Django设置“ SECRET_KEY”的目的 [英] Purpose of Django setting ‘SECRET_KEY’

问题描述

SECRET_KEY 在django中的确切含义是什么？我做了一些Google搜索，并检查了文档（ https：// docs.djangoproject.com/en/dev/ref/settings/#secret-key ），但我一直在寻找对此问题的更深入说明以及为什么需要这样做。

What exactly is the point of the SECRET_KEY in django? I did a few google searches and checked out the docs ( https://docs.djangoproject.com/en/dev/ref/settings/#secret-key ), but I was looking for a more in-depth explanation of this, and why it is required.

例如，如果密钥被盗/其他人知道密钥是怎么回事？谢谢。

For example, what could happen if the key was compromised / others knew what it was? Thank you.

它用于创建哈希。外观：

It is used for making hashes. Look:

>grep -Inr SECRET_KEY *
conf/global_settings.py:255:SECRET_KEY = ''
conf/project_template/settings.py:61:SECRET_KEY = ''
contrib/auth/tokens.py:54:        hash = sha_constructor(settings.SECRET_KEY + unicode(user.id) +
contrib/comments/forms.py:86:        info = (content_type, object_pk, timestamp, settings.SECRET_KEY)
contrib/formtools/utils.py:15:    order, pickles the result with the SECRET_KEY setting, then takes an md5
contrib/formtools/utils.py:32:    data.append(settings.SECRET_KEY)
contrib/messages/storage/cookie.py:112:        SECRET_KEY, modified to make it unique for the present purpose.
contrib/messages/storage/cookie.py:114:        key = 'django.contrib.messages' + settings.SECRET_KEY
contrib/sessions/backends/base.py:89:        pickled_md5 = md5_constructor(pickled + settings.SECRET_KEY).hexdigest()
contrib/sessions/backends/base.py:95:        if md5_constructor(pickled + settings.SECRET_KEY).hexdigest() != tamper_check:
contrib/sessions/backends/base.py:134:        # Use settings.SECRET_KEY as added salt.
contrib/sessions/backends/base.py:143:                       settings.SECRET_KEY)).hexdigest()
contrib/sessions/models.py:16:        pickled_md5 = md5_constructor(pickled + settings.SECRET_KEY).hexdigest()
contrib/sessions/models.py:59:        if md5_constructor(pickled + settings.SECRET_KEY).hexdigest() != tamper_check:
core/management/commands/startproject.py:32:        # Create a random SECRET_KEY hash, and put it in the main settings.
core/management/commands/startproject.py:37:        settings_contents = re.sub(r"(?<=SECRET_KEY = ')'", secret_key + "'", settings_contents)
middleware/csrf.py:38:                % (randrange(0, _MAX_CSRF_KEY), settings.SECRET_KEY)).hexdigest()
middleware/csrf.py:41:    return md5_constructor(settings.SECRET_KEY + session_id).hexdigest()
