请问您可以重新格式化您的问题？使用101010按钮标记代码块，以全英文说话，不要使所有内容都大胆。 – 2010-11-15 09:35:34

haslib.new()期望哈希算法名称（例如“md5”，“sha1”等）作为第一个参数。你正在传递一个随机字符串。

它看起来像你试图用它来实现你自己的注册框架。现有的有什么问题？我认为你应该通常阅读更多关于Django框架的知识，并阅读教程。

看着这个回溯，问题是在hashlib.new(str(random.random())).hexdigest()[:5]行。（熟悉看着回溯和工作出来的问题是什么，你会发现你需要经常，当你犯了一个错误。）

help(hashlib.new)表明这一点：

__hash_new(name, string='') 
    new(name, string='') - Return a new hashing object using the named algorithm; 
    optionally initialized with a string.

的“命名的算法”应该是MD5，SHA1，SHA256等（用于列表，请参阅help(hashlib)，以及如何你应该使用如hashlib.md5()代替hashlib.new('md5')）

当密码是在节省时间hashlib，而不是我用SH一个加密算法工作正常
