Please note that this is not an official Google product.

TPM 1.2 support is best effort, meaning we will accept fixes for TPM 1.2, but
testing is not covered by CI.

## Installation

The go-attestation package is installable using go get: `go get github.com/google/go-attestation/attest`

### TPM1.2
By default, go-attestation does not build in TPM1.2 support on Linux.
Linux users must install [`libtspi`](http://trousers.sourceforge.net/) and its headers if they need TPM 1.2 support. This can be installed on debian-based systems using: `sudo apt-get install libtspi-dev`.
Then, build go-attestation with the `tspi` [build tag](https://pkg.go.dev/go/build#hdr-Build_Constraints) `go build --tags=tspi`.

Windows users can use go-attestation with TPM1.2 by default.
Linux users must install `libtspi` and its headers. This can be installed on debian-based systems using: `sudo apt-get install libtspi-dev`.
