* Signing support with MAX_PAYLOAD>32 Support in the signing backends to handle configurations where MAX_PAYLOAD is more than 32 bytes. Fixes #748 * Support big message signatures Support for signing messages larger than 32 bytes. This is not fully testable with the current version of the library but the change would add theoretical support for signing any sized messages. Fixes #749 * Have gw properly indicate whitelisting preferences If the gateway hold a signing whitelist, inform all nodes of this requirement and not just nodes that hold whitelists themselves. Fixes #806 * Harden security The flag MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL has been removed. Gateway will now request signatures from everyone by default. In addition to this, no nodes in the network will allow clearing of signing/whitelisting preferences by OTA commands by default. If the old behaviour is needed (suitable for gradual signing roll out and development purposes) a new flag, MY_SIGNING_WEAK_SECURITY can be set. Fixes #807 * Signing debug messages rewritten All signing related debug has been rewritten to better match other core debug printouts. Also, backends are updated to have a smaller implementation delta. * Simplified signing option implemented Enable by MY_SIGNING_SIMPLE_PASSWD. Signing, and signing requirements will be enabled, as will encryption. Whitelisting is optional. The value provided to MY_SIGNING_SIMPLE_PASSWD is used as HMAC and AES key. Whitelists use the first 8 bytes of the password and the ninth byte from the node ID as serial. Password is required to be at least 8 characters wide. It is zero padded if it is not long enough to cover the AES (16 bytes) and HMAC (32 bytes) keys. It is not recommended to have a password shorter than 32 bytes, and there is no need for a password longer than 32 bytes. * Add documentation section for signing debug * Add nRF5 encryption to simple signing option * Restructure MySigning documentation * Minor fixes for Linux

* The MySensors Arduino library handles the wireless radio link and protocol
|
|
* between your home built sensors/actuators and HA controller of choice.
|
|
* The sensors forms a self healing radio network with optional repeaters. Each
|
|
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
|
|
* network topology allowing messages to be routed to nodes.
