QxtBlowfish how to use?

[triperzonak]

hi im trying to use qxtcrypto to encrypt and decrypt but im having trouble using the class QxtBlowfish

in my code

#include <QxtBlowfish>
#include <QxtCrypto>
 
QByteArray var = "junk";
 
QxtBlowFish crypt;
 
crypt.setPassword(var);
 
var = crypt.encrypt(var);
 
var = crypt.decrypt(var);

#include <QxtBlowfish>
#include <QxtCrypto>

QByteArray var = "junk";

QxtBlowFish crypt;

crypt.setPassword(var);

var = crypt.encrypt(var);

var = crypt.decrypt(var);

To copy to clipboard, switch view to plain text mode 

i got undefine errors

build/dialogimpl.o(.text+0x10db):dialogimpl.cpp: undefined reference to `QxtBlowFish::QxtBlowFish(QObject*)'
build/dialogimpl.o(.text+0x1105):dialogimpl.cpp: undefined reference to `QxtBlowFish::setPassword(QByteArray)'

build/dialogimpl.o(.text+0x27ff):dialogimpl.cpp: undefined reference to `QxtBlowFish::~QxtBlowFish()'

heres my .pro

INCLUDEPATH += "C:\libqxt\include\Qxt"
LIBS += -L"C:\libqxt\lib\" -lQxtCrypto
CONFIG  += qxt
QXT     += crypto

INCLUDEPATH += "C:\libqxt\include\Qxt"
LIBS += -L"C:\libqxt\lib\" -lQxtCrypto
CONFIG  += qxt
QXT     += crypto

To copy to clipboard, switch view to plain text mode 

i did try to include the other libs but nothing happen.. what am i missing?

Could you paste the linker output? Oh, and

CONFIG  += qxt
QXT     += crypto

CONFIG  += qxt
QXT     += crypto

should be enough provided that the installation of the library succeed.

when im building it this errors show..

by the way im using windows is it necessary to install openssl?

Yes, OpenSSL is mandatory. You have to pass suitable -L, -l and -I parameters to the configure script. For example something like:

configure.bat -I C:\OpenSSL\include -L C:\OpenSSL\lib -l eay32 -l ssleay32

configure.bat -I C:\OpenSSL\include -L C:\OpenSSL\lib -l eay32 -l ssleay32

The configure script will output whether OpenSSL tests failed or passed. You can check config.log for details.

thanks.. but i got errors now.. i think my qxt0.4 is not up to date because the example functions on the net are different.

QxtBlowfish API got cleaned up quite recently. The last release differs from what's in the version control system.

[triperzonak]

where can i get the latest release bro?.. and what version of openSSL should i use?

[jpn]

You can for example download it from http://hg.libqxt.org/.
