These examples are not working with tpm 2.0 simluator

[kvijay1918]

I m using a Simulator from IBM,
https://francislampayan.medium.com/how-to-setup-tpm-simulator-in-ubuntu-20-04-25ec673b88dc

I have configured this simulator in my Vm which is ubuntu 20.04 and am able to run tpm2 commands of tpm2-tools there successfully.

I have tried your examples. i.e. sign_with_rsa

It is expecting a file /dev/tpm0. But simulator won't create this file. Hence resulting into error. I tried removing readwritecloser pointer from your code, but at the end call, it is being used. So I can't remove this.

Help me to fix this.
