Where does openssl.cnf live in Windows?

[s.doig]

MainWP Dashboard on Local WP can’t connect to a remote child site.

When connecting a site to my localhost MainWP (powered through WP Local), I get a 500 error for /wp-admin/admin-ajax.php.

Debug gives an error:

PHP Fatal error: Uncaught TypeError: openssl_pkey_get_details(): Argument #1 ($key) must be of type OpenSSLAsymmetricKey, bool given in C:\Users\Steve\Local Sites\mainwp-volunteer\app\public\wp-content\plugins\mainwp\class\class-mainwp-manage-sites-view.php:1550

If I visit MainWP Advanced Settings, OpenSSL.cnf location is set to C:\Program Files\Common Files\SSL\openssl.cnf

However, the SSL folder does not exist in C:\Program Files\Common Files\

Where can I find the Local WP openssl.cnf file in Windows?

Hi @s.doig

I don’t have a Windows set up to be able to look, but I might have a workaround. Can you try the following?

Go to the WP > Settings > MainWP Child > Settings page.

From there, Deselect the Require Unique Security ID option and Click the Save Changes button.

Hi Nick,

The security ID is unrelated to open.ssl (it is a text string), and turning it off would leave MainWP child sites vulnerable.

Thanks,
Steve

openssl.cnf

Hi @s.doig Sorry for my misunderstanding. These threads below might be helpful to you:

Trying To Use MainWP On Local But Keep Getting An Error When Trying To Connect Sites

The path to OpenSSL is in the phpinfo button. With the site active, from Local, click on the “circle I” (info) icon next to the php version. It will display the php info page. Somewhere on that page you will see an entry for OpenSSL. There will be a file path. Use that one. Sorry I’m on my iPad, no images for help. I had this issue too. I had to got back to the MainWP setup wizard. I think I had to select localhost > Windows even though I was on a Mac.

MainWP, curl, SSL and other errors

This is a fairly complicated part of Local that to be honest, I don’t 100% understand. Also, I’ve never used MainWP, but as I understand it, it’s a tool that allows you to administer multiple WordPress sites from one central place – is that correct? If so, how is the main controller/admin functionality implemented? Is it a plugin that needs to be installed on a WordPress site? Also I’m guessing that each individual “secondary” site needs some sort of worker plugin – is that correct? In terms o…

Hi Nick-B,

RE: the first link, Local reports the link to openssl.cnf is:
C:\Program Files\Common Files\SSL/openssl.cnf

but the SSL folder does not exist in the Common Files folder, so Local is mistaken.

RE: the second link, this doesn’t contain any solutions.

Hi @s.doig

The link that first one shows that it should be found here: /usr/lib/ssl/openssl.cnf

But I see some additional notes from @DigiRik that might help here:

Trying To Use MainWP On Local But Keep Getting An Error When Trying To Connect Sites

@afragen You’re not gonna believe this. The first path I tried worked! I looked through the paths one by one and most of them looked like they were associated with Wordpress plugins but then I came across one that looked more like the examples I’d seen in one of my Google searches and it worked. For anyone having the same issue here are the steps I followed: Install MainWP on the Wordpress installation running on LocalWP using all default settings In the MainWP dashboard navigate to Setting…

The link that first one shows that it should be found here: /usr/lib/ssl/openssl.cnf

That is not a Windows path… It is Unix/Mac.

But I see some additional notes from @DigiRik that might help here:

That does not mention a Windows path either. It is Unix/Mac.

@s.doig Sorry for my mistake there.

The openssl.cnf file for Localwp should be found in the following location on Windows:

C:\Users\<username>\AppData\Roaming\Local\run\router\openssl.cnf

Note that <username> should be replaced with your Windows user account name.

If you still can’t find that directory, can you try searching for it using Windows Search? You should be able to search openssl.cnf after pressing the Windows key.

[s.doig]

No worries.

That directory does not contain the openssl.cnf file, only a nginx folder.

[Nick-B]

Were you able to locate it using the Windows search function?
