15 - Some minor fixes. Thanks to Thomas Schoepf and Alexey

Marinichev for their bug-reports and patches: wipe was

crashing when it was operating on a single zero-length

file. Also, wipe was screwing up when attempting to

rename a file (during filename wiping). Furthermore,

wipe will no more ask for confirmation over stderr if

stderr is not a tty; it will print an error message and

exit. Use "-f" (force) option in scripts. Also improved

general behaviour and presentation. Added well-defined

return codes. Fixed a bug in length calculation. New

behaviour: wipe will now by default round up lengths to

the next multiple of file system block size so as to

wipe data possibly remaining in the last block of a

file; this behaviour can be inhibited with the new "-e"

option.

Thu Dec 30 21:50:59 CET 1999

version 0.16 - Included fix by Jason Axley for compiling under Solaris

2.6. Included patch sent by Paul H. Hargrove fixing a

serious bug (wipe-0.15 is making 34 random passes rather

than the proper mix of random and deterministic passes).

Mon Nov 25 23:13:45 CET 2002

version 0.17 - Removed somewhat useless REMOVE_ON_INT define. Cosmetic

changes. Added a -D option to make wipe follow symlinks

given on the command line. Improved wiping statistics ;

now reports number of symlinks and special files encoun-

tered separately. Updated e-mail addresses and URLs

(wow, free web hosting dies FAST !). Plus CVS, reinden-

tation and Vim modelines. I'd call this lifting. Oh,

and it now should work on devices and files greater

than 2 gigabytes. And I added some randomisation when

it tries the size of a file by resizing it.

Mon Feb 2 14:40:55 CET 2003

version 0.18 - Arf, an important bugfix was lost during the v0.17 cleanup.

When called with -r option, wipe would traverse to parent

directories ! Fixed, again (thanks to Thomas).

Sat Sep 13 14:53:11 CEST 2003

version 0.19 - wipe will hopefully work on large files now

Sat Jun 12 19:21:01 CEST 2004

version 0.20 - Thanks to Jim Paris for a patch fixing the

large file issue. Bumped up the version number a

bit.

Wed Sep 20 17:32:02 CEST 2006

version 0.21 - Included Debian patch for severe bug that affected the

computation of the size of large partitions.

Sun Nov 07 09:30:10 EST 2010

version 0.22 - Include patch by Karako Miklos to skip a number of patches.

Also did a clean up of headers (remove obsolete addresses

and CVS tags).

Tue Nov 11 08:06:35 EST 2010

version 0.23 - To conform to Gutmann's paper, randomize only

deterministic passes (as pointed out by Karako) and not

the whole order. (pointed out by K. Miklos). Fix

unreadable message displayed with the -X option.

Wed Nov 2 23:24:07 PDT 2016

version 0.24 - Integrated Debian patches from 0.22-4 per Joao

Eriberto Mota Filho's suggestion, except

50_hide-filenames.patch.
