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/tss_structs.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 SEE ALSO

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 SEE ALSO
