Проблема в том что файл зашифрованный cryptmessage.txt не считывается до конца, поскольку кол-во push_back'ов при считывании message.txt countpb1 != countpb2 94!=34 из файла cryptmessage.txt Помогите срочно нужно,не бойтесь что там лютая крипта, проблема в считывании файлов, потому как ct1!=ct2 то есть ct1 = 754 ,a ct2=418 а должно быть равно одно другому потому как алгоритмы считывания одинаковы
Простой
