Je n'arrive pas à wrapper la classe blowfish

Bonjour,

J'ai récupéré sur le net une classe blowfish permetant d'utiliser l'algorythme du même nom. Cependant je souhaite modifier ces dernières afin de les adapters à mes besoin. Le code étant en LGPL j'ai donc décidé de faire un wrapper.

Malheuresement je rencontre un gros soucis, j'ai créer une instance de blowfish dans ma classe blowFishWrapper, dans le constructeur je lance l'initialisation de la clé. Ensuite peut importe l'action lancé sa crash. Pour moi l'erreur ce trouve au niveau du constructeur, cependant sans message pour le confirmer je doit avouer que je patauge un peux ...

	blowFishWrapper();
	virtual ~blowFishWrapper();

	blowFish.Initialize(key, 4);

Si quelqu'un voit ou ce trouve mon erreur ... Merci d'avance :ccool:

Ton problème ne se situe pas au niveau du constructeur. Il faut que tu regardes du coté de ta méthode blowFishWrapper::encode ....

C'est ta transformation avec atoi qui plante...
J'ai juste vu cela en copiant/collant ton code.

Mais pour la prochaine fois, mets au moins soit des print si t'es sous linux, soit des breakpoints si t'es sous Visual....
Ca permettra de cibler plus rapidement l'erreur

Je les avais volontairement supprimé afin de minimiser le code, erreur de ma part désolé x)

Effectivement la transformation peut être mise en cause pour une erreur, cependant il y en a forcement une autre. J'ai ajouter une autre méthode :
Code:

1 2 3 4 5 6 7 unsigned char* blowFishWrapper::test(unsigned char* input){ unsigned char* output; std::cout << "3" << std::endl; blowFish.Encode(input, output, 6); std::cout << "4" << std::endl; return output; }
Le dernier cout affiche 3. Je me suis dit qu'un problème survenait peut-être à l'appelle de la méthode, je l'ai donc écrite différemment :
Code:

1 2 3 4 5 6 7 8 9 unsigned char* blowFishWrapper::test(unsigned char* input){ unsigned char* a = (unsigned char*)"coucou"; unsigned char* b; std::cout << "3" << std::endl; blowFish.Encode(a, b, 6); std::cout << "4" << std::endl; std::cout << a << std::endl; std::cout << b << std::endl; }
Encore une fois la même erreur survient. Par contre celui-ci fonctionne :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 unsigned char* blowFishWrapper::test(unsigned char* input){ CBlowFish blowFish2; unsigned char* key = (unsigned char*)"dell"; blowFish2.Initialize(key, 4); unsigned char* a = (unsigned char*)"coucou"; unsigned char* b; std::cout << "3" << std::endl; blowFish2.Encode(a, b, 6); std::cout << "4" << std::endl; std::cout << a << std::endl; std::cout << b << std::endl; }
Je pense donc que c'est un problème du à l'instance blowfish. Malheureusement je ne voit pas comment régler ce problème ...

Salut,

Code:

1 2 3 4 5 6 7 unsigned char* blowFishWrapper::test(unsigned char* input){ unsigned char* output; std::cout << "3" << std::endl; blowFish.Encode(input, output, 6); std::cout << "4" << std::endl; return output; }
output n'est pas initialisée et à fortiori ne pointe pas sur une zone valide. Conclusion : l'écriture a lieu dans un endroit indéterminé provoquant erreurs et plantages au petit bonheur.

Bonjour,

Y a t'il une différence d'initialisation entre un main et une méthode ?
Je demande ça car la méthode est en fait un copier coller d'un code que j'ai réaliser dans mon main et qui fonctionne parfaitement :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 unsigned char* input = (unsigned char*)"coucou"; unsigned char* output; CBlowFish blowFish; unsigned char* key = (unsigned char*)"dell"; blowFish.Initialize(key, 4); blowFish.Encode(input, output, 6); cout << input << endl; cout << output << endl; unsigned char* output2; blowFish.Decode(output, output2, strlen((const char*)output)); cout << output << endl; cout << output2 << endl; exit(0);

Après quelques tests... j'ai peut-être une piste...
En faisant quelques tests, j'ai pu constaté que ta variable b dans ta première fonction test (celle qui ne marche pas) n'est pas initialisée.

Perso je l'ai écrite comme cela :
Code:

1 2 3 4 5 6 7 8 9 10 unsigned char* blowFishWrapper::test(){ unsigned char* a = (unsigned char*)"coucou"; unsigned char b[30]; std::cout << "3" << std::endl; blowFish.Encode(a, b, 6); std::cout << "4" << std::endl; std::cout << a << std::endl; std::cout << b << std::endl; return b; }
En fait pour moi, je confirme que ce n'est pas au niveau du constructeur qu'est le problème. Le programme passe bien dedans, les variables sont bien initialisées.

Essayes avec ca.

Oo
Effectivement sa marche du tonnerre !

Merci à vous deux, c'est donc effectivement un problème d'initialisation de variable ...
Du coup j'en déduis que l'initialisation dans le main et dans une méthode sont traité différemment.

Tant de temps perdu sur une erreur aussi bête ...
Merci beaucoup :zoubi::zoubi::zoubi:

Tu as juste de la chance car il n'y a aucune raison pour que ce code marche mieux que l'autre. Le fait d'écrire dans une zone indéterminée provoque un comportement ... indéterminé. Ce qui veut dire que parfois ça peut 'tomber en marche' et dans le meilleur des cas, planter.

Il faut réserver l'espace nécessaire à ta sortie.

Vu le temps que j'ai perdu je pense que je ne referais plus cet erreur, en tout cas j’espère :aie:
