下载下来是个pyc文件
使用pyc在线解密对其进行解密


写python脚本……

code = ['\x1f','\x12','\x1d','(','0',
    '4','\x01','\x06','\x14','4',
    ',','\x1b','U','?','o','6',
    '*',':','\x01','D',';','%','\x13']

for i in range(len(code)-2,-1,-1):
    code[i] = chr(ord(code[i])^ord(code[i+1]))
for i in range(len(code)):
    print(chr((ord(code[i])-i)%128),end="")

得到最终flag为GWHT{Just_Re_1s_Ha66y!}
