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 : |
The number of bytes requested by the caller.
|
• |
-f , --force : |
Force overwriting the output file.
|
• |
-o , --data = FILENAME or - (for stdout): |
The returned random bytes.
|
• |
--hex |
Convert the output data to hex format without a leading “0x”.
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. |
To successfully use the manpages feature requires the manpages to be installed or on MANPATH , See man (1) for more details.
|
• |
-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.
