GPG Smart Card Daemon (recommended)
DigiCert® Software Trust Manager GPG Smart Card Daemon (SCD) is a GPG compliant SCD client-side tool that integrates with the GPG-agent (part of the GPG tool suite) for all GPG based hash signing use cases. The GPG SCD handles secure key generation, application hash signing, and associated certificate-related requirements when the signing request does not require the transportation of files and intellectual property.
