NAME

6       tssimaextend - Replay the IMA event log
7

DESCRIPTION

9       Replays the provided IMA event log.
10
11       Without -sim, uses TPM2_PCR_Extend to extend the events into the TPM.
12       With    -sim, extends into simulated PCRs and traces the result.
13
14       Without -sim, hash algorithms not allocated are ignored, the TPM behav‐
15       ior.
16       With    -sim, all specified hash algorithms are used.  If no hash algo‐
17       rithms are specified, defaults to sha1 and sha256.
18
19       Two IMA log formats are currently supported:
20
21       1: SHA1 - A zero padded measurement is extended into other PCR banks.
22       2:  SHA1  -  A  digest  of the template data is extended into other PCR
23       banks.
24
25       This handles the case where a zero measurement extends  ones  into  the
26       IMA PCR.

28       -if    IMA event log file name
29
30       [-of   With -sim, PCR 10 of first algorithm specified]
31
32       [-le   input file is little endian (default big endian)]
33
34       [-halg (sha1, sha256, sha384, sha512)]
35              -halg may be specified more than once
36
37       [-ty   IMA log format (default type 1)]
38
39       [-tpm  extend TPM PCRs (default)]
40
41       [-sim  calculate simulated PCRs]
42
43       [-checkhash
44              verify IMA event log hashes]
45
46       [-b    beginning entry (default 0, beginning of log)] A beginning entry
47              after the end of the log becomes a noop
48
49       [-e    ending entry (default end of log)] E.g., -b 0 -e 0 sends one en‐
50              try
51
52       [-l    time  -  run in a continuous loop, sleep 'time' seconds betwteen
53              loops] The intent is that this be run without specifying -b  and
54              -e  Afer  each pass, the next beginning entry is set to the last
55              entry +1
