# About
This is very stupid CGo bindings for [tpm2-tss](https://github.com/tpm2-software/tpm2-tss).
# Prepare
Currently, the package expects libtss2 of version 2.3.2 be installed.
```sh
apt-get install -y libtss2-dev
go get -d github.com/xaionaro-go/tpm2-tss/...
cd $(go env GOPATH)/src/github.com/xaionaro-go/tpm2-tss
git submodule update --init --recursive
```
# Example
```go
package main
import (
"fmt"
"github.com/google/go-tpm/tpm2"
"github.com/xaionaro-go/tpm2-tss/cgo_tpm2_tss"
)
func main() {
var ectx *cgo_tpm2_tss.EsysContext
pcrIndex := cgo_tpm2_tss.EsysTr(cgo_tpm2_tss.EsysTrPcr0)
digests := []cgo_tpm2_tss.TpmlDigestValues{{
Count: 1,
Digests: [16]cgo_tpm2_tss.TpmtHa{
{
Hashalg: cgo_tpm2_tss.TpmiAlgHash(tpm2.AlgSHA1),
Digest: cgo_tpm2_tss.TpmuHa{1, 2, 3, 4},
},
},
}}
var rc cgo_tpm2_tss.Tss2Rc
var tcti *cgo_tpm2_tss.Tss2TctiContext
rc = cgo_tpm2_tss.Tss2TctildrInitialize("", &tcti)
if rc != cgo_tpm2_tss.Tss2RcSuccess {
panic(fmt.Sprintf("0x%08X", rc))
}
rc = cgo_tpm2_tss.EsysInitialize(&ectx, tcti, &cgo_tpm2_tss.Tss2AbiVersion{
Tsscreator: 1,
Tssfamily: 2,
Tsslevel: 1,
Tssversion: 108,
})
if rc != cgo_tpm2_tss.Tss2RcSuccess {
panic(fmt.Sprintf("0x%08X", rc))
}
rc = cgo_tpm2_tss.EsysPcrExtend(ectx, pcrIndex, cgo_tpm2_tss.EsysTrPassword, cgo_tpm2_tss.EsysTrNone, cgo_tpm2_tss.EsysTrNone, digests)
if rc != cgo_tpm2_tss.Tss2RcSuccess {
panic(fmt.Sprintf("0x%08X", rc))
}
fmt.Println("SUCCESS")
}
```
Result:

If you need any of these functions then create an issue. I'll take a look if
it is possible to easily add the function :)
