9 FAPI configuration file
10
11 The FAPI parameters which can be adjusted via the configuration file
12 are;
13
14 · profile_name: Name of the default cryptographic profile chosen from
15 the profile_dir directory.
16
17 · profile_dir: Directory that contains all cryptographic profiles known
18 to FAPI.
19
20 · user_dir: The directory where user objects are stored.
21
22 · system_dir: The directory where system objects, policies, and import‐
23 ed objects are stored.
24
25 · tcti: The TCTI interface which will be used.
26
27 · system_pcrs: The PCR registers which are used by the system.
28
29 · log_dir: The directory for the event log.
30
31 · ek_cert_less: A switch to disable certificate verification (option‐
32 al).
33
34 · ek_fingerprint: The fingerprint of the endorsement key (optional).
35
36 If not otherwise specified during TSS installation, the default loca‐
37 tion for the exemplary profiles is /etc/tpm2-tss/profiles/ and
38 /etc/tpm2-tss/ for the FAPI configuration file. The environment vari‐
39 able TSS2_FAPICONF can be used to set an alternative pathname for the
40 FAPI configuration file.
41
43 The FAPI configuration file is JSON encoded:
44
45 {
46 "profile_name": "P_ECCP256SHA256",
47 "profile_dir": "/etc/tpm2-tss/fapi-profiles/",
48 "user_dir": "~/.local/share/tpm2-tss/user/keystore/",
49 "system_dir": "/home/myhome/keystore/system/keystore",
50 "tcti": "",
51 "system_pcrs" : [0, 1, 2, 3, 4, 5, 6, 7],
52 "log_dir" : "/home/myhome/eventlog/"
53 }
54
55 For this example the default TCTI of the system will be used. The cer‐
56 tificates for the stored endorsement keys will be checked. If the cer‐
57 tificate checking is not needed the option:
58
59 "ek_cert_less": "yes" can be added to the config file. Alternative to
60 the standard certificate checking a fingerprint (hash of the public
61 key) for the stored endorsement key can be defined in the config file:
62
63 "ek_fingerprint": { "hashAlg" : "sha256", "di‐
64 gest" : "9e56...214d" }
