Hi, Guz!
I'm working on a scripts compiler which needs a function to generate random strings. I think REGX may be a good solution to restrict the string format. Before DIYing I'd like asking for any existing libs or codes.

Tspi_TPM_GetRandom(3) Library Functions Manual Tspi_TPM_GetRandom(3)
TCG Software Stack Developer's Reference
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
