在这种加密下红色BASE64加密的过程是什么,如何加解密

eval(function(p,a,c,k,e,d){e=function(c){return(c<a?"":e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1;};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p;}('t p(n){f k="\\g\\r\\e\\g\\g\\g\\x\\y";f 4=[];4=n["\\e\\h\\l\\i\\2"]("");f o=v u();w(f 3=0;3<4["\\l\\1\\d\\m\\2\\9"];3++){j(k["\\b\\9\\8\\7\\a\\5\\6\\1\\c\\2"](3%k["\\l\\1\\d\\m\\2\\9"])==s){j(4[3]["\\b\\9\\8\\7\\a\\5\\6\\1\\c\\2"](0)>=I&&4[3]["\\b\\9\\8\\7\\a\\5\\6\\1\\c\\2"](0)<=H){4[3]=4[3]["\\2\\5\\G\\5\\q\\1\\7\\a\\8\\e\\1"]()}J j(4[3]["\\b\\9\\8\\7\\a\\5\\6\\1\\c\\2"](0)>=L&&4[3]["\\b\\9\\8\\7\\a\\5\\6\\1\\c\\2"](0)<=K){4[3]=4[3]["\\2\\5\\A\\h\\h\\1\\7\\a\\8\\e\\1"]()}}}z o["\\6\\1\\b\\5\\6\\1"](4["\\C\\5\\i\\d"](""))}F["\\6\\5\\b\\E\\D\\1\\d\\2"]["\\q\\7\\i\\2\\1"](p("B"));',48,48,'|x65|x74|CDXztvK5|ZNIt3|x6f|x64|x72|x61|x68|x43|x63|x41|x6e|x73|var|x31|x70|x69|if|zi2|x6c|x67|XFYJy1|ygm4|yv6|x77|x46|49|function|Base64|new|for|x3c|x2e|return|x55|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|x6a|x6d|x75|window|x4c|85|70|else|117|102'.split('|'),0,{}))
