Wie erstelle ich einen MD5-Hash aus einem String in Code::Blocks (MinGW) (GELÖST)
-
Hallo Leute,
*also ich bin überhaupt noch kein guter Coder. Ich hab gerade mal nen Trainer für nen Spiel erstellt was ja nicht wirklich schwer ist.
Jetzt habe ich wirklich über knapp 12 Stunden so ziemlich alle MD5 Beispiele die im Internet zu finden sind, versucht mit meiner IDE zu kompilieren, ohne Erfolg. Ich bin total am Ende!*
Kann mir vielleicht jemand ein simples Beispiel zeigen, wie ich mit einer Konsolenapplikation einen MD5 Hash aus einem String erzeugen kann und das jenes mit Code::Blocks (Wie Dev-C++ -> MinGW) fehlerfrei funktioniert?
Gruss

Wenns viel arbeit macht
Ich bin bereit auch 50 Euro (PSC/Überweisung) für etwas funktionierendes zu bezahlen.

MD5String muss auf jeden fall raus. ändere den kopf von MD5Init von...
void MD5Init (mdContext) MD5_CTX *mdContext;in das...
void MD5Init (MD5_CTX *mdContext)^^schon müssten ein paar fehlerchen weg sein.

kein problem, weiter geht's. such die zeilen:
/* forward declaration */ void Transform ();und ändere sie in:
/* forward declaration */ void Transform (UINT4 *buf, UINT4 *in);

Du bist n feiner kerl,
danke das du dir so viel mühe gibst.
also ich hab jetzt
static void Transform ();in
static void Transform (UINT4 *buf, UINT4 *in);geändert.
jetzt kommt folgender Fehler:

nun, dann gehen wir mal in die 'main'-funktion und machen aus der zeile:MD5Update (&ctx, in, (unsigned int)strlen(in));das...
MD5Update (&ctx, (unsigned char*)in, (unsigned int)strlen(in));

ahaa jaaa!
endlich nach einer million versuche!
ES FUNKTIONIERT!
DANKE ;fricky!!!
wieso das aber auch immer so kompliziert sein muss
hätte ich mit VC++ da keine probleme gehabt?
gruss

PS: an welche org soll ich das geld nun schicken?

doch, auch. das ++ suckt rum, ohne hätte es gleich beim ersten oder zweiten versuch geklappt.

irgendwas humanitäres o.ä, amnesty international, kinderhilfswerk, greenpeace oder so, such dir was aus. und wehe dir, die kohle geht bei denen nicht ein. ich rufe da an *fg*

ja danke wirklich.
ich werd das machen, im ernst.
ich sag dir dann bescheid wohin es ging
PS: kannst du mir noch schnell sagen wie ich den md5hash in ne variable packen kann?
(prinzipiell wollte ich das ja damit ich md5 hash in meiner applikation vergleichen kann)

das ergebnis ist in MD5_CTX.digest[], 16 unsigned char's (siehste z.b. an der ausgabe in 'main'). kannst es z.b. mit 'memcpy' o,ä. irgendwo hinkopieren. ansonsten arbeite mal ein C-tutorial durch, damit du überhaupt weisst, was du da machst.

hehe
ja ich weiss schon was ich da mach
sagen wir so ich kann die sprache besser lesen als schreiben
sowas hab ich noch nie gemacht
danke für die anhaltspunkte.
ich werds sicher rauskriegen.
