An excerpt from: http://www.tomsguide.com/us/django-long-password-security,news-17557.html

"A double-edged sword

In the case of a brute-force attack, the attacker is trying to gain access to the system. But the developer found that if the attackers are just trying to mess things up, they could go to Django's login page and repeatedly submit hundreds of extremely long "junk" passwords of thousands of characters or more.

Having to check all these junk passwords against the stored cryptographic hashes puts a heavy strain on Django's system and eventually overtaxes it.

The result is essentially a denial-of-service attack, which is when attackers bombard a server with website hits or other requests that, when combined, eventually bring the server offline.

There haven't been any known attacks that used this method. Nevertheless, Django has since patched this vulnerability by setting a limit on password length: 4096 bytes, or around 4,096 of the characters found on a keyboard. The updated version is available on Django's website. So what's the takeaway? Users should keep using long passwords. Developers, however, should be aware that strong password security could become a double-edged sword."

Going through the admin options and realized that there is not an option for a maximum password length.

I have seen, previously, this feature having its purpose questioned (https://github.com/NodeBB/NodeBB/issues/261), indicating it used to be a thing.. however it does not appear to be now. Does anybody know why?

That's a great question. i think that it depends on the nearby content. Imgur? great use; drive-by comments directly related to humor. Reddit? inferior use; substantive content is hampered by showboating at the comment level. But, at the thread level it can certainly be a useful tool; democratic nomination of the most entertaining content. And, as long as there are groups based on content those who seek something other than that can find their way home.

Just wanted to stop in here and say that this WYSIWYG composer is really very good.

Awesome. I chose Nodebb for flexibility; become the forum/CMS that I need. Nodebb never ceases to surpass expectations.

super helpful community

That is not a bad idea. My concerns lie in the creation of an account where it has you make a password.

I barely know what I am talking about, buy in theory 1 very large string could cause some performance issues on the server end. Whether that be from encrypting, storing, or pulling the password.

I have seen 14 gig notepad documents with just strings of characters for Brute forcing, so I suppose the same could be used for initiating a Denial of Service.
