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)

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...

Make sure to confirm SSH signature on the Trezor device when requested.

Accessing remote Git repositories

Use your SSH public key to access your remote repository (e.g. GitHub):

$ trezor-agent -v -e ed25519 git@github.com | xclip

Use the following Bash alias for convinient Git operations:

$ alias git_hub='trezor-agent -v -e ed25519 git@github.com -- git'

Replace git with git_hub for remote operations:

$ git_hub push origin master
