Oh, and the revocation link doesn’t work: no file.

Fixed now.

I can’t find the previous (bad) certificate in the certification manager.

Maybe you used for the N++ cert “Store location” Local Machine instead of the Current User?

If so, try to launch “certlm.msc” MMC snap-in instead of the above mentioned “certmgr.msc”.

The latest, and I believe the last update:
http://download.notepad-plus-plus.org/repository/8.x/8.8.3.RC4/

Very sorry about that. Some errors have been found in the certificate and I have had to regenerate the ROOT CA & the signing certificate.
Anyway, it seems all OK now, so I can promise you it’s the last one.

@xomx Thank you. When I downloaded and installed the certificate from https://notepad-plus-plus.org/nppRoot.crt that the installer process popped up:

---------------------------
Security Warning
---------------------------
You are about to install a certificate from a certification authority (CA) claiming to represent:

Notepad++

Windows cannot validate that the certificate is actually from "Notepad++". You should confirm its origin by contacting "Notepad++". The following number will assist you in this process:

Thumbprint (sha1): C4E7785B 6DD1DAF2 AEDE5C99 4BB3D495 AF7B45AB

Warning:

If you install this root certificate, Windows will automatically trust any certificate issued by this CA. Installing a certificate with an unconfirmed thumbprint is a security risk. If you click "Yes" you acknowledge this risk.

Do you want to install this certificate?

---------------------------
Yes   No   
---------------------------

The thumbprint C4E7785B 6DD1DAF2 AEDE5C99 4BB3D495 AF7B45AB is not mentioned in the user manual. I tried Google for “C4E7785B 6DD1DAF2 AEDE5C99 4BB3D495 AF7B45AB” and then “C4E7785B6DD1DAF2AEDE5C994BB3D495AF7B45AB” but it was not found.

I have no issue with v8.8.2

But with v8.8.3 (all RC), installed the cert. (checked in Local Machine & Current User), i have the issue (newly program detected) by Trend Apex One (my company).

Thanks for your support, Notepad++ is my favorite editor. I’m currenty using portable edition.

@donho , did you want to add the links to the Root CA and CRL files on https://notepad-plus-plus.org/resources/ , along with the thumbprints for the Root CA and the current signing certificate you are using?

Since you have the GPG there, it makes sense to also share the details of the new CA and signing certs there as well.

I could then have the Manual link to that page for people to confirm the thumbprints for the certs.

The paths of revocation list (crl) and root certificate are indicated in the Notepad++ code signing certificate (you can find them in the section “Details”):

CRL Distribution Point:

[1]CRL Distribution Point
     Distribution Point Name:
          Full Name:
               URL=http://notepad-plus-plus.org/nppRevoke.crl

Authority Information Access:

[1]Authority Info Access
     Access Method=Certification Authority Issuer (1.3.6.1.5.5.7.48.2)
     Alternative Name:
          URL=http://notepad-plus-plus.org/nppRoot.crt

So, firstly if we want to move these 2 files to resources directory, this code signing certificate should be revoked, then a new certificate can be regenerated with 2 modified paths. the RC should be signed again and RC5 should be checked again by the community…

Secondly, since such information is imposed by the certificate, for me
URL=http://notepad-plus-plus.org/nppRoot.crt
looks more serious then
URL=http://notepad-plus-plus.org/resources/nppRoot.crt,
and they are more accessible for the antivirus vendors, IT ppl & users (just under the root - shorter and simpler).

For the above reasons, let’s keep it as it is. If it’s really bothering, we can always change in 3 years.

@donho ,

Sorry, I think I didn’t communicate clearly enough. I meant add a paragraph/section to the page at https://notepad-plus-plus.org/resources/ , which will link to the files which can stay at https://notepad-plus-plus.org/nppRoot.crt and https://notepad-plus-plus.org/resources/nppRoot.crt , and give details about those files, just like you do for the “Release Key”. Something like:

You don’t have to use exactly that phrasing – I just mocked it up similar to what you had in the earlier section on that page.

<h2>Self-Signed Root Certificate Authority & Signing Key</h2>
<p>Notepad++ currently uses its own Root Certificate Authority (CA) for creating signing keys.
</p>
<ul>
    <li>URL = <a href="https://http://notepad-plus-plus.org/nppRoot.crt">https://http://notepad-plus-plus.org/nppRoot.crt</a></li>
    <li>Issued to: Notepad++</li>
    <li>Issued by: Notepad++</li>
    <li>Valid from 7/7/2025 to 7/7/2055</li>
    <li>Thumbprint = <tt>c4e7785b6dd1daf2aede5c994bb3d495af7b45ab</tt></li>
    <li>Revocation List = <a href="https://notepad-plus-plus.org/nppRevoke.crl">https://notepad-plus-plus.org/nppRevoke.crl</a></li>
    <li>Instructions = See the <a href="https://npp-user-manual.org/docs/getting-started/#notepad-self-signed-certificate-authority-for-binaries">User Manual: Getting Started: Self-Signed Certificate Authority</a></li>
</ul>
<p>The current signing certificate has the following details:</p>
<ul>
    <li>Issued to: Notepad++</li>
    <li>Issued by: Notepad++</li>
    <li>Valid from 7/7/2025 to 7/7/2028</li>
    <li>Thumbprint = <tt>1c20840863e00c00bcdc30362121693e54966a28</tt></li>
</ul>

This information will allow people to verify that they have correctly downloaded the right Root Certificate Authority, similar to the way you let them verify the GPG signature.

To sum up: I wasn’t asking you to change the URL of the certs or to re-issue them. I was asking you to publish the data about them on the main website, similar to the way you publish the data about the GPG signature on the main website.

Yes, you’re right - I forgot the part of resources!
I will add the information into this page, so it will be available during the release process.
Thank you for the reminding!

Maybe I’m a little bit lost in all that RC versions, but now I dl again the RC4 ones x64 installer and it’s signed like the above statements, which is just wrong, isn’t it? (should be with https instead):

Edit: Seems like MS own signed executables have the same http-only.
