Library to check and decrypt Lora PHYPayload
To install:
npm install lora
To test in node using the default appSKey and nwkSKey 2B7E151628AED2A6ABF7158809CF4F3C:
var lora = require('lora');
lora.getPayload('QAESAwKBbgACAbB2c5M9hkMWDus2m9lrqJ63NyclM+XZrkifwye9SPgA');
// should return an object with ascii: AABBCCDDEEFFGGHHIIJJKKLLMMNN
getPayload(data, nwkSKey, appSKey)
Check if the PHYPayload is valid (correct MIC) and returns an object with the decrypted payload as an object containing:
- array: array containins the decrypted bytes
- ascii: bytes converted to ascii
- hex: string containing the data as hexadecimal
Parameters:
- data: array, base64 or hex encoded PHYPayload
- nwkSKey: network session key (default: 2B7E151628AED2A6ABF7158809CF4F3C)
- appSKey: application session key (default: 2B7E151628AED2A6ABF7158809CF4F3C)
checkMIC(data, nwkSKey)
Check if the PHYPayload MIC (message integrity code) is correct (returns true or false).
Parameters:
- data: array, base64 or hex encoded PHYPayload
- nwkSKey: network session key (default: 2B7E151628AED2A6ABF7158809CF4F3C)
debug(data, nwkSKey, appSKey)
Returns an object with all the information about the PHYPayload and the corresponding hierarchy
Parameters:
- data: array, base64 or hex encoded PHYPayload
- nwkSKey: network session key (default: 2B7E151628AED2A6ABF7158809CF4F3C)
- appSKey: application session key (default: 2B7E151628AED2A6ABF7158809CF4F3C)
