Introduction

wxChecksums is a program which calculates and verifies checksums¹. So you can check the integrity of one or more files.

wxChecksums is able to read and write files in SFV and MD5 (files generated by md5sum) format.

wxChecksums is available under Windows 9x/Me/2000/XP and Linux.

Note: In this manual some dialogs will be in french because I cannot have access to a Windows in english language. If you have Windows in english, all the dialogs should be displayed in english.

Installation

Windows

There is three ways to install wxChecksums:

With the installer. It will install all the necessary files to run the program, and will create icons in the Windows' start menu.
From a ZIP archive. This method is intended to the advanced users.
By compiling the sources. This method is intended to the programmers. The sources come with instructions to compile wxChecksums.

Note: If you are using Windows NT, Windows 2000 or Windows XP Professional, launch the installer from an administrator account if you want to create icons in the start menu for all the users of the machine. If you to wish to create icons in the start menu only for you, launch the installer from your account.

Note: A shell extension for the Windows' explorer is also available. It permits you to creates checksums' files directly from the explorer. For more information, please see the web page of wxChecksums Shell Extension for Microsoft Windows.

Linux

A RPM package is provided for Mandrake Linux 9.2. For others Linux distributions, please compile the source code with the instructions given in the COMPILE.txt file.

Using wxChecksums

Checksums' files

The checksums' files are files which contain information that check the integrity of other files. There are various methods to calculate a checksum.

wxChecksums currently manages two types of files:

SFV files. This type of file is popular under Windows and is read and generated by a lot of programs. The integrity of the files is made by the CRC-32 method.
MD5 files. This type of file is generated and read by the Unix command md5sum. The integrity of the files is made by the MD5 unidirectional hash method.

The checksums can only check the integrity of the files and cannot repair them. If you wish a tool allowing you to check the integrity of the files and to repair them, visit the site of Parchive.

The checksums' files store only information to check the integrity of the files, not the files themselves.

Relative and absolute file names

The relative file names are file names given from a reference directory. The absolute file names are file names whose path is completely defined.

Example:

my_image.png
..\my images\my_image.png
my images\my_image.png
are relative file names.
C:\My documents\My images\my_image.png
D:\Images\my_image.png
are absolute file names.

The file names are stored in the relative form in the cheksums' files. The reference directory is which where the checksums' file itself is stored.

It is strongly advised to save the checksums' file in the directory where the files to be checked are.

Management of the checksums' files

Here the main window of wxChecksums:

This window is composed of:

A menu bar:
- The File menu contains the commands to create, open, save and close checksums' files.
- The Sums menu contains the commands of management of the checksums: adding, removing and checking.
- The Settings menu permits to configure wxChecksums.
- The Help menu permits to obtain information about wxChecksums.
A tools bar.
The list of the files present in the checksums' files. This list contains:
- An icon indicating the state of the file:
  - : the file is not checked.
  - : the checksum calculated corresponds to the checksum contained in the checksums' file.
  - : the checksum calculated doesn't corresponds to the checksum contained in the checksums' file.
  - : the file couldn't be found or read.
- The name of the file.
- The directory where the file is.
- The value of the checksum contained in the checksums' file.
- Information on the state of the file.
A state bar.

Creation of a checksums' file

The creation of a file is done by the File> New... menu or by the tool.

Choose the type and the name of the new checksums' file in the following dialog:

The Browser... button allows you to choose a file name with a traditional dialog:

Opening of a checksums' file

The opening of a checksums' file can be done in two ways:

By the File > Open... menu or by the tool.
If no checksums' file is opened, by dragging a checksums' file from the explorer.

Saving the checksums' file

When a checksums' file was modified, you can save it by the File > Save menu or by the tool.

To save the checksums' file under another name, use the File > Save as... menu.

Closing of the checksums' file

Use the File > Close menu.

Adding files in the checksums' file

Adding files in the checksums' file can be done in four ways:

If a checksums' file is opened, you can drag some files and/or directories from the explorer.
By the Sums > Add files... menu or by the tool. A dialog enables you to choose one or more files to be added:
By the Sums > Add directories... menu or by the tool. A dialog box enables you to choose the directories to be added:
By the Sums > Add matching files... menu or by the tool. A dialog box enables you to enter the matching patterns to select the files to add:

The Pattern(s) field permits you to indicate which files you want to add using substitution characters. The * character replaces a sequence of characters and the character ? replaces a single character. You can specify several matching patterns by separating them by the character ;.
For example if you want to select all the bmp files which begin by Birthday, the matching pattern will be: Birthday*.bmp. If you want to select all the files with extension which finish by pp, the matching pattern will be *.?pp. If you want to select all the files with cpp and h extension, the filter will be: *.cpp;*.h.

