# GSSAPI wrapper for gokrb5

The [github.com/bodgit/gssapi](https://godoc.org/github.com/bodgit/gssapi)

package implements a GSSAPI-like wrapper around the

[github.com/jcmturner/gokrb5](https://github.com/jcmturner/gokrb5) package.

Sample Initiator (Client):

```golang

package main

import (

	. "github.com/bodgit/gssapi"

	"github.com/jcmturner/gokrb5/v8/gssapi"

)

func main() {

	initiator, err := NewInitiator(WithRealm("EXAMPLE.COM"), WithUsername("test"), WithKeytab[Initiator]("test.keytab"))

	if err != nil {

		panic(err)

	}

	defer initiator.Close()

	output, cont, err := initiator.Initiate("host/ssh.example.com", gssapi.ContextFlagInteg|gssapi.ContextFlagMutual, nil)

	if err != nil {

		panic(err)

	}

	// transmit output to Acceptor

	signature, err := initiator.MakeSignature(message)

	if err != nil {

		panic(err)

	}

	// transmit message and signature to Acceptor

}

```

Sample Acceptor (Server):

```golang

package main

import (

	. "github.com/bodgit/gssapi"

	"github.com/jcmturner/gokrb5/v8/gssapi"

	"github.com/jcmturner/gokrb5/v8/iana/nametype"

	"github.com/jcmturner/gokrb5/v8/types"

)

func main() {

	principal := types.NewPrincipalName(nametype.KRB_NT_SRV_HST, "host/ssh.example.com")

	acceptor, err := NewAcceptor(WithServicePrincipal(&principal))

	if err != nil {

		panic(err)

	}

	defer acceptor.Close()

	// receive input from Initiator

	output, cont, err := acceptor.Accept(input)

	if err != nil {

		panic(err)

	}

	// transmit output back to Initiator

	// receive message and signature from Initiator

	if err := acceptor.VerifySignature(message, signature); err != nil {

		panic(err)

	}

}

```
