Two comments: 1 = The intent of the command line tools was for rapid prototyping scripts against a SW TPM, and then as sample code for writing the application. 2 - If you really want to script against a hardware TPM, it can be done. Simply place a proxy between the TSS and the TPM device driver. The proxy passes commands from the TCP socket to the TPM device driver. It keeps the connection open so the resource manager doesn't flush between transactions. The proxy can be obtained from here. It's from TPM 1.2 days, but it works for TPM 2.0 as well. https://sourceforge.net/projects/ibmswtpm/files/?source=navbar
