LCP_MLEHASH(8)

NAME
lcp2_mlehash - generate a hash of a TXT MLE binary file and print it to STDOUT as text.

SYNOPSIS
lcp2_mlehash [--create] [--cmdline cmdline] [--alg hashalg] [--help] [--verbose] mle-file

DESCRIPTION
lcp2_mlehash is used to generate a hash of the portion of an executable file that contains the Intel(R) TXT measured launched environment (MLE). In the MLE binary file, the portion of the file to be used as the MLE is specified in the MLE header structure. If verbose mode is not used, the output is suitable for use as the mle-file to the lcp2_crtpolelt command.

OPTIONS

mle-file
    File name of the MLE binary. If it is a gzip file then it will be un-ziped before hashing.

--create
    Create a hash.

--cmdline cmdline
    Specify quote-delimited command line. It is important to specify the command line that is used when launching the MLE or the hash will not match what is calculated by SINIT.

--alg hashalg
    Specify the hash algorithm to use. Supported values are sha1, sha256, sha384 and sha512.

--help
    Print out the help message.

--verbose
    Verbose mode, display progress indications.

EXAMPLES
    lcp2_mlehash --create --cmdline "logging=memory,serial,vga" --alg sha1 /boot/tboot.gz > mle-hash
