i finally found some time to add a new "Developer's Corner" section to The OSDaB Project website with some interesting - let's hope

- tips and code snipplets. some examples:

a bunch of classes for handling of zip files (pure Qt/C++, almost written from scratch)
MD5 and SHA-1 Hashing
Base 64 encoding
XML writer
Some nice widgets (i.e. color chooser button, "rating" label and URL label)

i hope some of the stuff will be useful.
please send an email to blue_death[at]users[dot]sourceforge[dot]net for comments, corrections, suggestions and loooooooooots of money

very nice, very very nice, thx for that (code snipplets and the OSDaB Movida ) *kiss*

zip file extraction has been fixed and should now work correctly

i hope it will be usefull for someone

First Qt 4 ports uploaded

The Developer's Corner now contains some of the old code snippets ported to Qt4 (no Qt3 support library is required).

Currently available ports:

MD5 hashing algorithm
SHA1 hashing algorithm
Base64 encoding and decoding
XML Writer

I'm currently working to port Movida to Qt 4.. it will take some time though

Nice, but how about something like MD5Hash::hashArray( const QByteArray& array )? This would be very usefull for hashing passwords and authentication using challenge-response protocol.

good idea

i will add it as soon as possible to md5 and sha1 hashing classes

Hashing can also (maybe more sophisticated) be achieved through QCA http://delta.affinix.com/qca/

done

md5 and sha1 classes (both qt3 and qt4 versions) now have two methods for hashing of qbytearrays and const char* arrays.
i only uploaded files to sourceforge and updated the "download latest version" link in each webpage... i will add detail to the website as soon as possible

ps: QCA seems very interesting if you are interested in a qt wrapper for cryptographic functions... i just needed some little classes for hashing data, without the need to link some library

And it looks like it's easier to use than other cryptographic libraries. Not mentioning that it seamlessly integrates with Qt.

Exactly, you need QCA, a qca-openssl plugin and OpenSSL just to be able to use MD5 and still you must check at runtime whether all algorithms you need are available.

Zip/UnZip classes updated

new update for the developer's corner

)

the Zip and UnZip classes have been ported to Qt4, lots of baaaaad baaaad bugs have been fixed and a small command line test routine has been added to see the classes in action

please look at the website and readme file for details.. the classes have lots of limitations and surely need to be adapted to fit your needs.

quick linkz:
Qt3 Zip/Unzip
Qt4 Zip/Unzip
