You can order a new code signing certificate through K Software and take advantage of our discounted price even if you've ordered from Sectigo or any other CA in the past.
There is no special renewal process if you've purchased a certificate in the past. Place a new order using the same company information and the validation process should go much faster than your first order. All documentation is considered valid for 39 months. Even if you ordered outside that time frame your re-order will be faster. Be sure to quote your previous order number in any correspondence with Sectigo.
The certificate period starts from the issuance date of your new certificate - any time left on your old certificate won't be added to the new one. Because of that it is a good idea to order your new certificate a few weeks or less in advance of your expiration date (we'll email you to remind you).
K Software's FREE Point and Click Code Signing Utility
kSign will sign any number of files with your code signing certificate and comes with everything you need - no SDK or additional downloads required. Best of all - it's FREE!
kSign was written specifically for customers that have purchased code signing certificates through K Software. If you didn't purchase your certificate through K Software you can still use kSign for free but you'll be taken back to this website when the software signs a file.
A digital signature from an OV certificate won't guarantee your software isn't flagged by SmartScreen but signing helps ensure that your software's reputation can be recognized for everything you sign. A signature from an EV code signing certificate provides instant SmartScreen reputation and prevents the warning from ever appearing.
K Software has been providing affordable security certificates to developers for almost 15 years. Our code signing and SSL certificates are fully trusted on all modern Windows platforms (with legacy certificates for XP available) and most mobile platforms, MS-Office, Java, Flash and Adobe.
