+# Device IDs
+
+The files contained in [ci](ci) and [prod](prod) directories hold identity information about witness devices.
+`ci` devices are _fused_ and receieve firmware builds at each commit, and `prod` devices are _fused_ witness devices
+which receive only release tagged firmware builds.
+
+End-users are not expected to use these files, they're just being stored here.
+
+## Files
+
+File names are based on the unique and immutable serial number assigned at time of manufacturing of the SoC
+which lies at the core of the device.
+
+The `.pub` file contains a public key which represents the _device_ with the corresponding serial number.
+
+The `.witness.0` file contains a signed note, verifiable with the device's `pub` key, which commits to the
+initial witness identity used by the device to cosign checkpoints.
+
+The body of this note is formed of 4 lines:
+
+1. A line with the text "ArmoredWitness ID attestation v1".
+2. The ASCII encoded HEX representation of the device serial number whose witness public key is below.
+3. The ASCII encoded decimal number, with no leading zeroes, representing the number of times the witness has rolled its identity. Currently this is always "0".
+4. A note Verifier string representing the witness public key which will be used by this device.
+
+The note is signed by the _device_ key corresponding to the serial number on line 2.
+
+The `.bastion.0` file contains a signed note, verifiable with the device's `pub` key, which commits to the
+initial bastion identity used by the device to register with bastion hosts for performing synchronous witnessing.
+
+The body of this note is formed of 4 lines:
+
+1. A line with the text "ArmoredWitness BastionID attestation v1".
+2. The ASCII encoded HEX representation of the device serial number whose bastion ID is below.
+3. The ASCII encoded decimal, with no leading zeroes, representing the number of times the witness has rolled its bastion identity. Currently this is always "0".
+4. A 64 character ASCII HEX representation of the device's bastion ID.
+
+The note is signed by the _device_ key corresponding to the serial number on line 2.
