# xtt-python

[](https://badge.fury.io/py/xtt)
[](https://travis-ci.org/xaptum/xtt-python)

A Python module (`xtt`) that encapsulates the [XTT Trusted
Transit](https://github.com/xaptum/xtt) protocol for securing Internet
of Things (IoT) devices.

## Installation

``` bash
pip install xtt
```

The package is published to PyPI for Python 2.7 and 3.3+ for Linux and
OS X. `pip` installs all dependencies, including `xtt` itself.

## Quick-Start

``` python
import socket
import xtt

# In these examples, we assume the id, certs, and keys needed to run
# an XTT client handshake are available as files.

# Load root certificate, used to authenticate the server
root_id = xtt.CertificateRootId.from_file("root_id.bin")
root_pubkey = xtt.ED25519PublicKey.from_file("root_pub.bin")

# Load the server id
server_id = xtt.Identity.from_file("server_id.bin")

# Load the DAA group information
group_basename = b'BASENAME'
group_gpk = xtt.LRSWGroupPublicKey.from_file("daa_gpk.bin")
group_id = xtt.GroupId(hashlib.sha256(group_gpk.data).digest())
group_cred = xtt.LRSWCredential.from_file("daa_cred.bin")
group_secretkey = xtt.LRSWPrivateKey.from_file("daa_secretkey.bin")
group_ctx = xtt.ClientLRSWGroupContext(group_id, group_secretkey,
group_cred, group_basename)

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
sock.connect(('192.0.2.1', 4443))

xtt_sock = xtt.XTTClientSocket(sock,
version = xtt.Version.ONE,
suite_spec = xtt.SuiteSpec.XTT_X25519_LRSW_ED25519_CHACHA20POLY1305_SHA512,
group_ctx, server_id, root_id, root_pubkey)
xtt_sock.start()
my_identity = xtt_sock.identity
my_public_key = xtt_sock.longterm_public_key
my_private_key = xtt_sock.longterm_private_key
```
