NAME
lcp2_crtpolelt - create an Intel(R) TXT policy element of specified type.
SYNOPSIS
lcp2_crtpolelt COMMAND [ ELEMENT TYPE OPTIONS ] [OPTION]
DESCRIPTION
lcp_crtpolelt is used to create an Intel(R) TXT policy element of specified type. Supports LCP elements both in current and legacy formats: LCP_MLE_ELEMENT2, LCP_STM_ELEMENT2, LCP_PCONF_ELEMENT2, LCP_PCONF_ELEMENT, LCP_MLE_ELEMENT and LCP_CUSTOM_ELEMENT.
COMMANDS
--create --type type --out FILE [--ctrl pol_elt_ctr1] create a policy element specified by the --type option. --type type type of element. Must be first option. See below for type strings and their options --out FILE output file name [--ctrl value] PolEltControl field (hex or decimal) --show file [FILE] show a policy element --version show tool version --verbose enable verbose output; can be specified with any command --help print out the help message
OPTIONS
The --create command requires additional parameters depending on the element's type mle2 [--minver ver] [--alg algorithm] file [file...] --minver ver minimum version of SINIT (hex or decimal) --alg <sha1|sha256|sha386|sha512> hash algorithm file [file...] one or more text files, each containing one or more MLE hashes (as text, one hash per line); Hash files can be created with lcp2_mlehash. custom --uuid UUID file --uuid UUID UUID in format: {0xaabbccdd, 0xeeff, 0xgghh, 0xiijj, {0xkk 0xll, 0xmm, 0xnn, 0xoo, 0xpp}} or "--uuid tboot" to use default file file containing element data sbios [--alg algorithm] file [file...] --alg <sha1|sha256|sha386|sha512> hash algorithm file [file...] one or more files containing one or more BIOS hashes (as text, one hash per line); the first hash in the first file will be the fallback hash stm [--alg algorithm] file [file...] --alg <sha1|sha256|sha386|sha512> hash algorithm file [file...] one or more text files, each containing one or more STM hashes (as text, one hash per line); pconf2 --alg algorithm [--pcrN hash_value] --alg <sha1|sha256|sha386|sha512> PCR hash algorithm --pcrN hash_value PCR value for PCR #N, where 0 <= N <= 7. mle [--minver ver] file [file...] --minver ver minimum version of SINIT (hex or decimal) file [file...] one or more text files, each containing one or more MLE SHA1 hashes (as text, one hash per line); Hash files can be created with lcp2_mlehash. pconf file [file...] one or more text files, each containing PCR information; Each file should have the following structure: first line should be: 'locality:<value>' followed by up to 8 lines, each representing one PCR (0 to 7) and its contents: e.g. Locality represents TPM's locality at release. It is a byte, of which bits 0 to 4 represent their respective locality (bit0 - locality0 and so on). Bits 5-7 are reserved and must be 0. Value must be at least 1 - locality0 selected, and at most 0x1F (all localities selected).
EXAMPLES
Create MLE element: lcp2_crtpolelt --create --type mle --out mle.elt --ctrl 0x00 --alg sha256 --minver 0 mle_hash Create PCONF2 element: lcp2_crtpolelt --create --type pconf2 --out pconf2.elt --ctrl 0x00 --alg sha256 --pcr0 <PCR[0] hash> --pcr3 <PCR[3] hash> Create PCONF element: lcp2_crtpolelt --create --type pconf pcrInfo1.txt pcrInfo2.txt --out pconf2.elt --ctrl 0x00
