What is this code at the bottom of the landing page?

Question

PHP

/* <![CDATA[ */(function(d,s,a,i,j,r,l,m,t){try{l=d.getElementsByTagName('a');t=d.createElement('textarea');for(i=0;l.length-i;i++){try{a=l[i].href;s=a.indexOf('/cdn-cgi/l/email-protection');m=a.length;if(a&&s>-1&&m>28){j=28+s;s='';if(j<m){r='0x'+a.substr(j,2)|0;for(j+=2;j<m&&a.charAt(j)!='X';j+=2)s+='%'+('0'+('0x'+a.substr(j,2)^r).toString(16)).slice(-2);j++;s=decodeURIComponent(s)+a.substr(j,m-j)}t.innerHTML=s.replace(/</g,'&lt;').replace(/>/g,'&gt;');l[i].href='mailto:'+t.value}}catch(e){}}}catch(e){}})(document);/* ]]> */

this code to protect soap parsing? how to know if it works? and where does it come from?

Answer 1

cloudflare? I saw something like that with them. There is nothing wrong here, just a function that replaces "<", ">" with codes. Does a good job as I understand it.
