I am a total newbie in JavaScript. I want to play with a Rest API. This requires the creation of an X-Auth key for authentication.
The documentation said:
The X-Auth-Key header should be constructed using the following algorithm: md5(api_key + md5(url + X-Auth-User + api_key + X-Auth-Expires)).
For example, consider a GET request to https://<server_ip>/api/live_events/1?clean=true by the user 'admin' with the api_key '1acpJN7oEDn3BDDYhQ' that expires on June 1, 2011 UTC. In this case the url parameter is '/live_events/1' and the X-Auth-Expires value is '1306886400'. Thus the value of X-Auth-Key should be computed as follows:
md5('1acpJN7oEDn3BDDYhQ' + md5('/live_events/1'+'admin'+'1acpJN7oEDn3BDDYhQ'+'1306886400')) => md5('1acpJN7oEDn3BDDYhQ' + md5('/live_events/1admin1acpJN7oEDn3BDDYhQ1306886400')) => '180c88df8d0d4182385f6eb7e7045a42'
I have tried to implement this with CryptoJs so far, but unfortunately I can't get the values of the example:
<script>
var md5xx = CryptoJS.MD5('/live_events/1admin1acpJN7oEDn3BDDYhQ1306886400')
var md5yy = CryptoJS.MD5(('1acpJN7oEDn3BDDYhQ') + String(md5xx));
console.log(md5yy.toString());
// => 17222238c238b7ac9f76ea8d0fe1e330
</script>
I would really appreciate some help! Thanks in advance!
The md5 hash you obtained 17222238c238b7ac9f76ea8d0fe1e330 is correct.
The given 180c88df8d0d4182385f6eb7e7045a42 example with reverse lookup gives a different link /jobs/1admin1acpJN7oEDn3BDDYhQ1306886400 instead of /live_events/1admin1acpJN7oEDn3BDDYhQ1306886400.

//the hash you actually expected

var md5yy = CryptoJS.MD5(('1acpJN7oEDn3BDDYhQ') + String(md5xx));
console.log(md5yy.toString());
//correct hash according to the given link
var md5xx = CryptoJS.MD5('/live_events/1admin1acpJN7oEDn3BDDYhQ1306886400')
var md5yy = CryptoJS.MD5(('1acpJN7oEDn3BDDYhQ') + String(md5xx));
