NAME
Tspi_TPM_GetRandom - generate a random number on the TPM
SYNOPSIS
#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>
#include <tss/tss_typedef.h>

#include <tss/tspi.h>
TSS_RESULT Tspi_TPM_GetRandom(TSS_HTPM hTPM, UINT32 size, BYTE** random);
DESCRIPTION
Tspi_TPM_GetRandom gets a good random number for the purpose of generating symmetric keys, nonces, or seeding a random number generator.
PARAMETERS
hTPM
The hTPM parameter is used to specify the handle of the TPM object. The command to get the TPM to test itself will be sent here.
size
The size parameter is the number of random bytes requested.
random
The random parameter is a pointer to memory containing the random data. This is where the generated number goes. Because this internally
allocates memory, Tspi_Context_FreeMemory should also be used.
RETURN CODES
Tspi_TPM_GetRandom returns TSS_SUCCESS on success, otherwise one of the following values is returned:
TSS_E_INVALID_HANDLE
hTPM is not a valid handle.
TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
TSS_E_BAD_PARAMETER
One or more parameters is bad.
CONFORMING TO
Tspi_TPM_GetRandom conforms to the Trusted Computing Group Software Specification version 1.1 Golden

NAME
Tspi_TPM_SelfTestFull - perform a self-test of each internal TPM function
SYNOPSIS
#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>
#include <tss/tss_typedef.h>
#include <tss/tss_structs.h>
#include <tss/tspi.h>
TSS_RESULT Tspi_TPM_SelfTestFull(TSS_HTPM hTPM);
DESCRIPTION
Tspi_TPM_SelfTestFull assures that the TPM is functioning as designed. For FIPS certification, crypto modules are required to test them-
selves before they are used, and this command is used to fulfill that requirement. This command can also be used to check the TPM whenever
such a check is desired. This command is not currently implemented.
PARAMETERS
hTPM
The hTPM parameter is used to specify the handle of the TPM object on which the self-tests will be run.
RETURN CODES
Tspi_TPM_GetStatus returns TSS_SUCCESS on success, otherwise one of the following values is returned:
TSS_E_INVALID_HANDLE
hTPM is not a valid handle.
TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
CONFORMING TO
Tspi_TPM_SelfTestFull conforms to the Trusted Computing Group Software Specification version 1.1 Golden

Im new to C, and Im having a hard time getting a random number.
In bash, I would do something similar to the following to get a random number;
#!/bin/bash
seed1=$RANDOM
seed2=$RANDOM
seed3=$RANDOM
SEED=`expr $seed1 * $seed2 / $seed3`
echo ${SEED%.*}
Now, in online examples... (4 Replies)
Lets say I want to pick a random file when I do an "ls" command. I don't have set number of files in each directory.
ls | head -1
This gives me the first one in each directory, is there a way to do the same but pick a random one. (3 Replies)
Hello.
Could anyone help me with my little annoying problem?
I have to generate a 512 MB file made up with random data using DD. After some internet digging I found out that the command is:
dd if=/dev/urandom of=/exemple/file bs=512MB
After running this command the... (2 Replies)
