Is the generator for the TPM sources available?

[sharadhr]

The TPM sources used by all the samples, and especially the simulator in TPMCmd, have these telltale lines:

/*(Auto-generated)
 *  Created by TpmStructures; Version 4.4 Mar 26, 2019
 *  Date: Mar  6, 2020  Time: 01:50:09PM
 */

Is the source for this TpmStructures script/binary available? I presume based on this discussion that the generator parses the TPM 2.0 specification itself to generate code.

Equivalent work is in TSS.MSR/TssCodeGen, but that doesn't seem to generate C source code (like is seen in this repository), but rather equivalent structures in higher-level languages.

TpmScripts seems likely, but the repository is empty; there are references to it in this repository's gitignore, too.

Sorry, at the current time, those tools are not available publicly.

@bradlitterell could they be replaced by TssCodeGen?

[bradlitterell]

No TssCodeGen generates TPM client code. Your original request was, I believe, for the TPM implementation code, which is a different tool.

Are there any plans to make the tool publicly available?

[bradlitterell]

Not currently, no. Sorry.

[DemiMarie]

Not currently, no. Sorry.

Understood. Can you provide the reason, or is that also confidential?

[bradlitterell]

Not currently, no. Sorry.

Simple practicality. They are complex and troublesome, and we wouldn't have the bandwidth to explain or support them for arbitrary users. Plus, we have plans to remove them entirely.

Will the replacement be publicly available? I ask because there are changes (like #104) that can only be made in the code generator.
