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.
