Code Signing Certificates, Cloud Signing Options and Signing Operations Integration

What is a Code Signing Certificate?

A code signing certificate is a digital certificate that provides a globally accepted proof of identity of a software publisher and is obtainable from a reputable Certificate Authority (CA) like SSL.com. Software companies use code signing certificates to provide proof that they are the developers of an application.  Code signing certificates also prevent tampering of code and ensure that a file is free from unauthorized modifications, malware and is safe to install. Code signing certificates are an essential security feature when software is being distributed, sold, and downloaded online.  Digitally signing your code with trusted SSL.com certificates lets users and operating systems know that your software is authentic and safe to install. You can always contact our sales team to explain these options and provide a quote.

Choosing the Right Code Signing Certificate

Organization Validation (OV) and Individual Validation (IV) certificates are referred to as High Assurance certificates because they  require more validation and thus provide more trust, . For OV and IV certs, the CA will verify the actual organization or individual person that is attempting to get the certificate. The organization’s or individual’s name is also listed in the certificate, giving added trust that the certificate holder is reputable. OV certificates are often used by corporations, governments and other entities that want to provide an extra layer of confidence for their visitors. Aside from SSL/TLS certificates, OV and IV are also commonly used for code signing, document signing, client authentication, and S/MIME email certificates. For more information as to requirements, please refer to SSL.com’s OV and IV requirements. The Individual Validation (IV) Code Signing Certificate applies digital signatures with a personal name, perfect for independent software developers and individual project contributors who wish to increase confidence and trust from their users.  EV certificates provide the maximum amount of trust to visitors, and also require the most effort by the CA to validate. EV certificates may only be issued to businesses and other registered organizations, not to individuals. SSL.com Sole Proprietorship EV Code Signing Certificates add an individual’s identity to the standard EV code signing certificate. This validation option enables a sole proprietorship or individual contributor to include their name in the digital signature. The Sole Proprietorship validation option is also for enterprises that require an extra layer of security by including an individual’s validated identity in the digital signature. To know more about the features of these certificates, you can read our article,  Which Code Signing Certificate do I Need? EV or OV? At a quick glance, the defining features of OV and EV code signing certificates are listed below.

IV Code Signing Certificate:

  • Applies digital signatures with a personal name
  • Perfect for independent software developers and individual project contributors

OV Code Signing Certificate:

  • Verifies your identity as the software publisher
  • Shields your software from tampering and malware infection

EV Code Signing Certificate:

  • Ability to sign both pre-Windows 10 and Windows 10 Drivers
  • Instant Microsoft SmartScreen Reputation
  • Non-expiration of signature and time stamping
  •  Ability to Sign on the Cloud using eSigner
  • Sole Proprietorship EV Code Signing Certificates add an individual’s identity to the standard EV Code Signing Certificate

Setting up and Using Your SSL.com Account

If you haven’t already, start by creating an account on SSL.com. Your account has the capability of creating multiple teams as well as inviting multiple users with specific role and rights assignments.

The Validation Process

In order to validate and issue an OV or IV certificate, SSL.com must verify your identity, physical address, and telephone number via verifiable online resources and/or valid verification documents. For further details on the requirements, you can read What Are The Requirements for SSL.com OV and IV Certificates?  Additionally for IV Code Signing Certificate orders, applicants will have to submit a front and back image of an ID plus an image of them holding the ID next to their face. Per guidelines set by the CA/Browser Forum, extra documentation must be provided to issue an EV certificate. Head over to FAQ: Extended Validation (EV) Process to know all the requirements for EV certs. For entities requesting EV Code Signing Certificates, SSL.com will conduct validation both through trusted online resources and/or valid documents as well as extra documentation per guidelines set by the CA/Browser Forum.  

New key storage requirements for OV and IV Code Signing Certificates

In compliance with the CA/Browser Forum’s new key storage requirements for code signing certificates, starting on November 15 2022, SSL.com’s Organization Validation (OV) and Individual Validation (IV) Code Signing Certificates will only be issued either on Federal Information Processing Standard 140-2 (FIPS 140-2) USB tokens or through our eSigner cloud signing service.

Key Storage and Signing Methods for Extended Validation Code Signing Certificates 

USB Token

The most common approach to EV code signing is to use a Hardware Security Module (HSM) like a USB token which stores the EV Code Signing certificate and acts like a key in signing software code. Compared to storing the certificate on a local machine, a USB token scores well on handheld security and portability. One limitation to it though is that it can be quite expensive to buy and manage multiple tokens and they are not that flexible when compared to cloud-based options.  SSL.com provides secure private key storage and physical 2FA security with a Yubikey FIPS USB Token. This USB device adds anti-tampering protection to your software because only those individuals who have actual possession of it will be allowed to digitally sign a code to your applications or programs.

Cloud HSM

A second option for EV code signing is to use a networked HSM in the cloud to host code signing certificates and keys. This method offers a comparable level of security as a USB token since the private keys are also not exportable. Because code signing is conducted through the cloud, a scalable collaboration among developers is achieved. It should be noted though that this method may require expertise with the particular cloud service provider. For the issuance of EV code signing certificates, SSL.com supports three Cloud HSMs: Microsoft Azure Dedicated HSM, Amazon Web Services (AWS) CloudHSM, and Google Cloud HSM. To get more details on each one, you can read our guide article: Supported Cloud HSMs for Document Signing and EV Code Signing.
  • To know how you can use your HSM account and hire a professional for Cloud HSM Attestation, you can read our article Bring Your Own Auditor Cloud HSM Attestation.
  • SSL.com is currently developing and testing attestation procedures for a wide range of HSM platforms. You can fill out this inquiry form to find out if we are testing an HSM platform that was not listed above.

eSigner: Code Signing as a Service

Thirdly, a modern and very convenient approach to EV Code Signing is dealing with code signing as a service. SSL.com’s eSigner cloud code signing service is an example of this method.  With eSigner, SSL.com handles both the public key infrastructure (PKI) and HSMs for code signing. The non-exportable signing keys are stored in eSigner’s HSMs, where neither the customer nor SSL.com can view them. This way, the security standard is as high as with tokens and cloud HSMs, but there is no need for the client to deal with them directly. The eSigner environment includes a number of signing options to accommodate the needs of a variety of customers, from individual developers to complex organizations.

eSigner Signing Options

  • With SSL.com’s eSigner service, you can use your SSL.com Extended Validation Code Signing Certificate to sign code from any internet-connected device without any additional hardware. After enrolling your EV Code Signing certificate order in eSigner, you can sign code with either the eSigner Express web app, eSigner CodeSignTool or through SSL.com’s CSC-compliant code signing API
