NAME

swtpm-localca.conf - Configuration file for swtpm_localca

DESCRIPTION

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:

The name of a directory where to store data into. A lock will be created in this directory.
The file containing the key used for signing the certificates. Provide a key in PEM format or a pkcs11 URI.
The password to use for the signing key.
The file containing the certificate for this CA. Provide a certificate in PEM format.
The name of file containing the serial number for the next certificate.
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.
This variable can be set to the port on which tcsd is listening for connections. By default port 30003 will be used.
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.

EXAMPLE

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
