This is a simple daemon designed to manage configurartion data for an embedded device. Its based on a customized OTA Community Edition device-gateway endpoint, but the idea used could be generic to any system wanting to employ secure configuration management.
How It Works
OTA devices communicate with a device-gateway using SSL client authentication. This means the public key of each device is known. By default, devices will have Ellipitcal Curve keys. Using a technique known as ECIES a the configuration values can be encrypted client-side and sent to the device-gateway so that it has no knowledge of a device's configuration values. The device can then pull down the encrypted configuration and use its private key to decrypt.
The encrypted file is stored to a persistent location on disk. At boot, a fioconfig can extract this data to tmpfs (/var/run/secrets) so that they are only available at runtime.
How to build
make bin/fioconfig-linux-amd64
make test
