Overview
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.

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

-
--help -
Print out the help message.
