在Win平台开发Python项目往往因为加密模块不能使用crypt加密模块而感到蛋疼，这次使用Django在Win平台开发项目就又为这个加密模块而发愁。但考虑到Django有用户验证模块，证明它已具备跨平台的加密模块。于是阅读文档，在https://docs.djangoproject.com/en/1.6/topics/auth/passwords/页面发现有这样一段话
Manually managing a user’s password
The django.contrib.auth.hashers module provides a set of functions to create and validate hashed password. You can use them independently from the User model.
check_password(password, encoded)
If you’d like to manually authenticate a user by comparing a plain-text password to the hashed password in the database, use the convenience function check_password(). It takes two arguments: the plain-text password to check, and the full value of a user’s password field in the database to check against, and returns True if they match, False otherwise. Changed in Django 1.6:
In Django 1.4 and 1.5, a blank string was unintentionally considered to be an unusable password, resulting in this method returningFalse for such a password.
make_password(password[, salt, hashers])
Creates a hashed password in the format used by this application. It takes one mandatory argument: the password in plain-text. Optionally, you can provide a salt and a hashing algorithm to use, if you don’t want to use the defaults (first entry of PASSWORD_HASHERS setting). Currently supported algorithms are: 'pbkdf2_sha256', 'pbkdf2_sha1', 'bcrypt_sha256'(see Using bcrypt with Django), 'bcrypt', 'sha1', 'md5', 'unsalted_md5' (only for backward compatibility) and 'crypt' if you have the crypt library installed. If the password argument is None, an unusable password is returned (a one that will be never accepted by check_password()).
