QCA - AES 128

[XerXi]

The Qt version is Qt 4.7.1 for WinCE and I've seted an environment "QTDIR" variable with its location.....
Is Qt for WinCE compatible, it isn't?

Thank you

[goetz]

I have no idea if it's supported for WinCE, maybe the maintainer(s) of QCA can help you with that.

I don't find any contact of support in QCA:http://delta.affinix.com page...

So, does anyone know if QCA:http://delta.affinix.com is compatible with Qt 4.7.1 for WinCE??

I've surfed to this page "http://delta.affinix.com/platform/":http://delta.affinix.com/platform/ and I've found another problem... Seems that QCA is available until Visual Studio 2005 and I'm developing on 2008 version.

Has anyone worked with these conditions?

Desktop Machine
Windows XP SP3
Visual Studio 2008 Professional
Qt 4.7.1 for WinCE
Add-in plugin
Intel® Core™2 Duo CPU E6550 @2.33GHz, 3,23 GB of RAM

Device Machine
Windows Mobile 6.5 Professional
Casio IT-800 —> Marvell® PXA320 624MHz

Any help?

Thanks a lot

Hello again,

I've downloaded "qca-2.0.1-mingw" and executed "installwin.bat". It seems works because in "$QTDIR\mkspecs\features" there is a "crypto.prf". Inside of this file:

@QCA_INCDIR = "D:\qt\qca-2.0.1-mingw\include\QtCrypto"
QCA_LIBDIR = "D:\qt\qca-2.0.1-mingw\lib"

prepend this file with QCA_INCDIR/QCA_LIBDIR definitions

NOTE: any changes made to this file need to be tracked in qcm/qca.qcm

CONFIG *= qt

if we are including crypto.prf from the qca tree (and not utilizing it as

an installed qmake CONFIG feature), then point to the tree. this allows our

qca tree apps to build before qca itself is installed.

exists($$PWD/qca.pro) {
QCA_INCDIR = $$PWD/include
QCA_LIBDIR = $$PWD/lib
}

LINKAGE =

on mac, if qca was built as a framework, link against it

mac: {
framework_dir = $$QCA_LIBDIR
exists($$framework_dir/qca.framework) {
#QMAKE_FRAMEWORKPATH *= $$framework_dir
LIBS += -F$$framework_dir
INCLUDEPATH += $$framework_dir/qca.framework/Headers
LINKAGE = -framework qca
}
}

else, link normally

isEmpty(LINKAGE) {
INCLUDEPATH += $$QCA_INCDIR/QtCrypto
LIBS += -L$$QCA_LIBDIR
LINKAGE = -lqca
CONFIG(debug, debug|release) {
windows:LINKAGE = -lqcad
mac:LINKAGE = -lqca_debug
}
}

LIBS += $$LINKAGE
@

The variables on top of the file are correct. Now, I don't know what is the next step. If I add to my code: @#include <QtCrypto>@ When I compile this error is printed: @fatal error C1083: Cannot open include file: 'QtCrypto': No such file or directory@

Any Idea?

Thanks!!!

Try adding this to your .pro file:

@
CONFIG += crypto
@

This adds the QCA capabilities to your project.

It doesn't work.

I'm new in Qt so I don't know if I must do something more. I only added the line what you said.

[goetz]

I don't have any further idea. QCA is not in use in my projects anymore (we once used it for the Qt3 version of our project).

Hello XerXi
Did you solved your problem ?
I've try to install QCA for Nokia QT SDK many times.
It doesn't work.
It is too difficult to install a snap-in

Hello trungnh102,

No. I used "wincrypt.h" library for c++.

Sorry

Hi,

i know that is not qt related..but can you me an example of how you use wincrypt.h for aes crypt/decrypt?
