Project history

go-tpm-tools dates to Google's 2018 TPM 2.0 work and explicitly narrows its scope to TPM 2.0 rather than TPM 1.2. The README frames the library as a complement to Go-TPM: Go-TPM supplies lower-level TPM access, while go-tpm-tools adds simplified APIs and workflows around attestation, signing, import, event logs, and server-side verification. gotpm is exposed from the same repository as the user-facing CLI for exercising TPM operations without writing Go code.

Adoption history

The package-manager footprint is modest compared with broader security scanners, but the Homebrew formula and the repository's documented `go install github.com/google/go-tpm-tools/cmd/gotpm@latest` path made gotpm available to developers who wanted a Go-native TPM utility. Adoption is tied to hardware-backed security, confidential-computing, and attestation users rather than general-purpose shell workflows.

How it is used

gotpm is installed either with `go install` from the repository or by building the `cmd/gotpm` directory from a clone. The README directs users to `gotpm --help` and per-command help, while the surrounding packages document TPM 2.0 operations such as signing, attestation, PCR reads, sealing and unsealing, NV data reads, and TCG event-log handling.

Why package nerds care

For package maintainers, gotpm is a small but useful example of a hardware-facing Go CLI where distribution quality depends on CGO/OpenSSL simulator edges, Go toolchain support, and whether the host actually has TPM 2.0 access. It also sits in the package ecosystem around google/go-tpm, which matters for people tracking Go security tooling and reproducible attestation utilities.
