Usage FAQ

Usage from Address Bar

You can use direct access to this page from your browser address bar. Type string that you need to encode with algorithm according to next schema: https://md5calc.com/hash/<ALGORITHM>/<PHRASE> For example to visit page that contains hash of "hello world" you can just visit url: https://md5calc.com/hash/md5/hello+world The another cool thing is that you can specify "json" or "plain" mode into URL and you will get only HASH in response. Schema of this future: https://md5calc.com/hash/<ALGORITHM>.<OUTPUT:plain|json>/<PHRASE> Example: https://md5calc.com/hash/md5.json/hello+world Will output only: "5eb63bbbe01eeed093cb22bb8f5acdc3"

Usage from Javascript

We have removed CORS restriction so you can use direct access to hash calculator in your javascript applications via AJAX.

Example:

var toEncode = 'hello world';
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if (xhr.readyState == 4 && xhr.status == 200) {
    console.log('JSON of "'+toEncode+'" is "'+JSON.parse(xhr.response)+'"');
  };
};
xhr.open('GET', 'https://md5calc.com/hash/md5.json/'+encodeURIComponent(toEncode), true);
xhr.send();

Will output: JSON of "hello world" is "5eb63bbbe01eeed093cb22bb8f5acdc3"

Usage from PHP

You can use direct access to hash in your applications.

PHP Example: <?php
$str = 'hello world';
$url ='https://md5calc.com/hash/md5.plain/'.urlencode($str);
$md5hash = file_get_contents($url);
echo 'Hash of "'.$str.'" is "'.$md5hash.'"'; Will output: Hash of "hello world" is "5eb63bbbe01eeed093cb22bb8f5acdc3"

Keep in mind that this example no make sense because PHP has builtin function hash() which do the same.
