NAME¶

tss2_getrandom(1) - # SYNOPSIS

tss2_getrandom [OPTIONS]

SEE ALSO¶

fapi-config(5) to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for the Fapi metadata storages.

fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys and operations of a specific TPM interaction like the name hash algorithm, the asymmetric signature algorithm, scheme and parameters and PCR bank selection.

DESCRIPTION¶

tss2_getrandom(1) - This command uses the TPM to create an array of random bytes.

OPTIONS¶

These are the available options:

•

-n, --numBytes=INTEGER:

•

-f, --force:

•

-o, --data=FILENAME or - (for stdout):

•

--hex

COMMON OPTIONS¶

This collection of options are common to all tss2 programs and provide information that many users may expect.

•

-h, --help [man|no-man]: Display the tools manpage. By default, it attempts to invoke the manpager for the tool, however, on failure will output a short tool summary. This is the same behavior if the “man” option argument is specified, however if explicit “man” is requested, the tool will provide errors from man on stderr. If the “no-man” option if specified, or the manpager fails, the short options will be output to stdout.

•

-v, --version: Display version information for this tool, supported tctis and exit.

EXAMPLE¶

    tss2_getrandom --numBytes=20 --data=- | hexdump -C
    

RETURNS¶

0 on success or 1 on failure.
