BUUCTF-pyre

下载附件是一个.pyc文件，在pyc在线反编译工具里反编译一下，代码如下: ` print "Welcome to Re World!"print "Your input1 is your flag~"l = len(input1)for i in range(l):　　num = ((input1[i] + i) % 128 + 128) % 128　　code += numfor i in range(l - 1):　　code[i] = code

[GWCTF 2019]pyre 1

py文件,随便在网上搜个反编译器,看看源码 看下就是很简单的俩轮加密,反着写过去就行了. 贴上别人的脚本… print(‘Welcome to Re World!’) print(‘Your input1 is your flag~’) code = [0x1f,0x12,0x1d, 0x28,0x30,0x34, 0x01,0x06,0x14, 0x34, 0x2c, 0x1b, 0x55,0x3f,0

初步探索 .pyc文件 通过在线 反编译后 print 'Welcome to Re World!' print 'Your input1 is your flag~' l = len(input1) for i in range(l): num = ((input1[i] + i) % 128 + 128) % 128 code += num for i in range(l - 1): code[i] = code[i] ^ code

pyc反编译之后 print 'Welcome to Re World!' print 'Your input1 is your flag~' l = len(input1) for i in range(l): num = ((input1[i] + i) % 128 + 128) % 128 code += num for i in range(l - 1): code[i] = code[i] ^ code[i + 1] prin
