Description

Klarseal serves as a code-signing certificate provider for developers and companies that are distributing Windows applications, drivers, or installers. It features both Standard (OV) and Extended Validation (EV) certificates that are issued by Certum, along with services for managing orders, invoices, application assessments, and status notifications. Utilizing cloud signing, both certificate types ensure that the private key is generated and securely stored within the certificate authority’s hardware security module, instead of being placed on a USB token. The Extended Validation option comprises additional identity verification processes and is a prerequisite for opening a Windows Hardware Developer Program account necessary for submitting kernel drivers. Additionally, Klarseal offers complimentary tools, including Sign my app, an MIT-licensed plugin that allows compatible AI coding agents to prepare Windows-file signing for user authorization, and Sign my app for Windows, a utility designed to check and digitally sign .exe, .dll, and .msi files, enhancing the overall workflow for developers. This comprehensive suite of tools not only simplifies the signing process but also enhances security and compliance for software distribution.
