We just release Kryptonite (https://krypt.co https://krypt.co), an HSM for your SSH private key on your phone. The private key never leaves your phone. Pair your phone with your computer to create a secure channel (channel is encrypted + signed with session keys only known to your computer and phone). Every time you SSH, the computer calls out to your phone over this channel and asks you to approve a signature. SSH logins with simple push notification approvals. Code is public: https://github.com/kryptco https://github.com/kryptco.
