=== How to get TPM model information? === | |||
The following command will dump found strings from the raw TPM2 certificates: | |||
<syntaxhighlight lang="bash"> | |||
nix-shell -p tpm2-tools --run "tpm2_getekcertificate" | strings | |||
</syntaxhighlight> | |||
Usually, you may find a vendor such as <code>STMicroelectronics</code> or <code>Infineon Technologies</code> and a model such as <code>ST33HTPxAHB61</code>. | |||
To get firmware version information, you might want to look at: | |||
<syntaxhighlight lang="bash"> | |||
nix-shell -p tpm2-tools --run "tpm2_getcap properties-fixed" | |||
</syntaxhighlight> | |||
