Before we get into how you can create a self signed code signing certificate<\/a>, let\u2019s understand what it is, how it is different from the ones offered by a third-party certificate authority (CA), and which one is more suited for your specific needs. Without further ado, let\u2019s jump right in!<\/p>\n\n\n\n

What Is a Code Signing Certificate?<\/strong><\/h2>\n\n\n\n

A code signing certificate is a data file that places a cryptographic digital signature on your code. I say cryptographic because I don\u2019t want some of you to think of it as a digitized version of the signature doodles you made at the back of your notebook as a child. <\/p>\n\n\n\n

This digital signature is mathematically derived, and it\u2019s used to authenticate your identity. Code signing also makes tampering with your program a lot harder, so any hacker will have a hard time modifying your code to run malicious scripts. This not only tells your userbase who\u2019s the software publisher, but it also assures them that an attacker hasn\u2019t altered the file since it was last signed. This process builds trust in users and strengthens their digital safety. <\/p>\n\n\n\n

Since Microsoft trusts reputable commercial certificate authorities (also known as CAs), and they\u2019re essentially vouching for you, security warnings like \u201cUntrusted Publisher\u201d may well be evaded, and that could have a potential direct impact on your conversion rates! Moreover, EV code signing certificates<\/a> from trusted CAs are your only hope against Microsoft SmartScreen filter, which tends to be extremely wary about the code they trust.<\/p>\n\n\n\n

What Is a Self Signed Code Signing Certificate?<\/strong><\/h2>\n\n\n\n

A self signed code signing certificate is,\nas the name suggests, signed by you (the software publisher) instead of a\ntrusted third party. It works like a regular code signing certificate but only\nfor you because only you trust your signature. Not sure what we mean? Let us\nexplain a little more.<\/p>\n\n\n\n

With a self signed code signing\ncertificate, you\u2019re essentially vouching for yourself and saying that you can\nbe trusted. The issue is that machines and browsers don\u2019t have your public key\nin their trust root store (because you\u2019re presumably not a well-known CA) and,\nhence, they have no reason to trust you. Additionally, good luck getting your\nsignature timestamped if you\u2019re using a self signed code signing certificate. <\/p>\n\n\n\n

Nevertheless, you can use self signed code\nsigning certificates for internal purposes, or in testing environments.\nHowever, it\u2019s best to use it for internal use only. That\u2019s because, if you\u2019re\nreleasing a product to be used by customers with a self signed certificate, it\nwill generate a security alert.<\/p>\n\n\n\n

How to Create a Self Signed Code Signing Certificate<\/strong><\/h2>\n\n\n\n

You can create a self signed code signing certificate using OpenSSL<\/a>. Or, for Windows 10 users, you can use PowerShell\u2019s New-SelfSignedCertificate, an automated script that makes the job of creating such certificates easier for you. Just type in the command below to add your certificate to the certificate store:<\/p>\n\n\n\n

$cert = New-SelfSignedCertificate -DNSName \"www.domain.com\" -CertStoreLocation Cert:\\CurrentUser\\My -Type CodeSigningCert -Subject \u201cExample Code Signing Certificate\u201d<\/code><\/pre>\n\n\n\n

<\/div>\n\n\n\n
You can also add the certificate as a trusted certificate authority for your network using mmc.exe and a certificate manager. You will need to add certificates snap-in for computer account and local accounts. Once that\u2019s done, in the certificate manager, copy your self signed code signing certificate from the Personal folder and expand and paste it in the Certificates <\/strong>folder under Trusted Root Certificate Authority<\/strong>.<\/p>\n\n\n\n
