swtpm−localca.conf − Configuration file for swtpm_localca
The file /etc/swtpm−localca.conf contains configuration variables for the swtpm_localca program.
Entries may contain environment variables that will be resolved. All environment variables must be formatted like this: ’${varname}’.
Users may write their own configuration into ${XDG_CONFIG_HOME}/swtpm−localca.conf or if XDG_CONFIG_HOME is not set it may be in ${HOME}/.config/swtpm−localca.conf.
The following
configuration variables are supported:
statedir
The name of a directory where to store data into. A lock will be created in this directory.
signinkey
The file containing the key used for signing the certificates. Provide a key in PEM format or a pkcs11 URI.
signingkey_password
The password to use for the signing key.
issuercert
The file containing the certificate for this CA. Provide a certificate in PEM format.
certserial
The name of file containing the serial number for the next certificate.
TSS_TCSD_HOSTNAME
This variable can be set to the host where tcsd is running on in case the signing key is a GnuTLS TPM 1.2 key. By default localhost will be used.
TSS_TCSD_PORT
This variable can be set to the port on which tcsd is listening for connections. By default port 30003 will be used.
env:<environment variable name=<value>>
Environment variables, that are needed by pkcs11 modules, can be set using this format. An example for such an environment variable may look like this:
env:MY_MODULE_PKCS11_CONFIG = /tmp/mymodule−pkcs11.conf
The line must not contain any trailing spaces.
An example swtpm−localca.conf file may look as follows:
statedir =
/var/lib/swtpm_localca
signingkey = /var/lib/swtpm_localca/signkey.pem
issuercert = /var/lib/swtpm_localca/issuercert.pem
certserial = /var/lib/swtpm_localca/certserial
With a PKCS11 URI it may look like this:
statedir =
/var/lib/swtpm−localca
signingkey =
pkcs11:model=SoftHSM%20v2;manufacturer=SoftHSM%20project;serial=891b99c169e41301;token=mylabel;id=%00;object=mykey;type=public
issuercert =
/var/lib/swtpm−localca/swtpm−localca−tpmca−cert.pem
certserial = /var/lib/swtpm−localca/certserial
SWTPM_PKCS11_PIN = 1234
