lcp_crtpol: create a TXT v1 Launch Control Policy


lcp_crtpol - create a TXT v1 Launch Control Policy


lcp_crtpol -t policy-type [-a hashalg] [-v version] [-sr SINIT-revocation-counter] [-s srtm-file] [-m mle-file] [-o policy-file] [-b policy-data-file] [-pcf policy-control-field] [-h]


lcp_crtpol is used to create a TXT v1 LCP policy (and optionally policy data), which can later be written to the TPM. The policy created are for platforms produced before 2009 (Weybridge, Montevina, McCreary).


-t policy-type
Policy type can be UINT8 or string. 5 strings are supported for the reserved LCP policy types. Strings and default policy type values for each string are:
0 or "hashonly"
1 or "unsigned"
2 or "signed"
3 or "any"
4 or "forceowner"
-a hashalg
Hash algorithm. Currently we only support SHA-1 algorithm: 0 OR 'sha1'.
-v version
Version number. Currently it can be set to 0 or 1 if specified. The default value is 0.
-sr SINIT-revocation-counter
The default sinit revocation counter is 0.
-s srtm-file
File name of platform configuration data, as produced by lcp_crtpconf.
-m mle-file
File name of file containing the MLE hash values. This is a text file that contains one SHA-1 hash per line. The value of the hash must be hexadecimal values, specified either a single un-deliminated set or as space-delimited two-character (i.e. one byte) values. This can be produced by the lcp_mlehash command.
-o policy-file
File name to store the output policy.
-b policy-data-file
File name to store the LCP Policy data.
-pcf policy-control-field
The default policy control field value is 0.
