可以看到压缩并编码的内容。
这段内容是插入到文件里的，但是偶尔（就是没有成功重现过，大概是在用户第一次使用软件的时候，我的电脑从来没有出现过）会在中间插入一段文字
"Administrator" Sid: S-1-5-21-1987871192-1803184254-2498118558-500
最后有个换行。
变成这样：
....XMkMfUQip2COqEJ"Administrator" Sid: S-1-5-21-1987871192-1803184254-2498118558-500
e4arFR1FNLwA0Tk/ZBgmAWzrQvbe89WVKGY/vUi5....
我认为这个问题是出在 b64encode 环节的。
google python sid b64encode 找不到任何思路。
我的思路是不是错了？

检查你的代码有没有多线程写文件，或者文件名冲突的情况，
其次检查出问题的电脑上有没有什么卫士，助手，管家之类的， 如果在干净的系统环境下也会出问题， 100%是你代码的问题 |

base64, zlib 怎么可能会去拿你的系统的 SID= =
很明显是你给它的内容就多了一行 为什么会认为是编码有问题呢= = |

Weakdancer OP @hahastudio 我也认为 base64 不会取 Sid ，但是怎么解释 sid 出现在 base64 编码的中间呢？
把 sid 去掉之后还是能够重新解码的。 这个代码不是我写的。是开源的 3d 打印切片软件。 https://github.com/daid/Cura/blob/SteamEngine/Cura/util/profile.py#L863 |
