I am making another website and I want to use the Xenforo cookie for logins. I noticed there is a cookie like this which has the userid, %2C, and a 40 character hex string. xf_user=1%2Ce7b78a045bbb24543745092b09aaa3ea9e2ecbad How do I use this hash to verify the cookie was not tampered with? Or is there a better way to get the current user without loading the xenforo library in php? Update Never mind I just decided to use the session cookie.
