 window.WAPI.downloadFile(msg.clientUrl, function(result) {
        Store.CryptoLib.decryptE2EMedia(msg.type, result, msg.mediaKey, msg.mimetype).then(function(a) {
            const reader = new FileReader();
            reader.addEventListener('loadend', (e) => {
                callback(e.target);
            });
            reader.readAsDataURL(a._blob);
        }).catch(e => {
            console.error("Ошибка при декрипт ", e); // e = decrypt async missing payload
        })
    });
