Constants

const (
	// SevSnp is a constant denotes device name for teeTechnology
	SevSnp = "sev-snp"
)

Add constants for other devices when required

Variables

var ExternalTPM io.ReadWriter

ExternalTPM can be set to run tests against an TPM initialized by an external package (like the simulator). Setting this value will make all gotpm commands run against it, and will prevent the cmd package from closing the TPM. Setting this value and closing the TPM must be managed by the external package. ExternalTPM can have a TPM simulator or a real TPM.

var RootCmd = &cobra.Command{
	Use: "gotpm",
	Long: `Command line tool for the go-tpm TSS

This tool allows performing TPM2 operations from the command line.
See the per-command documentation for more information.`,
	PersistentPreRunE: func(cmd *cobra.Command, args []string) error {
		if quiet && verbose {
			return fmt.Errorf("cannot specify both --quiet and --verbose")
		}
		cmd.SilenceUsage = true
		return nil
	},
}

RootCmd is the entrypoint for gotpm.
