# Get random
|
|
|
|
This example demonstrates the use of ESAPI.get_random
|
|
|
|
The code will:
|
|
|
|
* setup the ESAPI interface
|
|
* send a TPM_STARTUP clear command
|
|
* request 8 random numbers from the TPM
|
|
* print out the result
|
|
|
|
## Setup and Variables
|
|
|
|
No specific setup is required. You may wish to change the number of bytes returned in the `get_random` call.
|
|
|
|
## Running
|
|
|
|
To run type `python3 quote.py`
|
|
|
|
Errors might be generated as the pytss libraries search for a suitable TPM device. If everything is successful then a random number will be shown.
|
|
|
|
## Output
|
|
|
|
```bash
|
|
~/tpm.dev.tutorials/PythonExamples$ python3 randomnumber.py
|
|
type is <class 'tpm2_pytss.types.TPM2B_DIGEST'>
|
|
r is a10ab7558675a56c
|
|
