GlobalSign Root Certificates

May 8, 2025

Overview

GlobalSign's root certificates are some of the most trusted root certificates in the PKI ecosystem. Since our inception, we have generated future-proof root certificates that exceed current industry best practices. We work diligently to protect the security of our root certificates, providing end users with trust anchors that secure all types of organization and individual authentication.

The major Browsers and Root programs have set requirements in place to create and use "single-purpose" roots, so different use-cases and applications will use their respective roots. Starting in 2019 and continuing into 2020, GlobalSign created new single-purpose roots, which are listed below.

To find out which products are using what roots, please see this page: https://support.globalsign.com/ca-certificates/intermediate-certificates 

Multi-Purpose Roots

R1 GlobalSign Root Certificate

GlobalSign Root R1
SHA1 • RSA • 2048

Valid until: 28 January 2028
Serial #: 04:00:00:00:00:01:15:4b:5a:c3:94
Thumbprint: b1:bc:96:8b:d4:f4:9d:62:2a:a8:9a:81:f2:15:01:52:a4:1d:82:9c

Root R1 was GlobalSign’s first root certificate embedded in browsers (back in 1999, Netscape and Windows 98), making Root R1 GlobalSign’s oldest and most ubiquitous root certificate. The original use case was for personal certificates, but this quickly expanded as GlobalSign’s business and expertise broadened. Due to its hash algorithm, GlobalSign will begin scaling back Root R1 use.

R3 GlobalSign Root Certificate

GlobalSign Root R3
SHA256 • RSA • 2048

Valid until: 18 March 2029
Serial #: 04:00:00:00:00:01:21:58:53:08:a2
Thumbprint: d6:9b:56:11:48:f0:1c:77:c5:45:78:c1:09:26:df:5b:85:69:76:ad

Root R3 is GlobalSign’s second oldest root, and as ubiquitous as Root R1. Its hash algorithm is more secure than R1, and therefore all of GlobalSign’s business (TLS, code signing, timestamping document signing) chains to this root.

R5 GlobalSign Root Certificate

GlobalSign ECC Root R5
SHA384 • ECC • 384

Valid until: 19 January 2038
Serial #: 60:59:49:e0:26:2e:bb:55:f9:0a:77:8a:71:f9:4a:d8:6c
Thumbprint: 1f:24:c6:30:cd:a4:18:ef:20:69:ff:ad:4f:dd:5f:46:3a:1b:69:aa

Root R5 is GlobalSign’s first ECC root, providing customers a pure ECC hierarchy. It features a SHA-384 hash with a 384-bit key length, making it one of GlobalSign’s most secure roots in the PKI ecosystem. It has been embedded in every major browser and security trust list.

R6 GlobalSign Root Certificate

GlobalSign Root R6
SHA384 • RSA • 4096

Valid until: 10 December 2034
Serial #: 45:e6:bb:03:83:33:c3:85:65:48:e6:ff:45:51
Thumbprint: 80:94:64:0e:b5:a7:a1:ca:11:9c:1f:dd:d5:9f:81:02:63:a7:fb:d1

Root R6 is GlobalSign’s most secure, robust RSA root. At SHA-384 with a 4096-bit key length, it is poised to take on most of GlobalSign’s core business, especially as Root R3 retires. It has been embedded in every major browser and security trust list.

Trusted Root Intermediate Certificates

Feb 27, 2020, 2:11 AM

This support article is all about Trusted Root Intermediate Certificates, a select service with strict requirements. PKI hierarchies allow you to control the chain of trust in your ecosystem, whether you’re implementing client authentication within an enterprise or deploying secure device identities within a supply chain. GlobalSign supports multiple hierarchy options for more flexible trust management and isolation of control, including dedicated or shared and public or private models. GlobalSign Root Certificates are already distributed in all operating systems, browsers, and mobile devices, meaning that all certificates issued from hierarchies beneath these roots are transparently trusted. For closed ecosystems, where public trust isn’t wanted or allowed, private and dedicated customer roots and intermediates are issued.

Root & Intermediate Certificate Bundles

Mar 9, 2020, 2:50 PM

Some Apache and Java based applications require the Root & Intermediate certificates to be bundled in a single file. You can create a certificate bundle by opening a plain text editor (notepad, gedit, etc) and pasting in the text of the root certificate and the text of the intermediate certificate. The order they go in depends on the type of server you are running. Nginx for example concatenates all certificates in one file beginning with the server certificate.

GlobalSign Qualified Production and Sample Certificates

Mar 10, 2020, 10:24 AM

This support article lists down the Qualified Production Certificate and Qualified Sample Certificate. Qualified certificates can only be issued by a Qualified Trust Service Provider (QTSP) recognized under eIDAS. GlobalSign is recognized across all EU and EEA countries as a QTSP and has undergone the appropriate eIDAS conformity assessments in order to be able to provide qualified certificates for website authentication and electronic seals. All certificates, signatures, and seals are compliant with EU regulations and local signing standards.