The Directory field permits to indicate from which directory the search must begin. This directory can be absolute or relative to the directory in which the checksums' file is present. In the above screenshot, files corresponding to the matching pattern *.xpm will be searched in the directory D:\wx\src because the checksums' file in which these files will be added is D:\wx\src\images.sfv (the name of the file is indicated in the title bar of the dialog).

The Depth field indicates the recursion level with which the files will be searched from the given directory. 0 means there is no limit, 1 search only in the given directory, 2 search only in the given directory and its direct subdirectory, ...

In the above screenshot, the XPM files will be searched and added from the D:\wx\src directory, the PNG files from the D:\wx\manual directory, the JPEG files from the D:\wx directory, the GIF files from the D:\wx\src\docs\html directory (and not in its subdirectories as the depth limit was fixed at 1). Note that the JPEG files will be searched in the subdirectories of D:\wx\src\docs\html because D:\wx\src\docs\html is a subdirectory of D:\wx and there is no depth limit on the matching pattern in third position.

It is possible to save and reload the list of matching patterns using the Add list, Load list and Save list buttons. Add list loads the list of the matching patterns and adds it to the existing matching patterns, whereas Load list removes the existing matching patterns before adding the loaded matching patterns.

Note: if a file is already present in the checksums' file, it is not added.

Removing files from the checksums' file

To remove files from the checksums' file, use the Sums > Remove menu. The files are removed from the checksums' file but not from the disc.

Checking files

To check the integrity of the files, use the Sums > Check menu or the tool . If no file is selected all the files will be checked.

Recomputing the checksum of the files

To recompute the checksum of the files, use the Sums > Recompute menu or the tool . The checksums will be recomputed only for the selected files.

Check multiple checksums' files

It is possible to check simultaneously several checksums' files, by the Tools > Check multiple checksums' files....

The first dialog permits you to choose the checksums' files to check:

This dialog works like the Add matching files dialog, but the Search and add button launch immediately the file search and you can only specify absolute directory names.

Once the checksums' files to check are selected, the following progress dialog is displayed:

The displayed information can be set in the Multiple check section of the settings dialog.

Invoke wxChecksums from the command line

The general form of the command line of wxChecksums is:
wxcksums [-h] [-V] [-v] [-a str] [-c str] [-ct str] [-fl str] [--delete-temp-list] [file(s)...]

Note that the files with jokers ('*' and '?') are not treated.

Here is a table that sums up the switchs and options that wxChecksums accepts:

Long option name	Short option name	Type	Can't be used with	Can be used with	Description
--help	-h	Switch		All	Shows an help message.
--version	-V	Switch		All	Shows the version of wxChecksums.
--verify	-v	Switch	-a, -c	-ct (-ct is ignored), -fl	Verifies the given checksums' file. Only one checksums' file can be specified.
--append=<str>	-a str	Option (string)	-c, -v	-ct, -fl	Appends to the given checkums' file the given list of files. If the checksums' file doesn't exist, it is created.
--create=<str>	-c str	Option (string)	-a, -v	-ct, -fl	Creates the given checkums' file and adds to it the given list of files. If the checksums' file exists, it is overwrited (without any warning message). Prefer in general the append option.
--create-type=<str>	-ct str	Option (string)		-a, -c, -v, -fl	Specifies the type of checksums' file to create if it doesn't exist. If this option is not given, wxChecksums uses the extension of the given checksums' file: `md5` for an MD5 checksums' file; for all others extensions a SFV checksums' file is created.
--file-list=<str>	-fl str	Option (string)		-a, -c, -v, -ct	Specifies file(s) that contain a list of names of files. Theses files are text files with one name of file by line. You can specify several lists of files by separating them by the '`\|`' character.
--delete-temp-list		Switch		-fl	When specifying a list of names of files with the -fl option, deletes those which are temporary. A list of names of files is considered temporary when the extension of the file that contains the list matches one of the extensions specified by the `Files/TempExts` entry in the configuration file of wxChecksums. Default extensions are `tmp` and `temp`. See the Configuration file section for more information.

