DEPRECATED

This project is not maintained. Please migrate to Akamai MFA.

Krypton generates and stores an SSH key pair on a mobile phone. The Krypton app is paired with one or more workstations by scanning a QR code presented in the terminal. When using SSH from a paired workstation, the workstation requests a private key signature from the phone. The user then receives a notification and chooses whether to allow the SSH login. For more information, check out krypt.co.

Build Instructions

  1. Follow build instructions in ssh-wire
  2. Open project in Android Studio

Workstation SSH Integration

curl https://krypt.co/kr | sh
