Encryption
Log files can be encrypted on the device. Here, data is streamed through an AES-GCM encryption
scheme prior to persistence on the SD card. Encrypted files have *.MFE as file extension.
Note: It is recommended to use a 40+ character password for proper encryption
Decryption can be done using an implementation of the PBKDF2 algorithm or via CANedge tools (see
the CANedge Intro).
0.4.3 Real-Time-Clock
This page documents the real-time-clock configuration
0.4.3.1 Configuration file fields
This section is autogenerated from the Rule Schema file.
Real-Time Clock (RTC) ‘‘ ‘‘
Time synchronization method properties.sync
Internal real-time-clock synchronization method. The real-time-clock is maintained when the device is
off.
type: integer default: 0 options: Retain current time: [0] Manual update: [1]
Time zone (UTC-12 to UTC+14) properties.timezone
Adjustment in full hours to the UTC time. Includes daylight savings time if applicable.
type: integer default: 0 minimum: -12 maximum: 14
Adjustment (-129600 to 129600 seconds) properties.adjustment
Adjustment in seconds to the UTC time. Can be used for fine tuning the internal time.
type: integer default: 0 minimum: -129600 maximum: 129600
0.4.3.2 Configuration explained
This section contains additional information and examples.
The CANedge uses a real-time clock (RTC) with battery backup, which allows it to retain the absolute
date & time when the device is not powered. The RTC enables the CANedge to add absolute timestamps
to recorded messages. The RTC is set to UTC time during production.
Time-zone changes and minor adjustments can be done via the timezone and adjustment fields.
