Button: Show MD5/SHA

Overview:

This script-button calculates the hashes of selected files and displays them in a dialog:

Snipaste_2019-05-07_09-35-47

Download:

Alternatively, here is the same button in the form of a User Command:

  • showHASH.zip (797 Bytes)
  • Extract the zip and copy the file to /dopusdata\User Commands in Opus, and you will then find it under Settings > Customize Toolbars > Commands > User-Defined Commands where you can drag it to a toolbar.

Script Code:

The script code inside the downloads above is reproduced here for reference:

function OnClick(clickData)
{
	if (clickData.func.sourcetab.selected.count == 0)
	{
		var dlg= DOpus.Dlg;
		dlg.message="Please select a file!";
		dlg.Show;
       return;
	}
	else
	{
		for (var eSel = new Enumerator(clickData.func.sourcetab.selected); !eSel.atEnd(); eSel.moveNext())
		{
			if (eSel.item().is_dir)
			{
				var dlg= DOpus.Dlg;
			    dlg.message=eSel.item().RealPath +" is fold, not a file!";
				dlg.Show;
			}
			else
			{
			    var md5=DOpus.FSUtil.Hash(eSel.item().RealPath,"md5");
				var sha1=DOpus.FSUtil.Hash(eSel.item().RealPath,"sha1");
				var sha256=DOpus.FSUtil.Hash(eSel.item().RealPath,"sha256");
				var dlg= DOpus.Dlg;
				dlg.message=eSel.item().RealPath + "\r\n\r\n\r\n MD5:\t\t" +md5 +"\r\n\r\n SHA-1:\t" +sha1+"\r\n\r\n SHA-256:\t"+sha256;
				dlg.buttons="Copy+Copy Md5+Copy Sha1+Copy Sha256|Close"
				dlg.Show;

				switch(dlg.result)
				{
					case 1:
						DOpus.SetClip(dlg.message);
					break;
					case 2:
						DOpus.SetClip(md5);
					break;
					case 3:
						DOpus.SetClip(sha1)
					break;
					case 4:
						DOpus.SetClip(sha256)
					break;
					
				}
			}
		}
	}
}

Not something I'll use right now but looks like the dialog box should be widened when the hash is too long.

I used two Tab.

you can delete them.

I can't align the values in the window and even the sha 256 is only partially displayed ..
I can also show the CRC32?
How do I fix it?
Thanks

Here's a version that supports CRC32 and displays SHA256 with a line break.

function OnClick(clickData) {
    var tab = clickData.func.sourcetab;
    var dlg = clickData.func.Dlg();
    var fsu = DOpus.FSUtil();

    if (tab.selected_files.count == 0) {
        dlg.Request('Please select at least one file!', 'OK');
    } else {
        for (var eSel = new Enumerator(tab.selected_files); !eSel.atEnd(); eSel.moveNext()) {
            var item = eSel.item();
            var md5 = fsu.Hash(item, 'md5');
            var sha1 = fsu.Hash(item, 'sha1');
            var sha256 = fsu.Hash(item, 'sha256');
            var crc32 = fsu.Hash(item, 'crc32');

            dlg.message = item + '';
            dlg.message += '\n\nCRC32:\n' + crc32;
            dlg.message += '\n\nMD5:\n' + md5;
            dlg.message += '\n\nSHA1:\n' + sha1;
            dlg.message += '\n\nSHA256:\n' + sha256.substr(0, 32) + '\n' + sha256.substr(32);

            dlg.buttons = 'Copy+Copy CRC32+Copy MD5+Copy SHA1+Copy SHA256|Cancel';
            dlg.Show;

            switch (dlg.result) {
                case 0:
                    exit;
                case 1:
                    DOpus.SetClip(dlg.message);
                    break;
                case 2:
                    DOpus.SetClip(crc32);
                    break;
                case 3:
                    DOpus.SetClip(md5);
                    break;
                case 4:
                    DOpus.SetClip(sha1);
                    break;
                case 5:
                    DOpus.SetClip(sha256);
                    break;
            }
        }
    }
}

This version of lxp's script should be slightly quicker for large files:

function OnClick(clickData) {
    var tab = clickData.func.sourcetab;
    var dlg = clickData.func.Dlg();
    var fsu = DOpus.FSUtil();

    if (tab.selected_files.count == 0) {
        dlg.Request('Please select at least one file!', 'OK');
    } else {
        for (var eSel = new Enumerator(tab.selected_files); !eSel.atEnd(); eSel.moveNext()) {
            var item = eSel.item();
            varHashes = fsu.Hash(item, 'md5,sha1,sha256,crc32');
            var md5 = varHashes(0);
            var sha1 = varHashes(1);
            var sha256 = varHashes(2);
            var crc32 = varHashes(3);

            dlg.message = item + '';
            dlg.message += '\n\nCRC32:\n' + crc32;
            dlg.message += '\n\nMD5:\n' + md5;
            dlg.message += '\n\nSHA1:\n' + sha1;
            dlg.message += '\n\nSHA256:\n' + sha256.substr(0, 32) + '\n' + sha256.substr(32);

            dlg.buttons = 'Copy+Copy CRC32+Copy MD5+Copy SHA1+Copy SHA256|Cancel';
            dlg.Show;

            switch (dlg.result) {
                case 0:
                    return;
                case 1:
                    DOpus.SetClip(dlg.message);
                    break;
                case 2:
                    DOpus.SetClip(crc32);
                    break;
                case 3:
                    DOpus.SetClip(md5);
                    break;
                case 4:
                    DOpus.SetClip(sha1);
                    break;
                case 5:
                    DOpus.SetClip(sha256);
                    break;
            }
        }
    }
}

Changed:

var md5 = fsu.Hash(item, 'md5');
var sha1 = fsu.Hash(item, 'sha1');
var sha256 = fsu.Hash(item, 'sha256');
var crc32 = fsu.Hash(item, 'crc32');

to:

varHashes = fsu.Hash(item, 'md5,sha1,sha256,crc32');
var md5 = varHashes(0);
var sha1 = varHashes(1);
var sha256 = varHashes(2);
var crc32 = varHashes(3);

So all the hashes are calculated at once.

Also changed exit to break return near the end, to fix the error when cancelling the dialog.

Thanks. Meant to write return to get out of the for loop.

Many thanks !!!!!

Ah, that makes sense. I wondered why it was different but missed that.

I've edited it in my post above to do that.
