9 The file /etc/swtpm-localca.conf contains configuration variables for
10 the swtpm_localca program.
11
12 Entries may contain environment variables that will be resolved. All
13 environment variables must be formatted like this: '${varname}'.
14
15 Users may write their own configuration into
16 ${XDG_CONFIG_HOME}/swtpm-localca.conf or if XDG_CONFIG_HOME is not set
17 it may be in ${HOME}/.config/swtpm-localca.conf.
18
19 The following configuration variables are supported:
20
21 statedir
22 The name of a directory where to store data into. A lock will be
23 created in this directory.
24
25 signinkey
26 The file containing the key used for signing the certificates.
27 Provide a key in PEM format or a pkcs11 URI.
28
29 signingkey_password
30 The password to use for the signing key.
31
32 issuercert
33 The file containing the certificate for this CA. Provide a
34 certificate in PEM format.
35
36 certserial
37 The name of file containing the serial number for the next
38 certificate.
39
40 TSS_TCSD_HOSTNAME
41 This variable can be set to the host where tcsd is running on in
42 case the signing key is a GnuTLS TPM 1.2 key. By default localhost
43 will be used.
44
45 TSS_TCSD_PORT
46 This variable can be set to the port on which tcsd is listening
47 for connections. By default port 30003 will be used.
48
49 env:<environment variable name=<value>>
50 Environment variables, that are needed by pkcs11 modules, can be
51 set using this format. An example for such an environment variable
52 may look like this:
53
54 env:MY_MODULE_PKCS11_CONFIG = /tmp/mymodule-pkcs11.conf
55
56 The line must not contain any trailing spaces.

59 An example swtpm-localca.conf file may look as follows:
60
61 statedir = /var/lib/swtpm_localca
62 signingkey = /var/lib/swtpm_localca/signkey.pem
63 issuercert = /var/lib/swtpm_localca/issuercert.pem
64 certserial = /var/lib/swtpm_localca/certserial
65
66 With a PKCS11 URI it may look like this:
67
68 statedir = /var/lib/swtpm-localca
69 signingkey = pkcs11:model=SoftHSM%20v2;manufacturer=SoftHSM%20project;serial=891b99c169e41301;token=mylabel;id=%00;object=mykey;type=public
70 issuercert = /var/lib/swtpm-localca/swtpm-localca-tpmca-cert.pem
71 certserial = /var/lib/swtpm-localca/certserial
72 SWTPM_PKCS11_PIN = 1234
