  • Django自带加密模块的使用

    django官网介绍:https://docs.djangoproject.com/en/2.1/topics/auth/passwords/#module-django.contrib.auth.hashers

    Manually managing a user’s password¶
    The django.contrib.auth.hashers module provides a set of functions to create and validate hashed passwords. You can use them independently from the User model.
    
    check_password(password, encoded)[source]¶
    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.
    
    make_password(password, salt=None, hasher='default')[source]¶
    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). See Included hashers for the algorithm name of each hasher. If the password argument is None, an unusable password is returned (one that will never be accepted by check_password()).
    
    is_password_usable(encoded_password)[source]¶
    Returns False if the password is a result of User.set_unusable_password().
    
    Changed in Django 2.1:
    In older versions, this also returns False if the password is None or an empty string, or if the password uses a hasher that’s not in the PASSWORD_HASHERS setting. That behavior is considered a bug as it prevents users with such passwords from requesting a password reset.

    通过django自带的类库,来加密解密很方便,下面来简单介绍下;

    在settings.py里添加:

    PASSWORD_HASHERS = [
        'django.contrib.auth.hashers.PBKDF2PasswordHasher',
        'accounts.hashers.PBKDF2WrappedSHA1PasswordHasher',
    ]

    导入包:

    from django.contrib.auth.hashers import make_password, check_password

    加密:

    make_password(password, salt=None, hasher='default')

    See Included hashers for the algorithm name of each hasher.
    If the password argument is None, an unusable password is returned (one that will never be accepted by check_password()).

    验证:

    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.

    注:

      

    hasher可取以下值:
    
        pbkdf2_sha256
        pbkdf2_sha1
        argon2
        bcrypt_sha256
        bcrypt
        sha1
        md5
        unsalted_sha1
        unsalted_md5
        crypt
