Using TREZOR as a hardware SSH agent
See SatoshiLabs' blog post about this feature:
Screencast demo usage
Simple usage (single SSH session)
Advanced usage (multiple SSH sessions from a sub-shell)
Using for GitHub SSH authentication (via trezor-git utility)
Installation
First, make sure that the latest trezorlib Python package
is installed correctly (at least v0.6.6):
$ apt-get install python-dev libusb-1.0-0-dev libudev-dev
$ pip install Cython trezor
Then, install the latest trezor_agent package:
$ pip install trezor_agent
Finally, verify that you are running the latest TREZOR firmware version (at least v1.3.4):
$ trezorctl get_features
vendor: "bitcointrezor.com"
major_version: 1
minor_version: 3
patch_version: 4
...
Public key generation
Run:
/tmp $ trezor-agent ssh.hostname.com -v > hostname.pub
2015-09-02 15:03:18,929 INFO getting "ssh://ssh.hostname.com" public key from Trezor...
2015-09-02 15:03:23,342 INFO disconnected from Trezor
/tmp $ cat hostname.pub
ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBGSevcDwmT+QaZPUEWUUjTeZRBICChxMKuJ7dRpBSF8+qt+8S1GBK5Zj8Xicc8SHG/SE/EXKUL2UU3kcUzE7ADQ= ssh://ssh.hostname.com
Append hostname.pub contents to ~/.ssh/authorized_keys
configuration file at ssh.hostname.com, so the remote server
would allow you to login using the corresponding private key signature.
Usage
Run:
/tmp $ trezor-agent ssh.hostname.com -v -c
2015-09-02 15:09:39,782 INFO getting "ssh://ssh.hostname.com" public key from Trezor...
