NAME

       fahash - sequence hash builder for reverse e-PCR

SYNOPSIS

       fahash [-hV] -b hash-file [-w wdsize] [-f period] [-F fragment_min,fragment_max] [-k] [-c cachesize] [-v 1|2] famap-file ...

       fahash [-hV] -T hash-file [-o outfile]

DESCRIPTION

       The program fahash is part of the e-PCR suite and is used to build hash-files, and output word usage statistics for reverse e-PCR searches.

OPTIONS

       -b hash-file
	      Build hash tables (hash-file) from sequence files,

       -T hash-file
	      Print word usage statistics for hash-file

       -o outfile
	      Write output to file `outfile'

   build-options:
       -w wordsize
	      Set word size when building hash tables

       -f period
	      Set discontiguity when building hash tables

       -k     Skip repeats when building hash-file

       -F min,max
	      Set watermarks for fragment size (in Mb) (version 1 only)

       -c cachesize
	      Set cache size (version 2 only)

       -v ver Use format version (1|2, 2 is default)

EXAMPLE

	famap -tN -b genome.famap org/chr_*.fa

	fahash -b genome.hash -w 12 -f3 ${PWD}/genome.famap

	re-PCR -s genome.hash -n1 -g1 ACTATTGATGATGA AGGTAGATGTTTTT 120-200

NAME

       tb_polgen - manage tboot verified launch policy

SYNOPSIS

       tb_polgen COMMAND [OPTION]

DESCRIPTION

       tb_polgen is used to manage tboot verified launch policy.

COMMANDS

       --create
	      Create an empty tboot verified launch policy file.

	      --type nonfatal | continue | halt
		     Nonfatal  means  ignoring all non-fatal errors and continuing. Continue means ignoring verification errors and halting other-
		     wise. Halt means halting on any errors.

	      [--ctrl policy-control-value]
		     The default value 1 is to extend policy into PCR 17.

	      policy-file

       --add  Add a module hash entry into a policy file.

	      --num module-number | any
		     The module-number is the 0-based module number corresponding to modules loaded by the bootloader.

	      --pcr TPM-PCR-number | none
		     The TPM-PCR-number is the PCR to extend the module's measurement into.

	      --hash any | image

	      [--cmdline command-line]
		     The command line is from grub.conf, and it should not include the module name (e.g. "/xen.gz").

	      [--image image-file-name]

	      policy-file

       --del  Delete a module hash entry from a policy file.

	      --num module-number | any
		     The module-number is the 0-based module number corresponding to modules loaded by the bootloader.

	      [--pos hash-number]
		     The hash-number is the 0-based index of the hash, within the list of hashes for the specified module.

	      policy-file

       --unwrap
	      Extract the tboot verified launch policy from a TXT LCP element file.

	      --elt elt-file

	      policy-file

       --show policy-file
	      Show the policy information in a policy file.

       --help Print out the help message.

       --verbose
	      Enable verbose output; can be specified with any command.

EXAMPLES

       tb_polgen --create --type nonfatal vl.pol

       tb_polgen --add --num 0 --pcr none --hash image --cmdline "cmdline" --image /boot/xen.gz vl.pol

       tb_polgen --add --num 1 --pcr 19 --hash image --cmdline "cmdline" --image /boot/vmlinuz-2.6.18.8-xen vl.pol

       tb_polgen --add --num 2 --pcr 19 --hash image --cmdline "" --image /boot/initrd-2.6.18.8-xen.img vl.pol

       tb_polgen --del --num 1 vl.pol

       tb_polgen --show --verbose vl.pol

   Note1:
       It is not necessary to specify a PCR for module 0, since this module's measurement will always be extended to PCR 18.  If a PCR	is  speci-
       fied, then the measurement will be extended to that PCR in addition to PCR 18.

   Note2:
       --unwrap  is  not  implemented correctly. There should be a defined UUID for this and that should be checked before copying the data. There
       should be a wrap or similar command to generates an element file for a policy.
