simple text encryption program with Qt GUI
N-Crypter is simple standalone Text encryption/decryption tool wriiten in GCC C++
note :this is a simple encrypter anyone with source code could simply decrypt it !
this is a fun project , sorry for bugs
g++ & Qt v.5
this program simply change every text to its ASCII value and change that ASCII value and reconverting to Text
QString ncrypter::encrypt(QString text){
for(int i=0 ; i<text.size() ; ++i){
int key = i%4;
QChar tempchar = QChar(text[i]);
int num = tempchar.toLatin1();
switch(key){
case 0 : num ++;
break;
case 1 : num += 2;
break;
case 2 : num += 3;
break;
case 3 : num += 4;
break;
}
char newchar = num;
text[i] = newchar;
}
return text;
}
the decryption is also work in almost same way the only change is while encryption convert the charecter to next ones decrytion converts it to previous one
