Situation réelle de la question

Comment écrire functionToGenerateMD5hash pour ce code ? J'ai déjà fileVideo et je dois envoyer le hachage md5 correspondant au serveur en cliquant sur le bouton.

$("#someButton").click(function() {
var fr = new FileReader();      
fr.onload = function(e) {            
    string md5 = functionToGenerateMD5hash(e.target.result);
    // send md5 here
};       
fr.readAsArrayBuffer(fileVideo);

En outre, pouvez-vous l'utiliser pour générer un hachage MD5 dans Node.js ?

Ajout du support Unicode à @valdeci y @Derzu versions.
Il peut également être utilisé pour md5-iser des objets JSON.
Ajout d'une incompatibilité avec IE11 et les versions inférieures :)

var md5 = (function() {
    var MD5 = function (d) {
        return M(V(Y(X(d), 8 * d.length)))
    }
    function M (d) {
        for (var _, m = '0123456789abcdef', f = '', r = 0; r < d.length; r++) {
            _ = d.charCodeAt(r)
            f += m.charAt(_ >>> 4 & 15) + m.charAt(15 & _)
        }
        return f
    }
    function X (d) {
        for (var _ = Array(d.length >> 2), m = 0; m < _.length; m++) {
            _[m] = 0
        }

Vous pouvez utiliser une bibliothèque légère pur-md5 . Juste un 4.7kb.

$("#file-dialog").change(function() {
  handleFiles(this.files);
});

function handleFiles(files) {
  for (var index = 0; index < files.length; index++) {
    var file = files[index];
    var fileReader = new FileReader();
    fileReader.onload = function(e) {
      $('body').append(`
        <div style="margin-top: 2rem;">
          <span>${file.name}: </span>
          <span>${(md5(e.target.result))}</span>
        </div>
      `);
    }

    fileReader.readAsText(file, 'utf-8');
  }

}

body {
  font-family: sans-serif;
}
