【解法】

觀察發(fā)現最大的為f，猜測可能為16進制薄扁，16進制轉為字符串得到：

????????Kecog, K ucy, K eqpswgtgf.

????????Eqyctfufkg ocp{ vkogu dghqtg vjgkt fgcvju,vjg xcnkcpv pgxgt vcuvg qh fgcvj dwv qpeg.

????????Uckfd{ Lwnkwu Ecguct, Tqocp Ngcfgt

????????hnci{e2o5_ucy_Lq3p_63f_E2psw5tg_evh!}

發(fā)現h n c i 分別與f l a g相差2剪返，可能為凱撒密碼，密鑰為2邓梅，得到：

????????I came, I saw, I conquered.

????????Cowardsdie man{ times before their deaths,the valiant never taste of death but once.

????????Saidb{ Julius Caesar, Roman Leader

????????Justlike what Caesar said, {ou conquered, {ou deserve it.

????????flag{c2m5_saw_Jo3n_63d_C2nqu5re_ctf!}

由于數字也要向前移動2位脱盲，則為flag{c0m3_saw_Jo1n_41d_C0nqu3re_ctf!}
