Developer Demonstrates Sending Raw TPM 2.0 Commands via Windows TBS in Rust

A developer has published a technical walkthrough on using Windows TPM Base Services (TBS) to send raw TPM 2.0 commands directly through Rust code. The guide covers the full TPM2_GetRandom workflow, including creating a TBS context, marshalling the command, submitting it, and parsing the response to retrieve random bytes. TPM2_GetRandom was chosen as the example because it requires no session and has minimal parameters, making it one of the simpler TPM commands to implement. The tutorial relies on the windows-sys crate and highlights key details such as big-endian byte encoding for TPM command headers. Notably, the TPM may return fewer random bytes than requested if it cannot generate the full amount in a single operation.
