NAME

       tpm_nvinfo

SYNOPSIS

       tpm_nvinfo [OPTIONS]

DESCRIPTION

       tpm_nvinfo displays information about defined NVRAM areas. The user may restrict it to display only a single NVRAM area by providing an
       index or may choose ton only list available NVRAM areas indices without displaying the NVRAM areas' detailed information.

       The following options are supported:

       -h, --help
	   Display command usage info.

       -v, --version
	   Display command version info.

       -l, --log [none|error|info|debug]
	   Set logging level.

       -i, --index (optional parameter)
	   Only display the NVRAM area with the given index. If this option is not provided all NVRAM areas will be displayed.

       -n, --list-only (optional parameter)
	   Only display the defined NVRAM areas' indices.

NAME

       tpm_nvread

SYNOPSIS

       tpm_nvread [OPTIONS]

DESCRIPTION

       tpm_nvread reads data from an NVRAM area and either displays them or writes them into a file. The user must provide the index of the NVRAM
       area. If the user provided the number of bytes to read then this will be the maximum number of bytes that will be read from the NVRAM area,
       otherwise the whole NVRAM area will be read. Some NVRAM areas only allow read sizes of zero, i.e., NVRAM area with index 0. Optionally an
       offset into the NVRAM area can be given where the reading of the data is to start. If the NVRAM area has permission bits set that require
       owner or NVRAM area authentication, then the password must be provided via the password option.

       The following options are supported:

       -h, --help
	   Display command usage info.

       -v, --version
	   Display command version info.

       -l, --log [none|error|info|debug]
	   Set logging level.

       -u, --unicode
	   Use TSS UNICODE encoding for passwords to comply with applications using TSS popup boxes

       -z, --well-known
	   Use a secret of all zeros (20 bytes of zeros) as either the NVRAM area or owner secret.

       -p, --password
	   Depending on what type of authentication is required for the NVRAM area, this must either be the NVRAM area or owner password.

	   A password may be directly provided for example by using '--password=password' or '-ppassword'. If no password is provided then the
	   program will prompt the user for the password.

       -i, --index
	   The index of the NVRAM area.  The parameter may either be a decimal number or a hexadecimal number starting with '0x'.

       -s, --size
	   The number of bytes to read from the NVRAM area.  The parameter may either be a decimal number or a hexadecimal number starting with
	   '0x'.

       -n, --offset (optional parameter)
	   The offset into the NVRAM area from where to start reading.	The parameter may either be a decimal number or a hexadecimal number
	   starting with '0x'.

       -f, --filename (optional parameter)
	   The name of a file the read data will be written into. If no filename is given the data will be printed to stdout.