Examples:

wxcksums -a wxChecksums-x-x-x.md5 wxChecksums-x.x.x
Appends to the wxChecksums-x-x-x.md5 checksums' file the files that are in the wxChecksums-x.x.x directory. If wxChecksums-x-x-x.md5 MD5 checksums' file doesn't exist, it is created.

wxcksums -v C:\Progs\wxChecksums\wxChecksums-x-x-x.sfv
wxcksums -v wxChecksums-x-x-x.sfv
Checks the wxChecksums-x-x-x.sfv checksums' file.

wxcksums -c wxChecksums.sfv -fl "wxChecksums-1.0.0\wxChecksums-1.0.0.txt|wxChecksums-1.1.0\wxChecksums-1.1.0.tmp" --delete-temp-list -ct sfv README.txt NEWS.txt
Creates or overwrites the checksums' file wxChecksums.sfv, loads the files' names contained in wxChecksums-1.0.0\wxChecksums-1.0.0.txt and wxChecksums-1.1.0\wxChecksums-1.1.0.tmp, deletes the file wxChecksums-1.1.0\wxChecksums-1.1.0.tmp, adds to wxChecksums.sfv the files README.txt and NEWS.txt, adds to wxChecksums.sfv the files listed in wxChecksums-1.0.0\wxChecksums-1.0.0.txt and wxChecksums-1.1.0\wxChecksums-1.1.0.tmp.

wxcksums "C:\Documents and Settings\My account\My checksums file.txt"
Opens C:\Documents and Settings\My account\My checksums file.txt in wxChecksums.

Configuration

The dialog box of configuration of wxChecksums is accessible by the Settings > Configure wxChecksums... or by the tool. It is composed of six panels:

The Display panel defines all the options for the displaying of the windows and of the information provided by the list of the files.
The Behavior panel defines the behavior of wxChecksums.
The Language panel defines the language used by wxChecksums.
The Command line panel defines the behavior of wxChecksums when it is launched from the command line with certain options.
The SFV files panel defines the parameters of reading and writing of SFV files.
The MD5 files panel defines the parameters of reading and writing of MD5 files.
The Multiple check panel defines the parameters of the verification of multiple checksums' files at the same time.

This dialog is resizable and its dimensions are saved when you validate it.

Display

Save and restore the position of the window indicates to wxChecksums to save the position of the main window when exiting and to restore it on startup.
Save and restore the size of the window indicates to wxChecksums to save the size of the main window when exiting and to restore it on startup.
Headers of the checksums' list allows you to change the order of the columns of the checksums' list by selecting a column and by using the Up and Down buttons.
Save the column to sort (and the order) indicates to wxCheckums to save on which column the sorting is done and the sorting order when exiting. These parameters are always restored on startup.
Save the widths of the columns indicates to wxChecksums to save the size of the columns when exiting and to restore it on startup.
Display the directories in absolute path displays the path of the files in absolute mode rather than into relative mode. This parameter does not have an effect on the saving mode of the file names in the checksums' files.
Show checksums values in uppercase/lowercase indicates which case will be use to display the checksums' values.
Draws light horizontal (vertical) rules between rows (columns) draws light horizontal (vertical) rules between rows (columns). These options have an effect only when the application is restarted.

Behavior

Checks automatically the checksums file when opening it indicates to wxChecksums to check all the files present in the checksums' file at its opening.
Opens a dialog box to sum up the check. If this option is activated, a dialog box that sums up the checking will be opened at the end of each checking (if it was not cancelled).
Displays a warning if the state of all the files is not 'OK' when saving a checksums file. If this option is activated, when you save a checksums' file and if all the files were not checked successfully, a dialog box requires of you to confirm that you wish to save the checksums' file whereas certain files are perhaps incorrect:

Language

This tab enables you to choose the language that wxChecksums must use. The Language of the system option uses the language of the system if it is available, if not english is used by default.

Command line

These parameters defines the behavior of the GUI when wxChecksums is called with options in the command line.

Note: If you use the wxChecksums Shell Extension for Microsoft Windows, these parameters apply for it too because this extension uses the wxChecksums command line to process the action selected by the user.

If the Don't show the GUI if all the checksums are correct option is checked and if you use the --verify switch, the GUI is shown only if one or more checksums are incorrect. If all the checksums are correct and if the Opens a dialog box to sum up the check option in the Behavior page is not checked, no message is displayed to sum up the check.

The When adding files to a checksums' file and When creating a checksums' file options respectively set when to show the GUI when using the --append and --create options. An error can be for example that the checksums' file can't be saved. For the moment no warnings can occurs but future releases of wxChecksums can have it.

SFV files

The parameters presented above are the default settings. They have been defined to ensure a maximum compatibility with the other software that use SFV files.

Path separator on reading SFV files allows to force the type of path separator to use for the reading of a SFV file if the automatic recognition does not give you satisfaction.
Save the name of the generator and the date of creation in the comments adds these informations in the header of the SFV file.

Notes:

1. Checksum (from Wikipedia):
In computer technology, a checksum is a very simple integrity-protection measure. It is used mainly in data storage, and networking protocols.

It works by adding up the bytes, or some other basic components in a string of data, and storing the resulting value.

Later, anyone (who has the authentic checksum) can verify that the message was not corrupted by doing the same operation on the data, and "checking" the "sum".
