Sectigo Code Signing certificates digitally sign your code to increase user trust and reduce security warnings

The internet is not a trusting place, the days of people putting blind faith into downloads is long gone. The benefit of the doubt is dead. Nowadays you need to assert your identity as a publisher when you present internet users with your software. They need certain assurances. Before anyone downloads software nowadays they want to know who made it and whether or not it comes as intended—free from tampering on unauthorized alterations. Sectigo Code Signing certificates can deliver this. Digitally signing your software with a Sectigo code signing certificate provides the necessary assurances: asserting publisher identity and ensuring software integrity.

Get rid of security warnings

Without code signing, browsers and antivirus programs will flag your software as suspicious and issue warnings of varying severity. This is a true conversion killer, as most people are loath to disobey these warnings. But with a digital signature made by your Sectigo Code Signing certificate those same browser filters and antiviruses will display your organization and individual name as the publisher, along with assurance about the software's integrity. This is how it's supposed to be, but it's only possible with a Sectigo Code Signing certificate.

How does Code Signing work?

Code Signing works by affixing a digital signature to a piece of software and then performing a one-way hashing process to monitor the integrity of the signed code. There are two main purposes for Code Signing:

  • Asserting the identity of the publisher
  • Monitoring for software compromise

The way it works is fairly simple: upon completing a piece of software or code, the publisher uses the certificate's private key to apply its own unique digital signature. The signature and the software are then hashed--that's a one-way process where data of any length is mapped to a fixed length output called a hash value or digest.

When an internet user attempts to download the signed software, their system will validate the digital signature using PKI to ensure the signature is authentic. Then it will perform the same hash function that occurred during the signing and compare the values. If anything has changed with the signed code, even the tiniest tweak, it will produce a completely different hash value. So, upon repeating the hashing step, if the two digests aren't the same the software has clearly been tampered with. If they do match, the download proceeds as planned. This all occurs behind the scenes in a matter of milliseconds.

Sectigo Code Signing certificates are some of the most widely-trusted in the world, combining functionality with affordability in a way many other Certificate Authorities can't match. Additionally, Sectigo is one of the last CAs still selling certificates to individual developers, too.

"Very fast delivery. Installation was easy with no problems. If you are installing a wildcard SSL certificate on cPanel, you need to specify the actual domain name, don't try to install it on * , you have to install it on each subdomain such as,,..etc. Use the same certificate for each subdomain you install. Good luck!"
