3. 基本流程： 4. 注册机#!python3import hashliboutput = []str = input()hash = 1()(('utf-8'))hash = est()xor_str_1 = [0x50,0x45, 0x44, 0x49, 0x59, 0x20, 0x46, 0x6F ,0x72 ,0x75, 0x6D, 0x00 ]xor_str_2 = ""num = 0# print(hash)for i in range(0,34,2):if i > 22: b = '0x' + (hash[i] + hash [i+1]) a = eval(b) ^ eval(output[int((i/2))-12]) (hex(a))continue b = '0x' + (hash[i] + hash [i+1]) a = eval(b) ^ (xor_str_1[int(i/2)]) (hex(a))for i in range(34,40,2): b = '0x' + (hash[i] + hash [i+1]) a = eval(b) ^ ord(xor_str_2[int(i/2)-17]) (hex(a))for i in range(10): output[10+i] = hex(eval(output[i]) ^ eval(output[10+i]))for i in range(10,20):print('{:0>2}'.format((output[i][2:]).upper()),end = "")成功！ 5. 计算函数的部分伪代码参考。
